Answer Engine Optimization Agency, Measured Prompt by Prompt
Answer engine optimization (AEO) is the work of getting your business named, cited and described accurately when buyers ask ChatGPT, Perplexity or Google's AI Overviews and AI Mode who to hire. CFS Marketing does that work as a monthly engagement, and we measure it the same way every month: a fixed set of your buyers' real questions, run by hand in named engines, scored and dated. You see exactly which answers you are in, which ones you are not, and who is in them instead.

01
What Is Answer Engine Optimization (AEO)?
Answer engine optimization is improving the odds that AI answer engines mention, cite or recommend your business when someone asks a question your business can answer. Generative engine optimization (GEO) and "AI SEO" are other names for the same job. The labels differ by vendor; the work does not.
AEO overlaps heavily with SEO, and we treat it that way. Google says there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary. A page has to be indexed and eligible to show with a snippet, and even then, Google states that indexing and serving are not guaranteed. Google also says both features may use "query fan-out," running several related searches across subtopics to build one answer. That is why a single strong page rarely wins on its own. Your site needs clear answers across the questions around the one the buyer typed.
What AEO adds to SEO is mostly in two places:
- How results are measured. An AI answer is not a ranked list. You check what the engine says, question by question, and record whether you are in it.
- Where the work happens. ChatGPT and Perplexity run their own searches and often cite directories, review sites, "best of" lists and forum threads. Being named on the pages the engines read matters as much as your own site.
If your SEO is weak, fix that first or in parallel. AEO built on a site that search engines cannot crawl or trust does not hold.
02
What Does an Answer Engine Optimization Agency Actually Do?
An answer engine optimization agency fixes the reasons AI engines skip your business, in the order that should move your answers fastest. At CFS Marketing that work falls into five workstreams.
1. Crawler access
We confirm that the crawlers behind AI search can reach and read your money pages. That means checking robots.txt rules, CDN and firewall bot settings, and whether your page copy is in the HTML or only appears after JavaScript runs. This matters more than it sounds:
- OpenAI says sites that opt out of OAI-SearchBot will not be shown in ChatGPT search answers. Its separate GPTBot crawler is for model training. Blocking one is not the same as blocking the other, and plenty of robots.txt files get this wrong.
- On July 1, 2025, Cloudflare announced it was changing its default to block AI crawlers. One CDN setting can lock AI search out of a site that ranks well on Google.
If you block AI training crawlers on purpose, we note it and leave that decision with you.
2. Entity consistency
We make sure your business is described the same way everywhere the engines look: your website, your Google Business Profile, your directory listings, your social profiles and your Organization schema. Same name, same address, same services, same founder, same category. When those sources disagree, an engine has less reason to trust any of them, and it is more likely to describe you wrongly or not at all.
3. Answer-first content
We rewrite your money pages so each section opens with a direct answer to one buyer question, in plain language, with the specific detail a buyer needs (who it is for, what it includes, how it works, where you operate). Where a buyer question has no page on your site to answer it, we build one. Long introductions and slogans give an engine nothing to quote.
4. Schema, where the evidence supports it
We add structured data (Organization, Service, LocalBusiness, Person, BreadcrumbList and others) where it describes your business accurately and where the pages that win your answers use it. Google is clear that no special schema is needed to appear in AI features, and that structured data should match the visible text on the page. So we treat schema as a way to state facts cleanly, not as a trick, and we never mark up content that is not on the page.
5. Third-party mentions, lists and reviews
We work on the sources the engines already cite for your questions. Our measurement shows which directories, "best of" lists, review platforms and industry sites own your answers. From there the work is practical: correct and complete your listings, earn a place on relevant lists through legitimate outreach, and help you build a steady flow of genuine customer reviews. We do not buy fake reviews or pay for placement on lists that hide it.
03
How Do You Measure AEO Results?
CFS Marketing measures AEO with a fixed set of buyer questions, run by hand in named engines under clean conditions, scored the same way every time and dated. It is the same method as our AI Visibility Audit, so your first score and every later one can be compared directly.
| Element | How we do it |
|---|---|
| Fixed prompt set | 15 questions your buyers ask: 10 "money" questions asked right before someone hires, 5 brand questions. You approve the list. It stays fixed, so changes in your score come from the engines, not from us swapping questions. |
| Named engines | ChatGPT (search on), Google AI Overviews and AI Mode, and Perplexity. The same three every month. |
| Clean conditions | A fresh ChatGPT chat for every question, an incognito Google window set to your market, Perplexity logged out. We never lead an engine toward your name. |
| Repeated runs | Checks are spread over two days, because answers vary with time and between runs. If an answer changes between runs, we score the worse one. |
| Mention vs citation vs recommendation | Each answer is scored 0 to 3: absent, named in the text, cited as a linked source, or recommended as the pick. A citation is worth more than a mention, and a recommendation more than both. |
| Dated and kept | Every score is tied to the date, the exact question and the engine. If a check could not be run, its cell stays empty and the report says so. |
Every month we re-run the same questions and report the score next to the work we shipped. Where you share lead data, we also report enquiries that arrive from AI engines, alongside your conversion tracking, so AI visibility is judged by leads as well as by answers.

