10 Best SEO Agencies for B2B Companies in 2026

To build this list, I went through each agency's website, case studies, and client results to understand what they actually do, not just how they describe themselves. I also looked at which agencies come up in practitioner conversations and B2B marketing communities, where people share honest experiences rather than polished testimonials.

I focused specifically on agencies with documented B2B work: real client names, real metrics, and a clear line from the SEO program to business outcomes like demos, pipeline, or revenue. Agencies that only published traffic numbers without any conversion context didn't make the cut.

There is no single best agency here. Each one on this list serves a different type of company at a different stage. The right fit depends on what you actually need, whether that's fixing a broken technical foundation, building a full content program from scratch, or combining paid and organic under one roof. Read through the breakdowns below before booking any discovery calls.

Quick comparison: 10 B2B SEO agencies at a glance

1. Scale Theory

Scale Theory is a B2B organic growth agency that helps companies build visibility in both Google and AI search. The core pitch is a single managed system, one team handling strategy, execution, and reporting, designed for growth-stage and mid-market B2B SaaS companies where organic has either stalled or never been properly built.

Akshay Krishnan managed SEO across Zoho's product suite, including Zoho CRM, Zoho Analytics, Zoho Meeting, and Zoho People, and also worked with ManageEngine, a leading IT management software company. Praveenkumar Sivaraj, co-founder of Scale Theory, has worked with B2B SaaS companies such as Workativ, Spendflo, Hiver, Site24x7, Hevo Data, Gloroots, and Freightify, helping businesses across workflow automation, IT operations, fintech, data infrastructure, and logistics software grow their organic presence.

What separates Scale Theory from most SEO agencies is the dual-channel structure. Google rankings and LLM citations are treated as one interconnected system, not two separate workstreams, because the authority signals that drive one also drive the other.

Before any content is produced, Scale Theory runs a two-week business immersion phase, mapping buyer journeys, running jobs-to-be-done exercises, and identifying which themes and queries a brand needs to own across search and AI platforms.

Internal AI tracking runs through ScaleX, an in-house system that monitors brand presence across ChatGPT, Perplexity, Gemini, and AI Overviews. It identifies gaps, tracks how visibility shifts over time, and feeds directly into content prioritization, without adding a separate tool cost to the client.

Top 3 services

1. Product-Led SEO Keyword strategy built from the buyer journey up, not from generic keyword volume. This means targeting queries that map to specific stages of evaluation: awareness-level problems, consideration-stage comparisons, and decision-stage searches. Every content piece is tied to a product use case, buyer persona, or conversion path.
2. AI SEO Targeted AI visibility across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Scale Theory maps where a brand is missing or underrepresented in AI-generated answers, builds content to close those gaps, and monitors results through ScaleX. The goal is consistent citation in the prompts your buyers are actually running.
3. Authority Architecture Pillar-cluster content architecture designed for both users and AI systems. Includes topical depth planning, intent-specific page alignment, internal linking structure, and credibility building through expert citations, SME contributions, and structured authority signals.

Notable clients

Scale Theory works primarily with B2B SaaS companies at growth-stage and mid-market.

EdisonOS, a test prep SaaS for SAT/ACT tutors, grew from 9 LLM sessions per month to 534, and reached 100% of demo pipeline sourced from organic SEO by February 2026, with $5.5M in total pipeline added.

Gloroots, a San Francisco-based Employer of Record platform, grew from zero LLM-sourced leads to 20+ per month within four months.

BQP, a quantum-inspired simulation company serving aerospace and defence, grew from approximately 50 to 500 monthly LLM sessions in a highly specialized niche.

Flowcart, an AI-powered WhatsApp commerce platform, reached 200+ monthly LLM sessions within four months of a complete domain rebuild.

Case study: EdisonOS

EdisonOS came to Scale Theory with an organic program that wasn't connecting to pipeline. Demos were coming from paid, not search.

