Free AI visibility checker

What this checker looks at

• Crawler access: what robots.txt tells 12 crawlers, from OAI-SearchBot and Claude-SearchBot to Googlebot and Bingbot, and whether your server lets them in when they ask.
• Firewall and CDN blocking: we request your homepage under the names of the main AI crawlers and compare the answer with a normal request, which catches bot protection that robots.txt never shows.
• Content signals: whether your robots.txt tells AI systems they may use your pages in answers.
• Discovery: an XML sitemap, whether robots.txt points to it, how recently your pages changed, a canonical URL, and whether your llms.txt follows the format.
• Content: how many words are in the HTML before any JavaScript runs, one clear H1, and sections under descriptive H2s.
• Understanding: title, meta description, declared language, Organization or WebSite schema, and sameAs links that tie your brand to its profiles elsewhere.

How the score works

If crawlers can't get in at all, nothing else matters, so a failed access check caps the score at 40. 85 and above is strong, 65 to 84 is good, 45 to 64 needs work and anything lower means assistants are struggling to see you.

Assistants and the crawlers behind them

Each assistant relies on its own crawlers, so a site can be open to one and closed to another. The report shows ChatGPT, Claude, Perplexity, Gemini, Google's AI Overviews and Copilot side by side, with the crawlers each one needs.

Blocking only training crawlers is a reasonable choice, and the checker scores it as a pass. The full list, with what each company says about its own crawlers, is in which AI crawlers to allow in robots.txt.

Blocked at the firewall without knowing it

robots.txt is only half the story. Bot protection, web application firewalls and CDN settings can turn AI crawlers away before robots.txt is ever read. Cloudflare has asked new domains whether to block AI crawlers since July 2025, and from 15 September 2026 its default for new domains blocks training and agent bots on pages that show ads.

So we ask for your homepage a second time under the names of OAI-SearchBot, Claude-SearchBot, PerplexityBot, GPTBot and ClaudeBot. If a normal request gets your page and those get a 403 or a challenge, something on your server is refusing them. Some firewalls only refuse a crawler's name when it comes from an address the crawler doesn't use, so check your logs before changing anything.

Why JavaScript-rendered sites often go unseen

Google renders JavaScript, but many AI crawlers fetch the raw HTML and move on. If your content only appears after scripts run, those crawlers see an almost empty page. The word count check shows you what they get.

Readiness checkers and citation trackers

Two kinds of tool call themselves AI visibility checkers. This one checks readiness: whether assistants can reach and understand your site. Others ask ChatGPT or Gemini a handful of questions and report whether your brand came up. Both are useful, but they answer different questions.

A single answer from ChatGPT is too random to mean much. Measuring real citations takes the same prompts asked repeatedly over time, which is what AutomatedSEO's citation tracking does. See how to measure citations across assistants.

How to improve your AI visibility

• Let the search and fetch crawlers in, in robots.txt and at your firewall. The report gives you the rules to paste.
• Render your main content on the server, so it's in the HTML every crawler receives.
• Open each key page with a direct answer, then break it into sections under H2s that name the question each one answers. See how to structure a page an assistant will quote.
• Describe your business the same way everywhere, and add Organization schema with sameAs links to your profiles.
• Publish and update regularly. Assistants favour current sources, and a site that last changed a year ago gives them little to cite.
• Add an llms.txt. It's optional and cheap: our llms.txt generator drafts one from your sitemap.
• Earn mentions on the sites assistants read: reviews, directories, industry press and communities.
