What is an AI visibility checker?
An AI visibility checker tests whether your website is technically ready to be read, understood and cited by AI answer engines like ChatGPT, Perplexity, Google AI Overviews and Claude.
Traditional SEO tools grade you for Google's blue links. This tool grades you for the layer above them: the AI-generated answer. It inspects the exact signals large language models rely on to decide whether they can parse your pages, understand who you are, and quote you as a trusted source. If those signals are missing, you can rank on Google and still be invisible the moment a buyer asks an AI instead. This checker groups its findings into three areas, AI access, content and technical, and turns every gap into a prioritized fix.
Why AI visibility matters now
Buyer behaviour has already shifted. More people ask ChatGPT or Perplexity for a recommendation before they ever open Google, and Google itself now answers many queries with an AI Overview above the classic results. When the model builds that answer, it reads a handful of sources it trusts and names a few brands. If it cannot read your site, or never learned what you do, you are simply left out of the shortlist, with no line in your analytics to tell you it happened.
That is the quiet leak this tool surfaces. It does not promise magic. It shows you, concretely, whether the machines can even see you yet, and what to fix first.
What this AI visibility tool checks
The checker runs eleven deterministic checks against your page and your domain, grouped into three categories. Each one maps to something AI systems actually use.
Are you accidentally blocking ChatGPT?
This is the check that surprises almost everyone. Over the last two years, many sites quietly added lines to their robots.txt that block AI crawlers, sometimes copied from a template, sometimes added by a security plugin, sometimes on purpose during the early backlash against AI training. The result is the same: if GPTBot or ClaudeBot is disallowed, those systems cannot fetch your pages, so they fall back on whatever they already learned about you, or on your competitors.
The checker vs. the AI Visibility Audit
This free tool answers one question: is your site technically ready for AI. It runs in seconds and hands you the fixes for free. But technically ready is not the same as actually cited.
That is what the free AI Visibility Audit adds. Instead of a bot, a person runs the real prompts your buyers type into ChatGPT, Claude, Perplexity and Google's AI, checks whether you are named or a competitor wins the answer, looks at which sources the models trust, and sends you a short personal teardown of the gaps. It is free, done by hand, and it is how most conversations with us start. Request it right inside the tool above.