Scale Theory rebuilt the content strategy around the actual job the buyers, independent SAT/ACT tutors, were trying to do. That meant targeting tutor-specific problems (mock test creation, ACT prep workflows, parent communication) instead of student-facing queries.

Results over 18 months: organic clicks grew from 3,475 to a peak of 6,700 per month. LLM sessions grew 59x, from 9 to 534 per month. By February 2026, 13 of 13 monthly demos were sourced entirely from organic SEO, 100% of the pipeline. Total pipeline added: $5.5M.

Pricing: Starting from $1500. Engagements start with a 30-minute strategy call.

2. Onely

Onely is a technical SEO and GEO agency. Their core argument is that most B2B organic programs fail not because of content volume but because search engines and AI systems can't properly crawl, render, index, or extract what's already there. Fix the foundation, then build on it.

They've recently expanded beyond technical SEO into generative engine optimization, structured data, entity clarity, and AI-readiness audits, positioning them for companies that need both the structural fix and the AI visibility layer.

Founder Bartosz Goralewicz sits on the Bing Customer Advisory Board and has been featured by Google Search Central. The agency delivers dev-friendly outputs, Jira access instead of PDF reports, and works directly inside client engineering workflows, not alongside them.

Top 3 services

1. Technical SEO Crawlability, indexation, JavaScript rendering, Core Web Vitals, internal linking, and information architecture. Findings are delivered as prioritized, dev-ready tasks.
2. Generative Engine Optimization (GEO) Structured data implementation, entity clarity, and content formatting for AI answer surfaces. Includes tracking brand mentions and citations across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Their GEO work runs on a content consolidation model, building topical depth as a signal LLMs use to cite brands.
3. Site Migration and AI-Aware Redesign Recovery Structured technical plans for protecting organic and AI search performance during platform moves or site rebuilds. Monitoring is built in from day one, not added reactively after rankings drop.

Notable clients

Onely's named client list includes G2, IKEA, eBay, Realtor.com, Miele, LiveChat, Yotpo, Brainly, and ServiceTitan.

Case study: Stratos Jet Charters

Stratos Jet Charters needed a technical foundation that matched the quality of their service offering. Onely ran a full technical audit and implementation, covering crawlability, information architecture, and on-page structure.

Results: 2,000% increase in overall SEO visibility, 195% increase in organic traffic, and a 1,000% increase in keywords ranking in the top three and top ten positions.

"I don't feel like they are a third-party service provider. I feel that they are an internal part of our team., Joel A. Thomas, CEO, Stratos Jet Charters"

Pricing: Not public. Entry point is a free strategy call.

3. Directive Consulting

Directive is a B2B performance marketing agency for tech and SaaS companies. SEO sits inside a broader strategy tied to pipeline and revenue, paid search, organic, and CRO running from a shared attribution model. They serve 420+ brands and claim over $1B in revenue generated for clients.

Their methodology is called DiscoverabilityOS, a five-step framework covering ICP modeling, buyer journey mapping, brand and demand alignment, conversion optimization, and data-driven scaling. It's built for teams that want one agency owning the full demand generation function, not coordinating between specialists.

They've also launched Stratos, a proprietary AI intelligence platform that unifies CRM, paid media, SEO, and operations data for predictive intelligence and channel attribution. GEO is integrated, not a bolt-on. Their AxisCare case study documents direct SQL generation from ChatGPT referrals.

Named clients include Amazon, Uber Freight, Snap Inc., Calendly, Adobe, Cisco, Gong, ZoomInfo, and BlackLine.

Top 3 services

1. Pipeline-focused SEO (DiscoverabilityOS) SEO tied to revenue attribution, not keyword rankings. Includes topical authority building, keyword and topic clustering around ICP pain points, and data-driven content structured around conversion paths.
2. Integrated paid + organic Paid search and SEO running from the same ICP model and measurement framework. Useful when a team is running both channels separately and losing efficiency because they're not coordinating on keywords, budgets, or content.
3. Generative Engine Optimization (GEO) LLM optimization built into content engagements. Includes llm.txt creation, content restructuring for AI crawlers, dual-channel content planning, and monitoring via their Stratos platform. They report a 56% lift in their own LLM visibility since mid-2025.

