Fixes, biggest first
Let GPTBot crawl the site
Your robots.txt blocks OpenAI's crawler, so ChatGPT learns about you only from other sites.
Let ClaudeBot crawl the site
Your robots.txt blocks Anthropic's crawler, so Claude learns about you only from other sites.
Let PerplexityBot crawl the site
Your robots.txt blocks Perplexity's crawler, so it can't cite your pages in answers.
Add real copy to the page
Readable text is a tiny share of the page's code, or there's very little of it. Crawlers summarise words, not markup.
Offer a machine-readable interface
A valid /openapi.json or /llms-full.txt lets AI agents use your product or read your docs in full, not just your homepage.
Mirror llms.txt at /.well-known/llms.txt
Some tools look in the .well-known folder instead. A copy of the same file covers both.
