AI Visibility Check: Can ChatGPT Cite Your Site?

A free ten-second check of whether ChatGPT, Perplexity, Copilot, Claude and Gemini can read, understand and cite your site: crawler access, llms.txt, schema, quotable content, dates.

In plain words

Type in your website address and in ten seconds you see whether ChatGPT, Perplexity and Google's AI answers can read your site and quote it when someone asks a question you answer. You get a score out of 100 and the three things to fix first, in plain words. Nothing to install, no account.

What you get

How it works

  1. Enter a site. Any public address. The checker reads the homepage, robots.txt, llms.txt, the sitemap and up to three pages.
  2. Read the score. Five areas, weighted by what answer engines need first: access, a map, an entity, something to quote, dates.
  3. Fix the top three. Most sites move twenty points with robots.txt, llms.txt and an answer-first paragraph on the pages that matter.

What it is not for

Why I share this

I sell property to international buyers. It is a niche where a single advertising lead costs more than most products on this page, and where the buyer reads for weeks before writing to anyone. For years the enquiries came from paid ads. Then I built content sites that answer the questions those buyers ask, and the enquiries started arriving on their own: from Google first, then, more and more, from ChatGPT and Perplexity, which quote the pages when someone asks.

The numbers are on the cases page: organic clicks up 279 percent month over month across thirteen brands in more than ten countries, and a brand-new site that reached its first organic traction within six weeks of going live. Every tool on this page is a piece of the pipeline behind those sites, stripped of my data and packaged so you can run it in your own niche: the method for finding what a market actually searches for, the page shapes that get quoted, and the checks that stop a bad page from going live.

I am not a software company. I am an operator who got tired of paying for every lead, and these are the tools I use every week. If they work for you the way they work for me, tell me; if they do not, the refund is seven days and no questions.

Frequently asked questions

Is it really free?
Yes. It is the automatic first two pages of the paid audit, offered so you can see whether you need the rest.
Why does it sample only three pages?
To answer in ten seconds. The sixteen gates read every page of your own repository; this check reads what a stranger can fetch.
What is a good score?
Eighty and above: engines can read and quote the site. Under forty-five: they mostly cannot. Between the two, the three fixes listed usually close the gap in a day.