Notable clients

AxisCare, a home care software platform, grew scheduled demos 200% year-over-year and organic traffic 70% over nine months. In the GEO phase (2025), LLM referral share grew from under 4% to 15% of all referrals, with 24 net-new leads coming directly from LLM referrals in the first six months.

Case study: AxisCare

AxisCare serves home care scheduling agencies across all 50 US states. Directive ran a two-phase engagement: an SEO phase focused on topical authority and ICP-aligned content, followed by a GEO phase introducing llm.txt, AI-optimized content layouts, and LLM visibility tracking via Scrunch.

SEO phase results (nine months): 200% year-over-year growth in scheduled demos, 70% year-over-year growth in organic traffic.

GEO phase results: LLM referral traffic up 70% quarter-over-quarter; LLM share of total referral traffic from under 4% to 15%; 24 net-new leads sourced directly from ChatGPT and Perplexity in the first six months.

Pricing: Not public. Entry point is a discovery call and free audit.

4. Siege Media

Siege Media has fully pivoted to GEO. Their current positioning is full-service GEO, making B2B brands the answer in AI search, not just a result in Google. They report $148M+ in yearly client traffic value generated across their portfolio.

Their technology stack is what separates them. BlueprintIQ is their proprietary content strategy platform, built to identify keyword opportunities with relevancy-adjusted difficulty scores, run content gap analysis, and produce a freshness scorecard. DataFlywheel is their automated content refresh technology, designed to keep content current at a scale that matters because both LLMs and Google reward fresh, accurate content.

Founder Ross Hudgens authored a book on generative engine optimization. Their research shows comparison and versus pages drive the highest B2B AI traffic volume, which shapes how they structure content programs for SaaS and fintech clients.

Top 3 services

1. Generative Engine Optimization (GEO) Prompt visibility strategy, LLM citation optimization, and bottom-funnel comparison content across ChatGPT, Perplexity, Gemini, and AI Overviews. They use Peec AI for LLM visibility monitoring. Research identifies specific content types (comparisons, best-of lists, original data) that earn the most AI citations in B2B categories.
2. Content production with original research Original data, calculators, and surveys produced specifically to become LLM-citable assets. Their internal data shows an 83% lift in traffic value when content includes unique data, which directly informs their production approach.
3. DataFlywheel (content refresh at scale) Automated quarterly content refreshes built on their proprietary technology. Addresses a core GEO problem: content that doesn't stay current gets displaced by fresher sources in both Google and LLM outputs.

Notable clients

Siege Media works with some of the most recognized B2B SaaS brands: Zendesk, Zapier, HubSpot, Zoom, Instacart, Asana, Drata, Nextiva, ServiceNow, and QuickBooks.

Zendesk: 657% growth in organic blog traffic, 98% LLM visibility for relevant queries (highest among competitors per Peec AI), average LLM mention position of 1.8, and $958,700 increase in traffic value.

Zapier: $6.1M increase in traffic value, 96% LLM visibility.

Mentimeter: 124,000 ChatGPT sessions over six months, 3,400 conversions in a single month.

Case study: Zendesk

Zendesk came to Siege Media with outdated content, falling traffic targets, and UX issues across their blog.

Siege Media built a bottom-funnel "best X" content strategy across both blog and service pages, created gated middle-funnel assets (email templates, calculators), and redesigned key page templates including author bios, the blog homepage, and the resources hub.

Results: 657% increase in organic blog traffic, 98% LLM visibility (highest among competitors), average LLM mention position of 1.8, and $958,700 in traffic value increase. The top individual page, "Best help desk software," generates $68,300 in traffic value alone.

Pricing: Not public. Entry point is a free ROI analysis consultation.

5. Grow and Convert

Grow and Convert is a B2B content and SEO agency built on a specific methodology called Pain Point SEO. Rather than chasing traffic volume, they start from the queries that buyers run when they're actively evaluating options, comparison pages, alternative pages, category keywords, and jobs-to-be-done content, then work backward from there.

