How to Choose the Best AEO & GEO Agency in 2026

AEO is new enough that most agencies claiming expertise in it are repackaging standard SEO services. Choosing the wrong one wastes budget at exactly the moment when getting AI visibility right matters most.

This guide covers 10 things to check and 10 questions to ask before hiring an AEO/GEO agency, so you can tell the real from the rebranded.

Scale Theory is included in this guide. The criteria below apply to any agency, including ours.

Top 10 things to check before choosing an AEO/GEO agency

Ten factors that separate agencies doing real AEO/GEO work from those selling the name.

1. AI search expertise

What it is

AEO is not Google optimization with a different label. Real AEO/GEO work means getting your brand cited in ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews, each of which pulls from different signals.

How to evaluate

Ask which specific AI platforms they optimize for and how their approach differs across each. An agency that lumps them all together and gives you one generic answer doesn't understand how these platforms work. ChatGPT and Perplexity don't weight signals the same way Google does, and a good agency knows this.

What the answer tells you

If the answer stays at the level of "we optimize for AI search," that's not an answer. You want specifics: which platforms, which signals, and how they track performance on each.

2. Proven results & case studies

What it is

This market is full of agencies that have adopted AEO/GEO terminology without the results to back it up. The only honest proof is demonstrated AI visibility improvement, referral traffic from AI platforms, or pipeline growth tied to AEO work.

How to evaluate

Ask for case studies that show citation share of voice improvements, not traffic growth or keyword rankings. Ask whether they can show you their clients appearing in AI-generated answers. If they can't, the work isn't there. See what companies winning in AI search actually look like as a benchmark.

What the answer tells you

Traffic up, domain rating up, keyword rankings improving, those are SEO metrics dressed as AEO success. The real signal is whether their clients appear in AI-generated answers for queries relevant to their business.

3. Entity SEO & Knowledge Graph expertise

What it is

LLMs don't just read pages, they build a model of what your brand is, what it does, and who it's for. Entity optimization is how you shape that model. It's distinct from keyword targeting, and most SEO agencies don't do it.

How to evaluate

Ask how they define and structure brand entities, facts, products, relationships, and attributes, so AI models associate your brand with the right topics. Ask specifically about Knowledge Graph presence. Understanding how to control brand narrative in LLMs is a specific skill, not a byproduct of good content. An agency that defaults to keyword research when you ask about entities hasn't made the shift.

What the answer tells you

Entity work requires a different skill set than traditional SEO. If the conversation keeps drifting back to keywords and content volume, they're not there yet.

4. Technical SEO & schema markup

What it is

Structured data is one of the most direct signals you can send to AI models. Schema markup, semantic HTML, and machine-readable content all help LLMs parse what your brand is and what it does. Without this, the rest of the AEO work is harder to land.

How to evaluate

Ask what schema types they implement and why. Ask about semantic HTML, not just whether they use it, but how they decide what to mark up. Ask about crawlability for AI bots specifically. A good agency will ask about your tech stack before making recommendations. One that jumps straight to answers hasn't asked enough questions.

What the answer tells you

Agencies that treat schema as a checkbox, adding basic Organization or Article markup and calling it done, are missing the depth that actually moves the needle for AI retrieval.

5. Content strategy for AI

What it is

Content written to rank on Google is not the same content that gets cited in AI answers. AEO content needs to be answer-first, structured for extraction, and built around the questions your buyers actually ask AI platforms. Keyword-focused blogs optimized for search volume don't perform the same way.

How to evaluate

Ask how they structure content for AI retrieval, specifically how they format answers so LLMs can extract and cite them. Ask whether they do topical mapping based on buyer prompts rather than just search volume. The AI SEO checklist for SaaS startups shows what the right content approach looks like at each stage. If the answer is "we write long-form, comprehensive content," that's not an AEO content strategy.

What the answer tells you

AEO content is structured differently from SEO content. If the agency's content approach sounds like it could have been written in 2018, it probably was.

6. Authority & AI citation building

What it is

LLMs cite sources they trust. That trust is built off-site, through brand mentions on authoritative third-party platforms, Digital PR, and citations from publications and databases that AI models consistently pull from. Backlinks help Google. Off-site citations are what help AI platforms.

How to evaluate

Ask which third-party platforms they target for citation building. Ask how they approach Digital PR specifically for AI visibility. Understanding how to talk about competitors in AI-indexed content and which pages control brand narrative are both part of real citation work. An agency with a backlink-only off-site approach hasn't made the transition.

