Free AI crawlability checker: see if GPTBot can read your site
Before ChatGPT or Claude can recommend you, their bots have to reach your site at all. This checker tests GPTBot, ClaudeBot, PerplexityBot, and Google-Extended access directly — your first check is free on the 7-day trial, no credit card.

Most sites fail a GEO audit without knowing it
This tool checks whether GPTBot, ClaudeBot, PerplexityBot, and Google-Extended can access your website, and flags anything in your robots.txt blocking them — the fastest way to find out if your site is blocked from ChatGPT without reading crawler specs yourself. A site can rank perfectly well on Google and still be functionally invisible to AI models: a robots.txt rule written years ago for a different bot, a JavaScript-heavy page that never fully renders for a crawler, or a sitemap that's gone stale are all common, and none of them show up in normal analytics. The only way to know is to check directly, bot by bot.
VisibleChamp's Crawlability Check feature is the crawlability half of this audit — live requests to a site as GPTBot, ClaudeBot, PerplexityBot, and Google-Extended, to confirm each one can actually reach it. Paired with a full site coverage scan, it answers two separate questions in one pass: can AI crawlers reach a site at all, and if they can, is what they find actually structured and complete enough to be useful.
What does a GEO audit check?
Six things, in one pass.
AI Crawlability
Confirms whether GPTBot, ClaudeBot, PerplexityBot, and Google-Extended are allowed by robots.txt and actually get a working response when they try to fetch your pages.
Website Coverage
Discovers every reachable page via your sitemap and internal links, so you know exactly how much of your site AI models can actually see.
Site Structure
Maps titles, headings, and page type across your site — the way a language model would parse it, not just a raw page count.
Content Gaps
Flags content types AI models typically look for that your site doesn't have yet, like FAQ pages or clear comparison content.
Competitor Structure
Run the same audit against a competitor's site and see the page-type gap side by side, not just your own numbers in isolation.
AI Readiness
A single, prioritized view of how ready your site actually is to be crawled, understood, and cited by AI models.
Once crawlers can get in, here's what they find
The coverage half of your audit maps every page AI crawlers can actually reach, broken down by type — so you know exactly what content exists, not just that access is allowed.

How the GEO audit works
Seven steps, from raw crawl to a prioritized action list.
Crawl the website
VisibleChamp sends live requests to your site as every major AI crawler to see what actually gets through.
Discover pages
Every reachable page gets found via your sitemap and internal links, not just the ones you manually list.
Extract content
Titles, headings, and page content get pulled from every discovered page for analysis.
Analyze site structure
Pages get categorized by type — blog, product, FAQ, comparison, and more — the way a model would parse them.
Identify missing opportunities
Content types AI models typically cite that your site doesn't have yet get flagged explicitly.
Compare against competitors
Run the same scan against a competitor's site to see the gap side by side, not just your own numbers alone.
Generate actionable insights
Results come back as specific, ranked issues to address, not a wall of raw crawl data to interpret yourself.

Book a demoSix things in one pass: AI crawlability (whether bots like GPTBot, ClaudeBot, PerplexityBot, and Google-Extended are allowed in robots.txt and get a working response), website coverage, site structure, content gaps, competitor structure, and an overall AI readiness view.
They're closely related — both terms describe checking whether a site is actually optimized for AI models rather than just search engines. VisibleChamp's audit specifically covers AI crawler access and content structure, the two things that most directly determine whether generative models can use a site at all.
Look for GPTBot rules in your robots.txt, then confirm the bot actually gets a working response from your server — a firewall or CDN can block it even when robots.txt allows it. VisibleChamp's crawlability check does both automatically for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended, and tells you exactly which bots are blocked and why.
GPTBot is OpenAI's web crawler — the bot that reads websites so ChatGPT can learn about and reference them. If GPTBot can't access your site, ChatGPT has no first-hand view of your content, which makes being recommended much harder. The same logic applies to ClaudeBot (Anthropic) and PerplexityBot (Perplexity).
A failed crawlability check means a specific AI bot either can't reach your site (blocked in robots.txt, or the server didn't return a working response) or the crawl didn't confirm access — either way, that model can't reference content it can't read.
Setup takes under two minutes. The crawl itself typically finishes within a few minutes for most sites, though larger sites with many pages can take longer since every reachable page gets discovered and categorized.
Yes — you can run your first audit on the free trial with no credit card required. Every plan includes a monthly allowance of audits that scales with your tier.
Re-run it whenever you make structural changes to your site, and periodically regardless (monthly is common), since AI crawler access and behavior can change independently of anything you do.
No — a technical SEO audit and an AI search audit check overlapping but different things. SEO audits focus on search-engine crawlability and ranking factors; VisibleChamp's audit is specifically about whether AI models like ChatGPT and Claude can access and use your content when generating answers.