Their thesis: ultra-specific, buyer-intent content wins in both Google and AI search. LLMs favor specificity and product detail over generic content. Their AI visibility results on the Toro TMS case study, 91% Google AI Overview visibility and 81% Google AI Mode visibility across tracked prompts, support this.

They've also built Traqer AI (traqer.ai), a proprietary tool that tracks brand mentions across AI models by topic and prompt.

Top 3 services

1. Pain Point SEO Keyword strategy built from conversion intent backward. Targets three types of queries: category keywords (product features, head terms), comparison keywords (vs. competitors, alternatives), and jobs-to-be-done keywords (specific buyer problems and tasks). Every piece is written at sales-conversation depth.
2. Interview-driven content production Content written from client interviews, not generic research. Grow and Convert extracts product-specific insights, competitive differentiators, and buyer language from the client team, then uses those inputs to produce articles that can't be replicated by a competitor running the same keyword list.
3. GEO with Traqer AI Parallel AI search visibility tracking alongside organic SEO. Traqer AI monitors brand citations across ChatGPT, Perplexity, Gemini, and Google AI by topic and prompt. The content strategy is built so the same articles earn both Google rankings and LLM citations.

Notable clients

Grow and Convert works with B2B SaaS companies at SMB to mid-market scale. Named clients include Toro TMS, Leadfeeder, Geekbot, Circuit, and Rainforest QA.

Toro TMS grew inbound revenue from 5% to 25% of total revenue in 18 months. Booked revenue grew 362% year-over-year. Inbound demos went from 0 per month to 17 per month at peak, with a consistent 10-per-month average over the trailing 12 months.

Leadfeeder scaled to 220+ trial signups per month from pain-point content.

Case study: Toro TMS

Toro TMS is a trucking management software platform for bulk haulers. They came to Grow and Convert with zero inbound leads from organic search.

Grow and Convert deployed Pain Point SEO across three keyword types and published 46 interview-driven, product-specific articles over 18 months. Content was structured specifically for both Google and AI search retrieval.

Results: 43 first-page non-branded keyword rankings with a 93% first-page hit rate, 30 keywords in positions 1–3, inbound demos from 0 to 17 per month at peak, and booked revenue growth of 362% year-over-year.

AI visibility (tracked across 90 prompts and 18 topics): 91% on Google AI Overviews, 81% on Google AI Mode, 59% on Perplexity, 50% on Gemini, 35% on ChatGPT.

Pricing: Not public. Contact required.

6. Omniscient Digital

Omniscient Digital is a boutique organic growth agency for B2B software companies, based in Austin, TX. They work exclusively with B2B SaaS and explicitly refuse clients who want cheap content execution, guaranteed quick results, or an agency that does everything.

The boutique model means direct access to senior practitioners, not junior teams after the pitch. Their work connects voice-of-customer research and product positioning to SEO strategy, integrating organic with GTM, product marketing, and sales.

Full-service engagements start at $10,000 per month. They do not run paid, social, or email, purely organic growth.

Top 3 services

1. Organic growth strategy (SEO + GEO) Starts with ICP and buyer pain point research before touching a keyword. Covers competitive analysis, content gap analysis, authority audit, and channel roadmap. GEO is integrated, not bolted on. Their Order.co case study documents LLM-referred traffic converting at 30% versus 5% for traditional organic.
2. Content production with authority building Editorial quality content with unique perspective and original research. Paired with link building at a minimum DR50 standard and digital PR specifically designed for LLM citation signals.
3. Technical SEO + programmatic SEO Technical foundation work alongside programmatic content builds for brands with large keyword surfaces. Structured data, semantic markup, and clean HTML for both search engine and LLM crawlability.

Notable clients and results

Jasper: organic blog sessions +810%, product signups +400x, $4M ARR attributed to blog content.