What the answer tells you

If their off-site strategy is "build high-quality backlinks," that's SEO. AEO off-site work is about getting your brand mentioned in the right places so AI models learn to treat it as a trusted source.

7. AI-specific reporting & KPIs

What it is

Traditional rank tracking tells you nothing about AI visibility. The agencies that understand AEO have built or adopted infrastructure to track citation share of voice, AI referral traffic, and how often their clients appear in AI-generated answers.

How to evaluate

Ask exactly how they track AI visibility. Ask about server-side tracking, analysing server logs and URL parameters to identify AI bot traffic. If they don't ask about your hosting setup or analytics configuration early, that's a sign. The honest answer on attribution will acknowledge that clean per-query attribution is still difficult, and that directional data is the realistic starting point.

What the answer tells you

Agencies that promise precise attribution from AI channels from day one are overpromising. Agencies that report on DA, DR, or keyword rankings as their primary AEO metrics are doing SEO.

8. Industry experience

What it is

AEO strategy isn't generic. The queries your buyers ask AI platforms, the platforms they use, and the citation sources that matter to your category all vary by industry. An agency with no experience in your niche will have a learning curve at your expense.

How to evaluate

Ask whether they've worked with companies in your space, SaaS, healthcare, e-commerce, finance, or wherever you operate. Ask what's different about AEO in your category. Ask for relevant case studies. If the answer is "we work across industries," ask what they've learned that's specific to yours.

What the answer tells you

Generic answers to niche questions are a sign the agency will be learning on your budget. Industry-specific answers signal they've already done the work.

9. Transparent deliverables & roadmap

What it is

AEO is still evolving and a lot of agencies use that as cover for vague scopes and undefined timelines. The good ones can tell you exactly what they'll deliver, when, and how you'll know it's working, even accounting for the genuine measurement challenges.

How to evaluate

Ask for a sample deliverables breakdown for the first 90 days. Ask how they handle a content refresh versus new content creation in the early phase. Ask what the reporting cadence looks like and who owns it. Specifics, not generalities.

What the answer tells you

Vague scope is how agencies protect themselves when results are slow. Specific deliverables, even with honest caveats about measurement, are how agencies build trust.

10. Pricing & long-term strategy

What it is

AEO is a fast-moving space. Many agencies are still building their methodology in real time. Locking into a 12-month contract before seeing how they work is an unnecessary risk.

How to evaluate

Ask whether they'll do a 30–60 day paid pilot before committing to a full retainer. A pilot should cover at minimum: a baseline entity audit, citation share of voice measurement, and reoptimization of existing pages for AI retrieval. Ask how pricing scales and what happens if the methodology needs to change as the space evolves.

What the answer tells you

Agencies confident in their work are willing to prove it on a smaller scope first. Agencies that push straight to an annual contract before you've seen their execution are protecting their revenue, not your results.

Top 10 questions to ask before hiring an AEO/GEO agency

Take these into any sales call. The quality of the answers will tell you more than any pitch deck.

1. What is your AEO/GEO strategy, and how is it different from traditional SEO?

Listen for specificity. A real answer names the distinct technical levers, entity architecture, structured data, off-site citation building, server-side AI traffic tracking, and explains how they interact. A weak answer describes "AI-optimized content" and "comprehensive SEO" without drawing a clear line between the two. If they can't explain the difference, the difference probably doesn't exist in their actual work.

2. Which AI search platforms do you optimize for, ChatGPT, Gemini, Perplexity, Claude, Google AI Overviews?

Every serious AEO agency should be able to answer this across all five platforms, with a clear explanation of how each works and where the approaches diverge. Gemini pulls heavily from Google's entity graph. Perplexity cites third-party sources directly. ChatGPT is trained on different data. An agency that treats them as one uniform channel hasn't gone deep enough.

3. Can you share AEO/GEO case studies with measurable business results?

Push past traffic and ranking metrics. You want to see citation share of voice improvements, AI referral traffic data, or pipeline growth tied to AEO work. Screenshots of clients appearing in AI-generated answers for relevant queries are a strong signal. If they can only show SEO metrics and relabel them as AEO results, that tells you what the work actually is.

4. How do you improve entity authority and Knowledge Graph presence?

Good answers describe the process: how they define brand facts and relationships, how they structure them for AI model comprehension, and how they work to ensure the brand is correctly represented in Google's entity graph. Weak answers drift toward content volume and keyword targeting. Entity work is technical and specific, vague answers mean they're not doing it.

