See whether Google and AI crawlers can read, trust and cite your site. Ten seconds, no account, and every result shows what was measured and how.

- Nothing changed on your site
Follows the documentation ofRFC 9309OpenAIAnthropicPerplexityGoogle
How it works
Three steps. About ten seconds.
Enter your address
Type your domain. No account, no card.
We read it like a crawler
We fetch robots.txt, llms.txt, your home page and your server settings once, without running JavaScript.
You get a verdict and the evidence
The first things to fix, then every check, each with what we saw and how we measured it.
What it checks
Four areas, measured directly.
| Area | What is checked | How |
|---|---|---|
| AI access | Whether 13 AI and search crawlers may read the site | robots.txt evaluated with the Robots Exclusion Protocol (RFC 9309), crawler by crawler |
| Content | Text in the raw HTML, opening paragraph, headings, title, description, H1, structured data | The HTML the server sends before any JavaScript runs |
| Technical | robots.txt, sitemap, canonical, mobile viewport, www redirect, missing-page behaviour, response time | Direct requests to your server, with redirects inspected, not followed blindly |
| Trust | HTTPS redirect, certificate expiry, HSTS | A real TLS connection and the response headers |
Honest limits
What this audit does not tell you.
A free snapshot cannot answer everything. Here is what is outside it, and where it is measured instead.
Live AI answers
Whether ChatGPT, Perplexity or Gemini mention or cite you. That needs real questions asked over time, and runs in the app.
Rankings and traffic
Where you appear on Google. Only Google Search Console holds that data.
JavaScript rendering
This scan reads the raw HTML. It flags pages that look empty without JavaScript but does not run it.
Speed and backlinks
Core Web Vitals and link profiles are separate measurements we do not guess at.
Sources
Checked against the people who write the rules.
Where a vendor documents how its crawler behaves, this tool follows that documentation. These are the pages we rely on, so you can verify any claim yourself.
- RFC 9309: Robots Exclusion Protocol ↗The rules we apply: most specific group, longest matching rule, Allow wins a tie.
- OpenAI: crawlers and user agents ↗Purpose of OAI-SearchBot, GPTBot and ChatGPT-User, and how robots.txt applies to each.
- Anthropic: how its crawlers work ↗ClaudeBot, Claude-User and Claude-SearchBot, and how they honour robots.txt.
- Perplexity: PerplexityBot and Perplexity-User ↗What each fetcher is for and why Perplexity-User generally ignores robots.txt.
- Google: common crawlers ↗Googlebot and the Google-Extended token, and what Google-Extended does not affect.
- Google: structured data introduction ↗Which structured data Google can use and the guidelines for it.

Questions
Straight answers.
Why is there no single score?
One number hides the thing that matters. A site can have a perfect title and still block every AI search crawler. You get a plain verdict and a count of checks passed, so the number is never bigger than the evidence behind it.
Is it really free?
Yes. No account, no card. Scans are limited per visitor each hour so the service stays available to everyone.
Does it change anything on my site?
No. It only reads public pages, once, with the AIRankSurgeBot user agent.
What do you keep?
The result for an address is kept for up to 24 hours so a repeat scan is instant. Nothing is tied to a person, because there is no account.
Can you promise AI citations if I fix everything?
No, and nobody honestly can. Fixing these checks removes the common reasons a site cannot be read or cited. It does not guarantee a mention.
