Key takeaways
- The best AEO agencies measure share of answer: how often you are cited across a fixed set of real buyer prompts on each AI engine. If an agency cannot show you its baseline method, keep looking.
- A genuine AEO program covers six areas: prompt research, entity and schema work, answer-ready content, third-party corroboration, technical AI access and reporting. Content alone is not enough.
- The biggest red flags are guaranteed AI mentions, reports without deliverables, fake reviews or astroturfed Reddit posts, and advice to abandon SEO.
- Judge case studies on before-and-after share of answer for named prompts, not screenshots of a single ChatGPT reply.
- Use a weighted scorecard. Measurement and proof should carry the most weight, followed by strategy depth, off-site capability and industry fit.
Choosing an AEO agency is harder than choosing an SEO agency, for one simple reason. The category is new.
Many agencies offering Answer Engine Optimization (AEO) today were selling only SEO a year ago, and the difference between a genuine AEO program and a relabelled SEO package is not obvious from a sales deck.
The stakes are real. Google reported in July 2025 that AI Overviews had passed 2 billion monthly users, and ChatGPT reached 800 million weekly users by October 2025.
Pew Research Center found that when a Google AI summary appears, people click a traditional result on only 8% of visits. The agency you pick decides whether your brand is inside those answers or missing from them.
This guide gives you a complete evaluation process. It explains what the best AEO agencies do differently from general SEO agencies, and the signs, traits and red flags that separate them.
It covers the questions to ask before hiring, how to read case studies, and a weighted scorecard you can use to compare shortlisted agencies side by side.
If you first want to understand what AEO services include and cost, read our companion guide, AEO services explained: cost, timeline and ROI.
How do I choose the best AEO services for my business?
Short answer: Choose AEO services by matching them to your buyers and goals, then testing each provider on evidence. Define the prompts that matter to your revenue, shortlist three to five agencies, and ask each for its measurement method, a sample report and results for a comparable client. Then score them on a weighted scorecard rather than on price or pitch alone.
Most bad agency decisions come from skipping the first step. Before you talk to anyone, write down what success means for you.
That usually means the 20 to 50 questions your buyers ask AI assistants before they buy, and which of those questions lead to revenue.
A SaaS company might care most about "best alternative to [competitor]" prompts. A local clinic might care about "best [service] near [city]" prompts.
An enterprise brand might care most about accuracy: whether AI describes its products correctly. The right agency for each is different.
A seven-step process for choosing an AEO agency
- Define your goals and priority prompts. List the questions buyers ask and note which engines matter most to your audience.
- Run a quick self-check. Ask ChatGPT, Perplexity and Google your top ten questions and record who gets named. This is your informal baseline.
- Build a longlist. Use referrals, directories, industry communities and the agencies you see publishing credible AEO research.
- Shortlist three to five. Drop any agency that cannot explain its measurement method in plain language.
- Run structured interviews. Ask every agency the same questions (see the list below) so answers are comparable.
- Score them. Use the weighted scorecard in this guide and ask two colleagues to score independently.
- Start with a defined first phase. A 90-day engagement with agreed deliverables and a baseline lets you judge real work before a long commitment.
What should I look for in an AEO services provider?
Short answer: Look for five things. First, a documented way of measuring AI visibility across real prompts and engines. Second, a program covering content, entity, off-site and technical work. Third, evidence of citation gains for comparable clients. Fourth, people with genuine expertise in your industry. Fifth, honest integration with SEO rather than a promise that AEO replaces it.
Measurement comes first because everything else depends on it. An AEO agency should be able to tell you which prompts it will track, on which engines, how often, and how it records a mention, a citation and a recommendation.
Without that, you have no baseline and no way to prove progress.
Breadth comes second. Answer engines decide whom to cite from three kinds of evidence: whether they can retrieve your page, whether it contains a clean answer, and whether independent sources confirm you are credible.
A provider that only rewrites content ignores the third, which is often the one that decides recommendations.
