See your site the way AI crawlers do
We fetch your page four times — once as a normal browser, then as GPTBot, ClaudeBot, and PerplexityBot — and compare what they get. Cloaking, JavaScript-only pages, hydration mismatches, and paywall gates show up instantly. Free with a Crawl Readiness account.
Why parity matters
Google's guidelines have always required that the content you show a crawler match the content you show a human. AI systems now enforce the same rule — if ClaudeBot gets a blank page while your visitors see a rich article, Claude can't cite you. Common causes:
- Client-side rendering — the crawler receives a JS shell it can't execute
- Cloaking — different HTML served to non-human user-agents (violates search guidelines)
- Paywall gates — humans see the content, crawlers get a signup wall
- Hydration mismatches — SSR HTML differs from the client render
- Bot-specific 403s or empty responses — WAF or Cloudflare rules blocking AI UAs at the edge
How this tool works
- We fetch your page as a normal Chrome browser
- Then in parallel as GPTBot, ClaudeBot, and PerplexityBot (with their real user-agent strings)
- We measure word overlap, response size, HTTP status, title, and meta description
- We flag high/medium/low-severity issues and give an overall parity score
Note: this tool sees your public server response. Some sites gate crawlers by IP range too — we can't detect that; a rich crawler response here doesn't rule out edge-based cloaking. Google's cloaking policy applies.
