How to Get Indexed by AI.
Make your website visible to AI crawlers.
AI indexing is fundamentally different from Google indexing. Each major AI platform has its own crawler — GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended (Gemini) — and each has different capabilities, preferences, and limitations. Getting indexed by all of them requires understanding how each one works and ensuring your site serves them usable content.
The AI crawler landscape
ClaudeBot (Anthropic)
Benefits from clean HTML, structured data, precise definitions, and pages that explain tradeoffs and comparisons clearly.
PerplexityBot
Often fetches pages for citation-backed answers. Direct answers, source-friendly formatting, and fast responses improve its ability to cite you.
Google-Extended (Gemini)
Part of Google's AI ecosystem. Strong entity clarity, structured data, and conventional Google crawlability all help.
How to ensure AI indexing
Configure robots.txt correctly
Explicitly allow all AI crawlers. Many default robots.txt configurations block AI bots. Add allow rules for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended.
Serve complete HTML
Many AI crawlers do not run a full browser render. Your priority content should be available in the initial HTML response through server-side rendering, static generation, or public AI-readable pages.
Create an XML sitemap
AI crawlers use sitemaps for URL discovery. Ensure your sitemap covers all important pages and is referenced in robots.txt.
Use Appear for crawler visibility
Appear helps identify AI crawler visits, verify what they receive, publish AI-readable public content, and keep routing checks aligned with robots.txt, sitemaps, schema, and canonical URLs.