Order.co: organic blog sessions +2,117%, blog conversions +39x. LLM-referred traffic converts at 30% versus 5% for traditional organic search.

AppSumo: organic traffic +843%, revenue from organic +340%.

Convert: LLM visibility +81%, AI citations +140% in 60 days.

Case study: Jasper

Jasper (then Jarvis.ai) needed a content program that converted, not just drove traffic. Omniscient Digital ran a four-phase strategy: top-of-funnel traffic first, followed by product-led bottom-funnel content, AI use case content, and competitor comparison pages.

They managed full-service execution through a domain migration from jarvis.ai to jasper.ai, maintaining growth throughout.

Results: organic blog sessions up 810%, product signups up 400x (blog-to-signup conversion rate reached as high as 8%), median time from blog read to signup: 1 minute 53 seconds, $4M ARR attributed to blog content.

Pricing: $10,000/month minimum. Retainer-based. No paid, social, or email services.

7. First Page Sage

First Page Sage is a full-service B2B SEO and thought leadership agency. They claim to be the first agency to formally offer generative engine optimization, launching it in May 2023. Founder Evan Bailyn is cited as the originator of the GEO term and has published detailed algorithm breakdowns for ChatGPT, Gemini, Perplexity, and SearchGPT.

Their model is built for companies with long buying cycles and multiple buyer personas. The flagship product is a high-cadence thought leadership program, approximately 80 pieces of content ghostwritten per year in the client's voice, designed to build topical ownership that compounds over 12+ months.

They work across B2B SaaS, fintech, healthcare, manufacturing, construction, financial services, and cybersecurity. Named clients include Cadence Design Systems, Logitech, Salesforce, Alcoa, Verizon, and U.S. Bancorp.

Top 3 services

1. Thought leadership SEO High-cadence publishing built around topics that matter to your buyers, ghostwritten in the client's voice. Combines long-form blog posts, conversion-optimized landing pages, and sustained topical authority building. Campaigns typically run two to five years.
2. GEO / AEO A systematic framework covering the factors that drive LLM citations: appearing in ranked list articles, inclusion in databases LLMs use for training, domain authority, review management, and social sentiment signals. Platform-specific breakdowns for ChatGPT, Gemini, Perplexity, and SearchGPT.
3. Agentic search optimization A newer service targeting AI agents that do autonomous research across the web. As more B2B buyers delegate vendor research to AI agents, appearing in those results becomes a distinct visibility channel.

Notable clients and results

Cadence Design Systems: 934% increase in keyword rankings, plus record new subscribers, free trial requests, and user signups.

iGPS: 5x improvement in visitor-to-lead conversion rate, 90,000 new users, 368 first-page keywords, and 230 leads worth approximately $15M in lifetime value within two years.

Case study: iGPS

iGPS manufactures and leases reusable plastic pallets for logistics companies. They needed a website and content strategy that spoke to CFOs, CEOs, and operations managers, each with different buying criteria.

First Page Sage built a Hub & Spoke content architecture, fixed technical issues (slow page speed, missing schema, no SSL), and created branded landing pages targeting high-value hub keywords with supporting blog posts for long-tail spoke keywords. Conversion optimization was built into every internal link and CTA.

Results within two years: 5x improvement in visitor-to-lead conversion rate, 90,000 new users, 368 first-page keywords, 230 leads worth approximately $15M in lifetime value.

Pricing: Their own pricing survey benchmarks full-service campaigns at $10,000–$15,000/month. Campaigns typically run two to five years.

8. Obility

Obility is a B2B performance marketing agency built for tech and SaaS companies. They combine paid search, SEO, GEO, paid social, Reddit, content, and revenue attribution under one roof, with the explicit argument that running paid and organic separately produces worse outcomes than running them from the same ICP model and data.

Their three operating principles: don't trust any platform's default settings, build for ease of management, and establish ICP alignment before scaling spend. GEO is an active service line, not a bolt-on.

Obility is one of the few agencies on this list with fully public pricing.