5. What technical optimizations do you implement, schema, semantic HTML, crawlability?

Ask for their schema implementation checklist and the specific types they prioritize for your category. Ask how they test crawlability for AI bots, not just Google's crawler. A good agency will ask about your CMS and hosting before answering this, because the right technical approach depends on your setup, not a standard template.

6. How do you earn AI citations and build brand authority across the web?

You're looking for a specific platform-targeting strategy: which review sites, industry publications, and data aggregators they work with, and why those platforms matter for AI retrieval in your category. "We build high-quality backlinks and do PR" is an SEO answer. An AEO answer names the specific sources LLMs consistently pull from in your space.

7. Which KPIs do you track, and how do you measure AI search success?

Good metrics: citation share of voice, AI referral sessions, brand appearance rate in target prompts, bottom-of-funnel prompt visibility, and pipeline influence. Weak metrics: domain authority, keyword rankings, and organic traffic growth without AI-specific segmentation. Ask whether they can show you what this reporting looks like in practice, ideally with a sample dashboard or past client report.

8. How do you track AI referral traffic, leads, and conversions?

This is where you'll find out whether they understand the technical realities of AEO measurement. The honest answer involves server-side tracking, URL parameter analysis, and directional data, because clean per-query attribution from AI channels doesn't exist yet. If they promise a precise attribution model from day one, that's not an honest answer.

9. What deliverables can I expect in the first 3–6 months?

Ask for a breakdown by month. Month one should cover entity audit, baseline citation measurement, and technical fixes. Months two and three should have content and off-site work underway. By month six, you should have directional data on citation share of voice movement and early AI traffic signals. If they can't give you a month-by-month breakdown, the work isn't scoped yet.

10. How will your AEO/GEO strategy integrate with my existing SEO and content marketing?

The right answer: they treat Google SEO and AI search as one unified system, because your buyers don't distinguish between them. The wrong answer: they treat AEO as a separate workstream that gets added on top of existing SEO. That approach creates duplication, mixed signals, and wasted spend. Integration isn't optional, it's how the work compounds.

Why should you consider Scale Theory's AEO/GEO services?

Scale Theory is an AI-driven organic growth agency working with B2B SaaS, tech, data, and AI companies. We build visibility systems across Google, LLMs, and AI-driven search, through entity architecture, content built for AI retrieval, and off-site citation building. Our clients range from growth-stage startups to mid-market companies, typically led by founders, CMOs, or heads of marketing who need AI visibility built into their organic strategy from the start, not added on later.

We work with EdisonOS, Gloroots, QuantumDesk, Flowcart, and BQP, among others. Each one operates in a different category with a different ICP. The strategy in each case was built around their specific buyers, not a template applied across clients.

What we've delivered

Flowcart, an AI-powered conversational commerce platform, came to us with a new domain and no organic presence after migrating from their previous brand. Five months later: 700+ monthly organic clicks, 12 of 20 target keywords ranking in the top 3, and 200+ monthly LLM sessions within four months. The LLM sessions are compounding as the entity and citation work matures.

QuantumDesk saw strong AEO/GEO visibility in 90 days. The brand now appears in Google AI Overviews, ranks in Google AI Mode for high-intent customer support queries, and gets referral traffic from ChatGPT, Gemini, Perplexity, and Claude. The work that got them there: AI-optimized content, structured data, topical authority, and citation-friendly pages that gave AI platforms a clear reason to surface the brand.

How we work

Every engagement starts with your business, product, ICP, buyer journey, competitive positioning. The AEO/GEO strategy follows from that, not from a standard playbook. We treat Google SEO and AI SEO as one system, because your buyers move between Google, ChatGPT, and Perplexity without drawing a distinction. We build both channels simultaneously, with measurement infrastructure that tracks what actually matters, citation share of voice, AI referral traffic, and pipeline influence.

Frequently asked questions

What does an AEO agency actually do?

An AEO agency optimizes your brand to be cited as a source in AI-generated answers, on platforms like ChatGPT, Perplexity, Gemini, and Google AI Overviews.

That means building entity architecture so AI models understand what your brand is, securing citations on the third-party sources LLMs pull from, and tracking your share of voice in AI-generated responses for the questions your buyers are asking.

How do I know if an AEO agency is legitimate?

Check if their own brand gets cited in AI answers for queries relevant to their category. Run the prompts yourself before the first call.

Beyond that, ask for case studies showing citation share of voice improvements, not traffic growth or keyword rankings. Ask how they track AI visibility and whether they can explain their retrieval methodology in plain terms. Vague answers to specific questions are the clearest signal available.
