IndexDoctor in one minute
Diagnose why Google and AI may not index your pages. These answers are grounded and up to date, no hype.
- What does IndexDoctor do?
- IndexDoctor runs free technical checks on a single URL to explain why Google or AI search may not be indexing it. It inspects sitemaps, robots.txt, noindex tags, canonicals, redirects, HTTP headers, Open Graph previews, AI crawler access, and GEO readiness, then returns a plain-English diagnosis.
- Do I need an account or install anything?
- No. Every tool runs in the browser against the URL you paste. There is no login, no tracking dashboard, and no software to install.
- Which AI crawlers and answer engines are supported?
- The AI Crawler Checker tests access for GPTBot and OAI-SearchBot (ChatGPT), ClaudeBot and Claude-SearchBot (Claude), PerplexityBot (Perplexity), and Google-Extended (Gemini, AI Overviews). The GEO Checker scores the page for AI search readiness against all of them.
- How is the GEO Checker different from a regular SEO audit?
- A classic SEO audit optimizes for blue links on Google. The GEO Checker scores the signals answer engines actually use: crawlability for AI bots, content extractability, answer structure, structured data, entity trust, and preview metadata for link unfurls in Slack, X, LinkedIn, and Discord.
- Is it free?
- Yes. All diagnostic tools are free to run without an account. Some advanced AI visibility and GEO reports may expose an optional premium layer in the future, but the core checks stay free.
- How do I fix the problem after a diagnosis?
- Each diagnostic report links to a focused fix guide under /fix that walks through the cause, the remedy, and how to verify the fix using the matching tool. Long-form explainers on AI crawlers and GEO live under /guides.