Named clients include Snowflake, Fastly, Cloudflare, Marketo, BlackLine, Equinix, Vultr, Boomi, Cisco, and Autodesk.

Top 3 services

1. Integrated SEO + GEO Technical SEO alongside a dedicated GEO service: Google AI Overview optimization, LLM citation tracking across ChatGPT, Perplexity, Claude, and Google, prompt monitoring, and brand mention strategy. Reddit organic strategy is included as an AI citation play, Reddit is a top cited source for Gemini, Perplexity, and ChatGPT.
2. Paid search for B2B tech Google Ads and Microsoft Ads structured specifically for B2B, CRM-integrated, pipeline-attributed, and built around the assumption that platform defaults optimize for the wrong outcomes. Runs in coordination with organic to avoid bidding on keywords that should rank organically.
3. Revenue attribution Custom Looker dashboards connecting ad platform and analytics data with CRM. Multi-touch attribution, pipeline tracking, and quarterly business reviews. Built for B2B teams that need to show paid and organic contribution to revenue, not just traffic.

ServicePower: 83% increase in traffic from AI search engines quarter-over-quarter, 125% increase in conversions from AI users.

Case study: Boomi

Boomi, a mid-market SaaS company in integration and automation, wanted to expand from technical SEO into GEO, specifically getting cited in Google AI Overviews, ChatGPT, and Perplexity.

Obility ran BOFU long-tail keyword research optimized for AI Overview citation patterns, identified competitor content gaps, built new content collections, optimized existing blog content with FAQ schema, and built a custom reporting dashboard tracking Boomi and competitor rankings across AI Overviews and generative engines.

Results within two months: 20 newly created content pieces ranked in Google AI Overviews, and 40 previously existing blog posts optimized by Obility started appearing in AI-generated search responses.

"Obility has been a great partner in driving our AI growth initiatives. Their proactive research into Boomi's visibility in AI overviews has provided us with valuable insights into where and how we are being featured., Lyndsay Peters, SEO Manager, Boomi"

Pricing (publicly listed)

9. RevenueZen

RevenueZen is a B2B SEO and GEO agency focused on pipeline. Based in Portland, OR, they've built 300+ client partnerships and report an average 384% organic traffic growth across their client base. Their strength is growth-stage B2B companies, including fintech and health tech, building a first serious organic program.

Their GEO practice is among the most developed on this list as a standalone service. They monitor brand citations across ChatGPT, Perplexity, Claude, Gemini, and DeepSeek, implement LLMs.txt and schema across client sites, run digital PR for LLM citation building, and manage Reddit campaigns as a conversational search play.

They also publish a free LLMs.txt generator, a GEO opportunity audit, and a topical authority tool. Their pricing is the most transparent on this list, everything is published on their website.

Top 3 services

1. B2B SEO + GEO (combined) Technical SEO, on-page optimization, and link building alongside a full GEO program. The GEO component includes quarterly AI citation audits, LLM monitoring across five major platforms, schema implementation, digital PR for high-authority citation building, and content structured for AI Overview appearance.
2. Interview-led content creation Content production starting from SME interviews, not keyword research. RevenueZen trains a custom GPT on each client's documents, sales transcripts, and customer conversations to produce a first draft that sounds like the business, then applies multiple rounds of human editorial review.
3. Analytics and pipeline attribution GA4 setup, custom dashboards, CRM integration, and monthly pipeline attribution reporting. Onboarding starts with an analytics audit before any content is produced, because attribution data needs to be clean before organic results can be measured properly.

Notable clients and results

Expensify: 50% increase in SEO-sourced product signups in six months, 4x AI Overview presence in five months, 101% increase in AI-sourced website visitors, 2x improvement in AI signup conversion rate versus organic search.

Incfile: 300% increase in organic search-sourced revenue in 12 months.

PE-backed enterprise AI SaaS (fintech/fraud prevention, unnamed): $3.8M in pipeline from organic in 12 months, 54.76% more SQLs year-over-year.

