Free tool / AEO Checker
Enter a page address to check the things that help Google's AI Overviews, ChatGPT, Perplexity and other answer engines read, trust and quote it: crawler access, indexing, text in the HTML, headings, a short opening answer, structured data and clear business facts. It checks readiness, not results, so it can't tell you whether an AI assistant mentions you today.
Free, with no sign-up and no email.

The guide
| Check | Why it matters | How to fix it |
|---|---|---|
| The page loads | A page that errors can't be read or quoted. | Fix the error or redirect to the working page. |
| Search engines may index it | AI Overviews and AI Mode use indexed pages. | Remove noindex; point the canonical at this page. |
| Crawlers can reach it | Blocked crawlers keep you out of the answers they feed. | Allow Googlebot, Bingbot, OAI-SearchBot, Claude-SearchBot and PerplexityBot. |
| The text is in the HTML | Some crawlers don't run JavaScript. | Serve the main content in the page's HTML. |
| A clear page title | The title says what the page is about. | About 50 to 60 characters, topic first. |
| A meta description | It shapes the snippet people read. | One or two sentences on what the page answers. |
| One main heading | One H1 makes the topic unambiguous. | Keep one H1; make the others H2s. |
| A short opening paragraph | Answers near the top are easiest to lift. | Answer the main question in the first one or two sentences. |
| Question headings | A question with an answer under it is quotable. | Use the questions buyers ask as H2s or H3s. |
| Structured data | Markup states facts reliably. | Add valid JSON-LD that matches the page. |
| Business identity | It connects your site with your profiles. | Organization markup with sameAs links. |
| Dates and authorship | Dated, attributed pages are easier to trust. | Show who wrote or checked the page, and when. |
Answer engines quote sentences that answer a question on their own. Compare two openings for the same fictional accountant:
| Before | After |
|---|---|
| “Excellence in accounting. We are a passionate, award-winning team dedicated to outstanding results.” | “Fernhill Accounting prepares fixed-fee year-end accounts for limited companies in Bristol, filed within 10 working days of receiving your records.” |
The second names the service, the customer, the place and a promise the business can show it keeps. A reader, or an AI answer, can repeat it without guessing.
An answer engine replies with an answer rather than a list of links: Google's AI Overviews and AI Mode, ChatGPT search, Perplexity, Microsoft Copilot and voice assistants. Answer engine optimization (AEO) is the work of making your pages easy for them to find, trust and quote. We explain how we deliver it on answer engine optimization, and how it relates to SEO and GEO in SEO, GEO and AEO.
A ready page is the start. Whether an assistant names you also depends on the other pages that answer the same question and on what directories, review sites and lists say about you. Track a fixed set of buyer questions each month, as in how to track your brand in AI search, or have us run the AI Visibility Audit, which tests 30 buyer questions across ChatGPT, Google AI Overviews and AI Mode, Perplexity and Copilot. Generative engine optimization is the ongoing work of earning those mentions. For Google's own rules, read how to rank in Google AI Overviews.
The short answers
An AEO (answer engine optimization) checker reviews a page for the basics that let answer engines use it: can their crawlers reach it, can it be indexed, is the text in the HTML, and does it answer questions clearly near the top. This one runs 12 checks on one page and explains each result, with the fix where one is needed.
No, and be wary of any tool that gives you a single AI visibility score. AI answers change with the wording, the platform, the location and the day.
To see whether assistants mention you, ask the same buyer questions each month and log the answers, or use our AI Visibility Audit. Search Console's generative AI report shows how often your pages appear in AI Overviews and AI Mode.
A direct answer in the first sentence or two, headings that match the questions people ask, specific facts such as who you serve, where, and how pricing works, and evidence such as examples, dates and named authors. Google says no special markup or AI files are needed for its AI features; clear, useful pages are what count.

Questions
No. The checks cover what you control on the page. Whether an assistant cites you also depends on the question, the other pages that answer it and what other sites say about you.
Some crawlers read a page's HTML without running its JavaScript. Text that only appears after scripts run may be missed, so the answers that matter should be in the page as the server sends it.
No. It notes whether the site has one, but doesn't count it, because Google says special AI files aren't needed and no AI platform requires one.
A search tool that replies with an answer instead of a list of links, such as Google's AI Overviews and AI Mode, ChatGPT search, Perplexity and Microsoft Copilot.
Your main service, location and pricing pages, then the guides that answer the questions buyers ask before they choose a provider.
There are no rankings to track, but you can see impressions: Search Console's Generative AI performance report shows how often links to your site appeared in AI Overviews and AI Mode, by page. To see whether you're named, ask the same buyer questions every month and log the answers, as our guide to tracking your brand in AI search explains.
There's no standard one. Each tool defines its own, usually from how often a brand is named or cited across a sample of AI answers. This checker doesn't score visibility; it checks whether a page is ready to be quoted.
Only the page you enter and its site's robots.txt and llms.txt, from public websites, with a short timeout. We keep results for up to an hour to avoid fetching the same page repeatedly, and nothing else is stored.