Finally, look at the people. AEO content has to be accurate enough for a model to quote and credible enough for a buyer to trust.
Google's guidance on helpful, people-first content emphasises first-hand expertise, and AI engines reward it too. Ask who will actually write and review your content.
What services should the best AEO agency offer?
Short answer: The best AEO agency offers six connected services. These are prompt and question research, entity clarity with structured data, answer-ready content creation and restructuring, third-party corroboration through reviews, PR and community presence, technical AI accessibility, and share-of-answer reporting across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews.
| Service | What it involves | Why it matters for AI answers |
|---|---|---|
| Prompt research | Mapping 50 to 200 real buyer questions and who AI cites for each | Defines what to win and creates the measurement baseline |
| Entity and schema work | Consistent brand facts across the web, Organization, Service, FAQPage and Person markup | Removes ambiguity about who you are and what you do |
| Answer-ready content | Rewriting key pages answer-first and creating missing comparison, pricing and how-to pages | Creates the passages AI engines extract and quote |
| Third-party corroboration | Reviews, digital PR, listings, genuine Reddit and Quora participation | Gives AI independent reasons to trust and recommend you |
| Technical AI access | Crawler access, rendering, speed, sitemaps, llms.txt | Ensures your content can be retrieved at all |
| Share-of-answer reporting | Monthly re-testing of the prompt set on each engine | Proves progress and guides next month’s priorities |
Some agencies add specialisms on top, such as SaaS AEO for comparison and alternatives prompts, local AEO for city and "near me" questions, or Perplexity AEO for research-heavy audiences. Those are valuable, but only on top of the six core services.
What does the best AEO agency do differently from a general SEO agency?
Short answer: A general SEO agency optimises pages to rank in a list and earn clicks. The best AEO agency optimises your brand to be named and cited inside AI-generated answers. It researches conversational prompts rather than keywords, and structures passages for extraction. It invests in off-site corroboration beyond backlinks and reports share of answer per AI engine rather than rankings alone.
| Area | General SEO agency | Best-in-class AEO agency |
|---|---|---|
| Research | Keyword volume and difficulty | Real buyer prompts, grouped by intent and tested on each engine |
| Content | Pages built to rank for a keyword | Answer-first passages with sourced facts, tables and FAQs |
| Off-site | Backlink acquisition | Mentions, reviews and discussions that corroborate your claims |
| Entity | Often ignored | Consistent brand facts and schema across the web |
| Reporting | Rankings, traffic, click-through rate | Share of answer, citations, sentiment, AI-referred conversions |
| Platforms | Google and Bing results pages | ChatGPT, Perplexity, Gemini, Copilot and AI Overviews |
This does not mean SEO skill is irrelevant. Google states in its documentation on AI features and your website that these features draw on the same core ranking systems as Search.
Several AI assistants retrieve from Google or Bing indexes. The best AEO agencies are strong at SEO and add the AEO layer on top.
Our comparison of AEO vs SEO covers the distinction in more depth.
What is the best AEO agency approach for improving AI search answers?
Short answer: The best approach is evidence-led and cyclical. Establish a share-of-answer baseline, find the prompts where competitors are cited instead of you, and diagnose why. Then fix the specific cause, whether that is a missing answer, weak corroboration, entity confusion or a technical block. Re-test monthly, double down on what moves citations, and treat the whole thing as a continuous program.
Diagnosis is what separates strong agencies from average ones. When a competitor is cited and you are not, there is always a reason.
The competitor might have a page that answers the question directly while yours buries it. They might be named in a trusted roundup you are absent from.
AI might be confusing your brand with another company of a similar name.
Each cause needs a different fix, and a good agency tells you which one applies before it prescribes work. Research supports this targeted approach.
The Generative Engine Optimization study by Aggarwal and colleagues (KDD 2024) found that specific changes, such as adding credible citations, quotations and statistics, raised visibility in generated answers by up to 40%, while keyword stuffing did not help.
