Questions about the AI Visibility Check
What is AI visibility?
How easily AI answer engines such as ChatGPT, Perplexity, and Google AI Overviews can reach, read, and cite a website. It depends on crawler access, structured data that names who is behind the site, and content that is readable without running JavaScript.
Is the check free?
Yes. The check is completely free, needs no signup and stores nothing. Enter a URL and get a scored report with a concrete fix for every issue it finds.
What does the check test?
Four areas: AI crawler access (robots.txt, noindex, llms.txt, sitemap), structured data (JSON-LD, Organization or Person, WebSite, sameAs), content and extractability (title, description, one H1, headings, canonical, Open Graph, server-rendered text), and agent readiness (landmarks, real links and buttons, labelled form fields, alt text).
How is this different from an SEO audit?
A classic SEO audit optimises for the ten blue links. This check focuses on what AI answer engines need: crawler access for GPTBot and similar bots, schema.org entity data, quotable server-rendered content, and markup that AI browser agents can operate.
Does a high score mean ChatGPT will mention my company?
No. The score covers the technical side: whether AI systems can access and understand the page. Whether they cite you also depends on what other sites say about you and how well your content answers the question asked. The check does not ask a model what it knows about your brand.
Why does server-rendered text matter?
Most AI crawlers fetch the HTML and do not run JavaScript. Text that only appears after scripts run is invisible to them, however good it is.
