ChatGPT, Perplexity, Google AI: your customers ask AI their questions. If your site isn’t readable and citable, you’re invisible. Test it now.
We read your page the way an AI would: crawler access, structure, data, citation files. Instant result, no strings attached.
…
I send you the signal-by-signal detail + what to fix first. And if you want, I’ll handle it for you.
AI visibility is whether AI assistants (ChatGPT, Perplexity, Google AI Overviews, Claude) can read your site AND cite it when your customers ask them a question. The test above measures it out of 100 in 30 seconds, no signup: it analyses your page exactly like an AI crawler would.
AI visibility measures whether a generative answer engine can find, read and reuse your site content. When a customer asks ChatGPT or Perplexity "which provider for X?", the AI answers by citing a few sources; if your site is not readable to it, you simply do not exist in that answer. In 2026, this AI layer increasingly sits between your customers and you, before the first click on Google.
Run the test at the top of this page: it fetches your homepage the way an AI crawler would and checks, live, what it can extract. It looks at three things: access (do your robots.txt and HTML let AI in?), readability (is the content in the HTML, or hidden behind JavaScript?) and citation structure (structured data, AI-dedicated files like llms.txt). The result is a score out of 100 and a one-line verdict.
SEO places you in Google's blue links; GEO places you inside the AI-generated answer. The first optimises for a page ranking, the second for a citation inside a text. Both share a technical base (HTTPS, readable content, structured data), but GEO adds a layer most SEO providers still ignore: the files and formats AI prefers, like llms.txt, Markdown versions of pages, and enriched structured data.
You will run into several acronyms for the same thing: AI visibility, GEO (Generative Engine Optimization), GSO (Generative Search Optimization) and AEO (Answer Engine Optimization) all describe the same goal, being cited by AI. The jargon changes, the discipline does not. Whatever the acronym, the only question that matters is whether the AI recommends you or a competitor. This test and my service cover them all.
Three reasons come up almost every time. One: the content is rendered in JavaScript and the crawler only sees an empty shell. Two: the site has no structured data, so AI sees text but cannot tell who says what. Three: it lacks the AI-dedicated signals (llms.txt, preference headers, Markdown version), so the site is "seen but ignored". The test tells you which of these gaps applies to you.
It is never a single setting. Several technical layers stack on top of each other, from crawler access to the signals AI prefers, and they do not carry the same weight depending on your platform. The ground moves fast: what mattered six months ago has already shifted, and one detail in the wrong place is enough to stay invisible while everything else is in order. That is exactly why most companies delegate it: not because it is rocket science, but because it is moving, easy to get wrong, and every missed point is paid for in citations lost to a competitor. Run the test at the top of the page to see where you are capped, then see how we work together to get it fixed for good.

Google SEO targets a ranking in search results; AI visibility targets a citation inside an assistant answer, like ChatGPT, Perplexity or Google AI Overviews. A site that ranks well on Google can still be invisible to AI.
Yes, they are near-synonyms for the same discipline: being visible and cited by AI. GEO (Generative Engine Optimization), GSO (Generative Search Optimization) and AEO (Answer Engine Optimization) describe the same goal under different acronyms. This test and the service cover them all.
WordPress and custom-built sites reach all three layers: visible, citable, agent-ready. Shopify, Wix, Webflow and Framer allow most on-page work but block root-served files and AI agents; the lever then becomes migrating to an open CMS or a custom build.
On an open site, most of it is won fast, often within days. The test shows directly the score you can reach after fixes: the measure of the gap between where you are and where you could be. Rather than spending your evenings on it, you hand the fixes to me and get back a site AI cites.
