The trigger

Site has no robots.txt or empty robots.txt

The fix

Create /robots.txt at the root. At minimum, allow all + reference your sitemap. Without it, AI crawlers and search engines have no explicit policy to follow.

Code example

# /robots.txt
User-agent: *
Allow: /

Sitemap: https://yoursite.com/sitemap.xml

# If you want to allow AI crawlers explicitly (recommended for visibility in AI engines):
User-agent: GPTBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /
