What Is an AEO Agency? Services, Questions to Ask and Red Flags

An AEO agency is a marketing firm that helps a business appear, and appear correctly, inside answers written by AI systems. Where a classic SEO agency is judged on positions in a list of links, an AEO agency is judged on whether ChatGPT, Perplexity, Claude, Gemini or Google's AI features mention the brand when a buyer asks a relevant question, what they say about it, and which pages they cite as evidence. If the term itself is new to you, start with our guide to answer engine optimization.

The category is real but young. Google's own page on whether you need an SEO now lists "optimizing for generative AI" among the useful services that agencies and consultants provide, next to content development, keyword research and technical advice. That placement is telling: in practice most AEO agencies are SEO agencies that added AI visibility work, and the best of them treat the two as one program rather than separate products.

Service menus vary, but the work clusters into a handful of jobs. Some are the same tasks an SEO firm has always done, pointed at a new audience of machines. Others exist only because AI systems assemble answers from many sources and can misdescribe a brand that never published a clear statement about itself. When you read a proposal, map each line item to one of the jobs below, and ask which ones you are paying for and which are already handled by your team.

A sensible engagement starts with measurement, not content. The agency should first document how each engine answers your category's questions today, because that baseline is the only way to prove later that anything changed. Expect a list of prompts, the answers collected, the sources each engine cited, and a short diagnosis of why competitors are named and you are not.

The second phase is usually technical. AI companies run several crawlers with different jobs, and blocking the wrong one can quietly remove you from answers. OpenAI's crawler documentation notes that each setting is independent: a site can allow OAI-SearchBot to appear in search results while disallowing GPTBot so its content is not used for training. Perplexity's crawler page says PerplexityBot surfaces and links websites in Perplexity results and is not used to crawl content for AI foundation models. A competent agency explains these choices to you rather than flipping switches.

After that come content and off-site work, which take longest, followed by a recurring report. Ask for the cadence up front, since AI answers change from week to week and a single snapshot proves little.

Not every business needs an agency. Google says plainly that if you run a small local business, you can probably do much of the work yourself, and the same logic applies to AEO, because most of the work is clear writing, accurate structured data and consistent brand facts. Our DIY plan for SEO and AEO shows what that looks like week by week.

An agency earns its fee when you lack the hours, when the site is large or technically complex, or when you need earned media in publications you cannot reach alone. A tool is the cheapest of the three and answers a narrower question: where do you stand, and is it improving? Many teams combine them, running the work in-house or through an agency and using an independent tool to check the results. Costs vary widely with scope, so compare proposals by the deliverables listed rather than by the label on the retainer.

Google's advice on hiring an SEO is a good template here, and two of its suggested interview questions carry straight over: what kind of results do you expect to see, and in what timeframe, and how do you measure your success? The same page recommends that you only grant read access to Search Console during an audit, not write access. Add the AEO-specific questions below, and pay attention to how concretely each one is answered. A firm that has done this work will talk about prompts, engines and sources. A firm that has only renamed its SEO package will talk about keywords and rankings.

The first red flag is a guarantee. No one controls how an AI model phrases its answer, and Google's SEO starter guide says that there are no secrets that will automatically rank a site first. An agency that promises a set number of ChatGPT citations is promising something it cannot deliver.

The second is a secret formula. Google's documentation on AI features and your website says that to appear as a supporting link in AI Overviews or AI Mode a page must be indexed and eligible to show with a snippet, and that there are no additional technical requirements. Proprietary "AI ranking hacks" deserve skepticism.

The third is scale without substance. Google's guidance on AI-generated content says that using automation, including AI, to generate content with the primary purpose of manipulating ranking in search results is a violation of its spam policies. Hundreds of thin pages written to catch prompts put your whole domain at risk.

The fourth is manufactured reputation. In August 2024 the U.S. Federal Trade Commission announced a final rule banning fake reviews and testimonials that lets it seek civil penalties against violators. Any plan to seed reviews or forum posts under fake identities is a legal risk, not a visibility tactic.

Whether you hire an agency or not, you should own your own measurement. Some of it is free: Google Search Console is a free service that helps you monitor, maintain and troubleshoot your site's presence in Google Search, and Microsoft's AI Performance report in Bing Webmaster Tools shows how often your content is cited in generative answers across Copilot and Bing's AI summaries.

For the other engines, the AEO Grader free scan gives you a starting point in about a minute: an AEO score with a four-pillar breakdown, one grounded Gemini and Google Search check, an action plan with code snippets, and a competitor and sentiment snapshot. Its per-engine view is an estimate. When you need hard evidence, the $10 full report asks real buyer questions to ChatGPT, Claude, Perplexity and Gemini live and shows each engine's actual answer with sources, your share of voice against competitors and a prioritized fix list. Run it before an agency starts and again later, or use monthly tracking at $9 per month for a fresh four-engine report each month. It complements an agency's own reporting rather than replacing it, and it does not guarantee rankings or citations. Our methodology page explains how scores are calculated, and our guide to measuring AEO covers which numbers to watch.