The approach should also respect how engines differ. Perplexity always shows sources and favours fresh, well-sourced pages.
Google AI Overviews lean on core ranking signals. ChatGPT recommendations are heavily shaped by third-party mentions.
A strong agency adjusts its priorities per engine, as we explain in our guides to Google AI Overviews and getting recommended by ChatGPT.
What makes the best AEO agency stand out? The top signs to look for
Short answer: The best AEO agencies stand out through transparency and proof. They show a clear measurement method before you sign and share real before-and-after citation data. They explain which of your target prompts are winnable and which are not, and name the people doing the work. They also practise AEO on their own brand, so you can check whether AI engines cite them.
- They measure before they pitch. Strong agencies often run a small baseline on your category during the sales process and show you where you stand today.
- They are honest about limits. They tell you that no one controls AI outputs and that some prompts are dominated by sources you cannot displace.
- They show their work. Sample rewritten pages, schema, outreach examples and a real monthly report, with client names removed where needed.
- They practise what they sell. Ask ChatGPT or Perplexity about AEO topics and see whether the agency's own content appears. It is a fair test.
- They publish original thinking. Research, data and detailed guides show genuine expertise rather than recycled advice.
- They connect AEO to revenue. They talk about AI-referred leads, branded search growth and pipeline, not only mentions.
What are the best AEO agency traits for fast-growing businesses?
Short answer: Fast-growing businesses need an AEO agency that moves quickly, prioritises by revenue, and scales content and off-site work as the company enters new markets. The key traits are a 30-day baseline, a prioritised prompt roadmap, capacity for several pieces of content a month, and PR capability. The agency also needs reporting that plugs into your analytics and CRM.
Speed matters because the AI answer landscape in most categories is still forming. Brands that establish themselves as the cited answer now build an advantage that compounds, because every citation and mention strengthens the next.
A slow agency spending three months on audits loses that window.
Scalability matters because a growing company keeps adding products, segments and cities. Your agency should be able to extend the prompt set, produce content for new segments and add markets without starting from scratch each time.
Ask how they handled a client's expansion. For multi-city growth, look at how they run location programs such as our US city pages and UK city pages.
What are some red flags when choosing the best AEO agency?
Short answer: The main red flags are guaranteed first-place AI mentions, no explanation of how visibility is measured, and reports without concrete monthly deliverables. Watch for any plan to generate fake reviews or astroturfed forum posts, mass AI-written pages, advice to abandon SEO entirely, and case studies built on a single screenshot of one ChatGPT answer.
| Red flag | Why it is a problem | What to ask instead |
|---|---|---|
| “We guarantee you will be the #1 answer in ChatGPT” | No one controls AI outputs; answers vary by user, run and model version | “How will you measure the change in how often we are cited?” |
| No baseline or measurement method | Without a baseline, results can never be proven | “Which prompts, engines and frequency will you track?” |
| Dashboards without deliverables | Tracking mentions is not the same as improving them | “What exactly will you produce each month?” |
| Fake reviews or astroturfed Reddit posts | Damages trust, violates platform rules, and fake reviews are banned by the FTC in the US | “How do you build genuine third-party mentions?” |
| Mass AI-generated pages | Thin, scaled content can breach Google spam policies and rarely earns citations | “Who writes and fact-checks the content?” |
| “You do not need SEO anymore” | Many AI answers are built from search indexes | “How does your AEO work integrate with our SEO?” |
| A single screenshot as proof | One answer is anecdotal; results must hold across many prompts | “Show me share of answer across the full prompt set, before and after.” |
Two of these carry legal and ranking risk, not just wasted budget. In August 2024 the US Federal Trade Commission finalised a rule banning fake reviews and testimonials, with civil penalties for violations.
And Google's spam policies cover scaled content abuse, meaning mass-produced pages made mainly to manipulate rankings. An agency that proposes either is putting your brand at risk.