Case study: Enterprise AI SaaS, $3.8M pipeline in 12 months

A PE-backed enterprise AI SaaS company in financial compliance and fraud prevention had strong organic intent but no SEO foundation. Attribution was broken, the site had crawlability issues, and there was no BOFU content strategy in place.

RevenueZen started with a full analytics audit and GA4 migration to establish clean attribution, then ran a technical SEO audit, content audit, and scaled production with a brief-first process. One optimized solution page targeting a high-priority commercial keyword drove early conversion lift within the first 90 days.

Results at 12 months: $3.8M in pipeline from organic, 54.76% more SQLs year-over-year, 280% increase in top-3 keyword rankings.

10. Avid Demand

Avid Demand is a full-service B2B digital marketing agency based in Boulder, CO. Founded in 1999, they're the most tenured agency on this list, 25+ years working in B2B tech across enterprise software, networking, healthcare IT, manufacturing, and payment processing.

Their model is built around not requiring long-term commitments. Engagements start with a customized 90-Day Improvement Plan, a scoped proposal with defined deliverables, fees, KPIs, and goals. After 90 days, the client decides whether to continue. All ongoing contracts are cancellable with 30 days' notice.

The team average is 15–19 years of digital marketing experience per member. All US-based, no junior staff on accounts. Named clients include Cisco, Logitech, SAP, Nielsen, SUSE, LiveRamp, and Epicor.

2. Integrated paid + organic + analytics Paid search, paid social, SEO, and a custom ROI Performance Dashboard connecting to CRM and MAP systems. The unified measurement model is their core pitch, budget decisions are made from revenue data, not channel-specific metrics.
3. CRO and landing page optimization Conversion rate testing on landing pages, forms, and CTAs specifically for B2B tech, where a small improvement in form conversion can move more pipeline than doubling traffic.

Notable clients and results

Note: Avid Demand's case studies use anonymous client descriptions. Named clients appear on their homepage but without published metrics.

What to look for when choosing a B2B SEO agency

Have they worked with companies like yours?

B2B SEO for a Series A SaaS company with a six-month enterprise sales cycle is a fundamentally different problem from B2B SEO for a manufacturer or a fintech platform. Check their case studies and look at whether the problems they solved, buyer persona, content type, conversion goal, sales cycle length, resemble yours. Logos on a homepage don't tell you that. Case study details do.

Do they understand the full visibility picture?

Any B2B SEO agency you evaluate in 2026 should have a clear answer to how they track and improve AI search visibility, not just Google rankings. LLMs are part of the B2B buyer research process now. How your brand appears in ChatGPT, Perplexity, and Google AI Overviews matters. If an agency's reporting stops at keyword rankings and organic sessions, that's a gap.

"Google is sending less and less traffic to the web every year, and in B2B, when people research products and services, LLMs are almost always part of that equation., Steve Toth, CEO, Notebook Agency"

Do they tie work to pipeline, not traffic?

Traffic is not a business outcome. A B2B SEO program should have a clear line from content to leads, pipeline, and closed revenue. Ask how they measure success, what their conversion rate benchmarks are for organic traffic in your category, and how they track lead quality from organic versus other channels. The best agencies on this list, Omniscient Digital, RevenueZen, Grow and Convert, all publish case studies with pipeline and revenue attribution, not just traffic numbers.

Does the engagement model match how you work?

Some agencies are retainer-only, others offer project-based entry points. RevenueZen publishes full pricing online. Avid Demand starts with a 90-day trial. Omniscient Digital requires a $10,000/month minimum. Obility publishes tiered pricing from $1,850 to $5,450 per month. Understand what you're committing to and who owns strategy versus execution before you sign anything. The mismatch between a client expecting senior involvement and getting junior account management is the most common reason B2B agency relationships end early.

Why Scale Theory works for B2B companies

Scale Theory is built for B2B SaaS companies, growth-stage to mid-market, where the team needs a fully managed program, not a content vendor.

We treat Google SEO and AI search visibility as one interconnected system. The authority signals that drive Google rankings are the same ones that drive LLM citations. There's no reason to run them separately.