How Does an AEO Engagement with CFS Marketing Start?
An AEO engagement with CFS Marketing starts with the AI Visibility Audit, because nobody should pay for AI search work without a baseline. The audit is free and delivered by Cesar personally, after he reviews every answer by hand. It gives you a score out of 100, a table of who owns the answers you want, an AI crawler access check and your top three fixes.
- AI Visibility Audit. Baseline score, competitor table, access check, top three fixes.
- Written plan. The workstreams above, ranked by how fast they should move your score, with the pages and sources each fix touches.
- Monthly work. Access fixes first, then entity cleanup, then answer-first pages and schema, with third-party work running alongside. You approve anything published under your name.
- Monthly re-run and report. Same questions, same engines, same scoring. What moved, what did not, and what we change next.
AEO usually runs alongside SEO, since the same pages do both jobs. For businesses already buying traffic, it can sit next to our Google Ads management as well. Work runs on a monthly retainer scoped to the fixes you need, and Cesar quotes after reviewing your accounts.
05
What Won't CFS Marketing Claim About AI Search?
CFS Marketing will not claim results we cannot measure, or results that only the engines control. Several things commonly sold in this market fail that test.
- No guaranteed AI citations or recommendations. The engines choose their own sources, and their answers change from run to run. Anyone who guarantees that ChatGPT will recommend you is promising something they do not control. We commit to an honest score, the fixes most likely to move it, and a monthly re-run that shows whether they did.
- No llms.txt as a billed service. Google says you do not need to create new machine-readable files or AI text files to appear in its AI features. If you want an llms.txt file, we will add it as part of normal site work. We will not sell it to you as AI optimization.
- No promises of FAQ rich results. Since August 2023, Google has said FAQ rich results are shown only for well-known, authoritative government and health websites. We still write FAQs, because buyers and engines read them. We do not sell them as a route to extra space on Google.
- A single screenshot is not a result. One answer, from one run, on one day, proves that something appeared once. It does not prove it appears reliably. That is why we score repeated runs, keep the worse result, and date everything.
- No invented scores. If we did not see an answer, we do not score it.

Is Answer Engine Optimization Right for Your Business?
Answer engine optimization is right for your business if your buyers research before they call and you can sustain a monthly retainer. It fits best when:
- You sell a considered service, the kind people compare before hiring: legal, healthcare, home services, B2B and SaaS, real estate and professional services. (See the industries we work in.)
- You rank on Google but do not know what AI tools say about you.
- A competitor keeps coming up as "the one ChatGPT recommended."
- You can share lead data, so AI visibility can be tied to enquiries, not just answers.
It is not a fit if you want a guaranteed AI placement, a one-off schema install sold as a strategy, or a dashboard without anyone acting on it.

Answer Engine Optimization FAQ
The plan quiz takes about a minute, and you only share an email at the end.
Get my custom planWhat is an answer engine optimization agency?
An answer engine optimization agency improves how often and how accurately AI answer engines such as ChatGPT, Perplexity and Google's AI Overviews name, cite or recommend a business. CFS Marketing does this through crawler access fixes, entity consistency, answer-first content, accurate schema and work on the third-party sources the engines cite, measured monthly on a fixed set of buyer questions.
What is the difference between AEO and GEO?
AEO (answer engine optimization) and GEO (generative engine optimization) describe the same work: earning mentions and citations in AI-generated answers. Some agencies use GEO for ChatGPT-style tools and AEO for Google's AI features, but the methods overlap almost entirely. CFS Marketing uses both terms and measures both the same way.
Is AEO different from SEO?
AEO is built on SEO and shares most of its work: crawlable pages, clear content, accurate structured data and a trusted business name. Google says there are no special optimizations needed for AI Overviews and AI Mode beyond normal SEO best practices. AEO differs in how it is measured (answer by answer, not by ranking position) and in how much weight it puts on third-party sources such as lists, directories and reviews.
Can you guarantee my business will appear in ChatGPT?
No. No one can guarantee that ChatGPT or any other AI engine will mention or recommend a business, because the engines choose their own sources and their answers change. CFS Marketing commits to an honest baseline, the fixes most likely to improve it, and a monthly re-run on the same questions that shows whether they did.
How do you measure AEO results?
CFS Marketing measures AEO with 15 buyer questions run by hand in ChatGPT, Google AI Overviews and AI Mode, and Perplexity under clean conditions. Each answer is scored 0 to 3 (absent, named, cited or recommended), runs are repeated and the worse result is kept, and every score is dated. The same questions are re-run every month.
Do I need an llms.txt file?
You do not need an llms.txt file to appear in Google's AI features; Google says no new machine-readable or AI text files are required. CFS Marketing can add one as part of routine site work if you want it, but we do not sell it as an AEO service.
How much does answer engine optimization cost?
AEO work runs on a monthly retainer, scoped after the AI Visibility Audit shows what needs fixing, and Cesar quotes after reviewing your accounts. The audit itself is free, a separate, fixed-scope project that Cesar delivers personally.