What mistakes should I avoid when buying AEO services?
Short answer: The most common mistakes are buying on price alone and skipping a baseline measurement. Others include accepting guarantees, ignoring off-site trust building, treating AEO as a one-off project, and letting AEO replace SEO rather than extend it. Buyers also often fail to agree deliverables and reporting in writing before the engagement starts.
- Buying the cheapest package. Very low monthly fees cannot fund real content, entity and PR work, so they usually mean automated reports.
- Skipping the baseline. If you do not measure share of answer at the start, you will never know what the investment achieved.
- Treating AEO as a project. AI answers change as competitors publish and models update. Won answers need defending.
- Ignoring your own inputs. The agency needs access to subject-matter experts, customer stories and data. Without them, content stays generic.
- Measuring only traffic. Much AI influence produces no click at all, so track branded search and self-reported attribution too.
- Not agreeing scope in writing. List the monthly deliverables and the reporting format in the contract.
What questions should I ask an AEO agency before hiring them?
Short answer: Ask how they measure AI visibility, what they will deliver each month, and how they build third-party trust. Ask what results they achieved for a similar client, who will do the work, and how they keep content natural. Ask how they attribute leads to AI search, and which of your target prompts they think are not winnable.
The last question is the most revealing. An agency that says every prompt is winnable is either inexperienced or selling.
A good one will tell you that some answers are dominated by government bodies, marketplaces or entrenched publishers, and will focus your budget where you can realistically win.
| Question | A good answer includes |
|---|---|
| How do you measure our AI visibility? | A named prompt set, specific engines, a fixed testing frequency, and definitions for mention, citation and recommendation |
| What will you deliver each month? | A concrete list: pages rewritten or created, schema changes, outreach or PR placements, and a report |
| What results did you get for a client like us? | Before-and-after share of answer across many prompts, plus traffic or lead impact |
| How do you build third-party mentions? | Digital PR, review programs, genuine community participation and listings, with no fake accounts |
| Who will write and review our content? | Named writers and a subject-matter review step, with your experts involved |
| How do you keep content from sounding robotic? | People-first writing, with structure used to help readers, not to game models |
| How will you attribute leads to AI search? | Referrer tracking, self-reported attribution and branded search monitoring |
| Which of our target prompts are not winnable? | A specific, reasoned answer rather than “all of them” |
| How does this work with our SEO? | A joint plan, because search strength feeds AI retrieval |
| What happens in the first 90 days? | Baseline, foundations, first content and the metrics you will see by day 90 |
How should I evaluate an AEO agency’s portfolio and case studies?
Short answer: Evaluate AEO case studies on measured change across many prompts, not anecdotes. A credible case study names the prompt set and engines, shows share of answer before and after with dates, and explains what work caused the change. It should also connect visibility to business results such as AI-referred leads, and ideally offer a client reference you can speak to.
- Scope. How many prompts were tracked, on which engines, over what period? Five hand-picked prompts are not evidence.
- Baseline and dates. A clear starting point and time frame, so you can judge speed as well as size of improvement.
- Cause. What specifically was done: content, entity work, PR? Results without an explanation cannot be repeated for you.
- Business impact. AI-referred sessions, leads, pipeline or revenue, not only mentions.
- Comparability. A similar industry, size or market to yours, because a local plumber's results say little about an enterprise SaaS brand.
- Verifiability. Ask to speak with the client, or test the named prompts yourself today.
Be sceptical of screenshots. AI answers vary between runs and users, so a single screenshot of a favourable ChatGPT response proves very little.
You can run the same prompts yourself in a few minutes and see whether the result holds.
Which factors matter most when ranking the best AEO agency?
