Free tools for search and AI visibility

Two focused tools for diagnosing how Googlebot and modern AI crawlers see your URLs. Each runs server-side, no JavaScript rendering, just the static HTML real crawlers actually parse.

See what Googlebot actually sees

Google Crawler Simulator

Fetch any URL with Googlebot's user-agent. Inspect the title, meta description, canonical, robots directives, Open Graph, Twitter cards, JSON-LD schema, headings, response headers, and raw HTML.

  • Side-by-side cloaking comparison vs. a regular browser
  • JSON-LD schema parser with @type chips
  • SPA detection (Next.js, Nuxt, Remix, SvelteKit, Vite)
  • Indexability health check with reasons
Open tool

Are GPTBot, ClaudeBot, and PerplexityBot allowed?

AI Crawler Checker

Checks robots.txt and per-page directives against ~70 search, AI, social, and scraping crawlers. Shows the exact rule and line number that blocks any bot, plus ready-to-copy snippets to opt out.

  • Covers GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, and more
  • Detects /llms.txt for AEO/GEO discoverability
  • Exact robots.txt line that triggered each block
  • Copy-paste snippet to block whole categories

Why two separate tools?

Google Crawler Simulator answers “what does Google see when it crawls this URL?” — useful when you’re debugging a specific page’s SEO or schema markup. AI Crawler Checker answers “which of the ~70 known crawlers can access this URL?” — useful when you’re thinking about AI training, AEO/GEO visibility, or accidentally blocking key bots with a wildcard rule.
