What this AI visibility checker tests

One scan runs three audits against the live page — the same signals search engines and AI assistants use to decide who gets shown.

AI Visibility (AEO)

Whether AI assistants can reach, read and cite your page.

  • ✓AI crawler access: GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, CCBot
  • ✓JSON-LD structured data and business identity schema
  • ✓FAQ, Article and Product schema that AI answers quote from
  • ✓Question-and-answer content and heading structure
  • ✓llms.txt, and whether content is readable without JavaScript

SEO Health

The fundamentals that decide whether Google can index and rank you.

  • ✓Indexability, noindex directives and Googlebot access
  • ✓Title tags, meta descriptions and canonical URLs
  • ✓H1 and heading structure, content depth, image alt text
  • ✓Mobile viewport, HTTPS, sitemap and language declaration
  • ✓Rich results eligibility, Open Graph and Twitter cards

Page Speed

How fast the page responds for visitors and crawlers alike.

  • ✓Time to first byte and server response
  • ✓Brotli or Gzip text compression and caching headers
  • ✓HTML weight, script and stylesheet counts
  • ✓Render-blocking scripts in the document head
  • ✓Image lazy-loading, WebP/AVIF formats and set dimensions

How it works

  1. 1

    Enter any page URL

    No signup, no password, no access to your site. We read only what any crawler can: your HTML, robots.txt, sitemap and llms.txt.

  2. 2

    We scan the live page

    Around 60 seconds for three scores, then we crawl the rest of your site through your sitemaps for a whole-site average.

  3. 3

    Fix what matters first

    Every issue links to a step-by-step guide with the exact code or setting to change, ranked by the points it recovers.

Frequently asked questions

What is AI visibility, and how is it different from SEO?

▾

SEO decides whether your page appears in a list of blue links. AI visibility — also called Answer Engine Optimization or AEO — decides whether an AI assistant like ChatGPT, Gemini, Claude or Perplexity can reach your page, understand it, and name your business in its answer. A site can rank well on Google and still be invisible to AI, most commonly because its robots.txt blocks AI crawlers or its content only renders with JavaScript.

How do I check if ChatGPT can see my website?

▾

ChatGPT reaches websites through crawlers named GPTBot, OAI-SearchBot and ChatGPT-User. If your robots.txt file disallows those user agents, ChatGPT can never read or cite your site. Enter your URL in this tool and the AI Visibility report shows each AI crawler's access individually, along with the exact robots.txt rules blocking them.

Why is my site blocked from AI crawlers when my robots.txt allows them?

▾

A CDN can override your file. Cloudflare's AI Crawl Control feature injects its own managed block into robots.txt, disallowing GPTBot, ClaudeBot, Google-Extended and others before your own rules are read. Check Cloudflare's dashboard under AI Crawl Control and set AI crawlers to Allow. Some hosting firewalls and security plugins block these bots by IP as well.

What is llms.txt and do I need one?

▾

llms.txt is an emerging plain-text file at the root of your site that gives AI models a curated summary of your business, services and key pages, in the same spirit as robots.txt for crawlers. It is not yet an official standard and no engine guarantees it will read one, but it costs nothing to add, very few sites have one, and it lets you state plainly who you are rather than leaving models to infer it.

Is this tool free, and does it need my password or website access?

▾

The scan is free and requires no signup, no password and no access to your site. It reads only what is publicly available: your page HTML, robots.txt, sitemap and llms.txt — the same files any search engine or AI crawler fetches. You provide an email only to unlock the full dashboard.

Does this show my Google ranking position?

▾

No, and any free tool claiming to is guessing. Real ranking positions come from Google Search Console for your own site, or a paid rank-tracking API. What this tool measures is topic match: how clearly a page signals that it is about a given query, scored from where the words appear across your title, H1, headings, copy, URL and schema. A page scoring zero is not in the running at all; seventy or higher is properly set up to compete.

How can I improve my AI visibility score quickly?

▾

In order of impact: unblock AI crawlers in robots.txt and at your CDN; add JSON-LD structured data identifying your business; add an FAQ section answering the exact questions customers ask, marked up with FAQPage schema; make sure your content is present in the raw HTML rather than rendered by JavaScript; and publish an llms.txt file. The tool's report ranks these by the points each one would recover on your specific site.

How many pages of my website does the scan cover?

▾

It scans the page you enter first, then finds every other page it can through your sitemaps and internal links and scores those too, up to 150 pages. Progress is shown live and you can stop at any point and keep the results gathered so far. Each page gets its own AI, SEO and speed score, and the dashboard shows the average across the whole site.