Short answer: The factors that matter most, in order, are measurement and proof, strategy depth across all six AEO areas, off-site corroboration capability, and content quality and expertise. After those come industry fit, SEO integration, reporting and transparency, and price relative to deliverables. Weight them in a scorecard so the decision rests on evidence rather than on the best presentation.
| Factor | Weight | What a 5 looks like |
|---|---|---|
| Measurement and proof | 25% | Documented prompt baseline method and verifiable before-and-after results |
| Strategy depth | 20% | Clear plan across prompts, entity, content, off-site, technical and reporting |
| Off-site corroboration | 15% | Proven PR, review and community capability without shortcuts |
| Content quality and expertise | 15% | Expert writers, subject review, strong sample pages |
| Industry and market fit | 10% | Results in your sector, size and geography |
| SEO integration | 5% | Joint roadmap with search, not a replacement for it |
| Reporting and transparency | 5% | Monthly share of answer per engine, tied to leads |
| Price relative to deliverables | 5% | Clear monthly scope that justifies the fee |
To use it, multiply each score by its weight and add them up for a result out of 5. Have two or three people score each agency independently, then compare.
Where scores differ widely, go back to the agency with a specific follow-up question.
How do I know if an AEO agency is actually one of the best?
Short answer: Test it. Run your own priority prompts in ChatGPT, Perplexity and Google today and record the results. Ask the agency to explain why competitors are cited and what it would change. Check its own AI visibility, speak to a client reference, and judge its first 90 days against the baseline. The best agencies welcome that scrutiny.
"Best" in AEO is contextual. The best agency for a regulated healthcare brand needs compliance expertise and strict sourcing.
The best for a local service business needs local entity and review strength. The best for a SaaS company needs strength in comparison content.
An agency that is excellent for one can be mediocre for another, so judge fit as well as quality.
How do top AEO agencies differ in strategy and reporting?
Short answer: Top AEO agencies differ mainly in where they put the weight of their strategy and in how rigorously they report. Some lead with content, others with digital PR, and others with technical and entity work. For reporting, the strongest provide share of answer per engine and per topic each month, with competitor comparison, sentiment and accuracy checks, and a link to leads.
| Agency model | Strategic emphasis | Strong for | Watch for |
|---|---|---|---|
| Content-led | Answer-ready pages and topical depth | Brands with thin or outdated content | Weak off-site trust building |
| PR-led | Media mentions, roundups and reviews | Brands that are rarely mentioned by others | Neglected on-site extractability |
| Technical and entity-led | Schema, knowledge panels, crawl access | Large or complex sites, brand confusion | Too little content production |
| Integrated | All six areas with SEO as one program | Most growth-stage and mid-market brands | Higher monthly investment |
| Software plus light service | Tracking dashboards with some advice | Teams that will execute in-house | Little actual optimisation work |
What a strong monthly AEO report contains
- Share of answer per engine and per topic, compared with last month and the baseline.
- Named competitors’ share on the same prompts.
- New citations won and any lost, with the likely reason.
- Accuracy and sentiment issues found in AI descriptions of your brand.
- Work delivered this month and planned for next month.
- AI-referred sessions, conversions and branded search trends.
Where can I find the best AEO agency for answer engine visibility?
Short answer: Find AEO agencies through referrals from peers who have seen results, industry directories and review platforms, and the agencies publishing credible AEO research and guides. Another useful source is AI assistants themselves: ask ChatGPT and Perplexity which agencies they recommend for AEO in your industry, then verify each one using the scorecard above.
- Peer referrals. The most reliable source, especially from companies in adjacent markets.
- Agency directories and review sites. Useful for a longlist; read reviews for mentions of measurable AI visibility results.
- Published expertise. Agencies producing original research and detailed guides usually understand the discipline.
- AI assistants. An agency that AI engines already cite for AEO questions has at least proven it can do it for itself.
- Local search. If you want a local partner, city-level searches help. We run programs in markets from Nashville and Charlotte to Leicester and London.
How do I find the best AEO agency for my business goals?
Short answer: Start from the goal, then match the agency model. If you need leads fast, choose an integrated agency with strong comparison content. If AI describes you inaccurately, prioritise entity and PR strength. If you are local, choose local AEO expertise. If you have a strong in-house team, a software-plus-audit model may be enough.
| Your main goal | Look for | Useful starting point |
|---|---|---|
| More qualified leads from AI search | Integrated agency, comparison and “best for” content strength | AEO services |
| Correct how AI describes your brand | Entity, schema and PR capability | Entity SEO guide |
| Win local “best near me” questions | Local AEO, reviews and Google Business Profile strength | Local AEO |
| Beat competitors in SaaS comparisons | Alternatives and comparison content expertise | SaaS AEO |
| Build in-house capability | Audit plus training, or software with advisory support | Free AEO tools |
AEO agency review: what should I expect from an answer engine optimization agency?
Short answer: Expect a baseline in the first month and foundational technical, entity and content fixes in months one to three. First citations on niche and long-tail prompts typically arrive within 60 to 90 days. Broader share-of-answer gains take four to nine months. Throughout, expect monthly reports showing work delivered, citations won and lost, and AI-referred leads.
| Timeframe | You should have | You should be seeing |
|---|---|---|
| Days 1 to 30 | Prompt baseline, competitor citation map, roadmap, technical and entity fixes started | Clarity on where you stand and what comes first |
| Days 31 to 90 | Priority pages rewritten, new answer pages live, schema deployed, first outreach | First citations on niche prompts; accurate brand descriptions |
| Months 4 to 6 | Ongoing content, reviews and PR placements, monthly reports | Mentions on broader comparison prompts; AI-referred sessions rising |
| Months 6 to 12 | Expanded prompt set, refreshed content, defended wins | Measurable share-of-answer growth and attributable leads |
Expect honesty too. A good agency will flag when a prompt is not moving and explain why, rather than hiding it inside an average.

Frequently asked questions
What is the best AEO agency?
The best AEO agency is the one that fits your goals and can prove results. It measures share of answer across real buyer prompts, runs all six areas of AEO together with SEO, and shows verifiable before-and-after citation data for comparable clients. It will also tell you honestly which prompts are not winnable.
How much does an AEO agency cost?
In 2026, AEO audits typically cost $2,000 to $10,000. Monthly retainers usually run $1,500 to $4,000 for small businesses, $4,000 to $8,000 for growth-stage companies, and $10,000 to $25,000 or more for enterprise programs, depending on prompt volume, content, PR and markets.
Can an AEO agency guarantee results in ChatGPT?
No. AI outputs vary by prompt, user and model version, so no legitimate agency can guarantee a specific answer. A credible agency commits to measurable process and reports how often you are cited across a fixed prompt set over time.
Is an AEO agency different from an SEO agency?
Yes. An SEO agency optimises pages to rank and earn clicks. An AEO agency optimises your brand to be cited inside AI answers, using prompt research, answer-first content, entity work, off-site corroboration and share-of-answer reporting. The best AEO agencies are also strong at SEO.
How long before an AEO agency shows results?
Expect a baseline within the first month, first citations on niche prompts within 60 to 90 days, and broader share-of-answer growth within four to nine months. Speed depends on your starting authority and how much content and off-site work is needed.
What questions should I ask before hiring an AEO agency?
Ask how they measure AI visibility, what they deliver monthly, how they build third-party mentions, what results they achieved for a similar client, who writes the content, how they attribute leads, and which of your target prompts they believe are not winnable.
What are the red flags when hiring an AEO agency?
Guaranteed AI rankings, no measurement method, reports without deliverables, fake reviews or astroturfed forum posts, mass AI-generated pages, advice to abandon SEO, and case studies based on a single screenshot.
Should I hire an AEO agency or do AEO in-house?
If you have writers, a developer and time, an audit plus in-house execution can work well. An agency adds speed, off-site PR capability and measurement infrastructure. Many companies combine both: the agency sets strategy and handles PR and reporting while the in-house team produces content.