Everything runs through one team: strategy, briefs, content production, editorial review, publishing, tracking, and reporting. You provide direction. We run the system.

ScaleX, our internal AI visibility tracker, monitors brand presence across ChatGPT, Perplexity, Gemini, and Google AI Overviews. It surfaces gaps, tracks how visibility shifts over time, and feeds back into what we prioritize, without adding an external tool to your stack.

Our four published case studies, EdisonOS (59x LLM session growth, $5.5M total pipeline), Gloroots (0 to 20+ LLM-sourced leads per month in four months), BQP (50 to 500 monthly LLM sessions in a deep-tech niche), and Flowcart (200+ monthly LLM sessions in four months), are among the most specific published LLM attribution results from any B2B SEO agency in the market.

If you want to see where your brand currently stands in Google and AI search and what it would take to close the gaps, book a 30-minute strategy call.

Frequently Asked Questions

What makes a B2B SEO agency different from a general SEO agency?

B2B buyers don't convert on the first visit. They research over weeks or months, involve multiple stakeholders, and compare options across Google, LinkedIn, AI tools, and peer networks before talking to sales. A B2B SEO agency understands how to build content for that kind of buying process, not just for traffic volume. That means BOFU content strategy, intent mapping tied to the sales funnel, and measurement that tracks leads and pipeline, not sessions.

How much do B2B SEO agencies typically charge?

It varies considerably. Scale Theory starts at $1,500 per month. RevenueZen publishes tiers from $3,000 to $15,000 per month. Omniscient Digital starts at $10,000 per month. Obility's Summit tier starts at $5,450 per month. First Page Sage benchmarks full-service campaigns at $10,000 to $15,000 per month. Most agencies on this list don't publish pricing and require a discovery call. A reasonable benchmark for a full-service B2B SEO program is $5,000 to $15,000 per month, depending on scope, execution depth, and whether the engagement includes technical SEO, content production, and link building.

Do B2B SEO agencies also handle AI search visibility?

Most agencies on this list have developed some form of GEO or AEO service. Siege Media, Grow and Convert, Omniscient Digital, Directive, Obility, and RevenueZen all have dedicated AI search practices. The depth varies: some treat it as a content formatting and schema exercise; others have built proprietary tracking tools (Grow and Convert's Traqer AI, Siege Media's BlueprintIQ, Obility's GEO dashboard, Scale Theory's ScaleX). Ask any agency you're evaluating how they specifically track and improve LLM citations, not just Google AI Overview appearances.

How long does B2B SEO take to produce results?

Most B2B SEO programs produce measurable keyword movement within three to six months and qualified pipeline within six to nine months. Compounding results, where organic becomes a primary lead channel, typically takes 12 to 18 months with consistent execution. The agencies with the best-documented case studies on this list (Omniscient Digital, Grow and Convert, RevenueZen, Scale Theory) all show meaningful pipeline results in the six to 18-month range.

Which B2B SEO agency is best for SaaS companies?

Several agencies on this list specialize in B2B SaaS: Scale Theory, Omniscient Digital, Grow and Convert, Siege Media, RevenueZen, and Directive all have documented SaaS results. For bottom-funnel, demo-focused content: Grow and Convert. For strategic organic growth tied to pipeline at the $10K+ budget range: Omniscient Digital. For integrated paid and organic from one team: Directive or Obility. For a first SEO program at growth stage with transparent pricing: RevenueZen. For Google + AI search built as one managed system: Scale Theory.

What is GEO and do B2B companies need it?

GEO (Generative Engine Optimization) is the practice of getting your brand cited in AI-generated answers from tools like ChatGPT, Perplexity, Gemini, and Google AI Overviews. B2B buyers increasingly use these tools during the research and evaluation phase, asking questions like "what's the best CRM for B2B sales teams" or comparing specific vendors before a demo call. If your buyers use AI tools to shortlist vendors (and most do), appearing in those answers matters. Every agency on this list either already offers GEO or is building toward it.
