User-agent: *
Allow: /

How It Works

User-agent: Specifies which bot the rules apply to. Use * for all bots.

Allow/Disallow: Controls which paths the bot can or cannot crawl. Paths support wildcards (*).

Crawl-delay: Requests bots to wait X seconds between requests (not all bots honor this).

Sitemap: Tells search engines where to find your XML sitemap.

Common Patterns

Disallow: /Block entire site
Disallow: /admin/Block /admin/ directory
Disallow: /*.pdf$Block all PDF files
Allow: /public/Allow /public/ directory
