Understanding Robots.txt
Key Functions:
- Allow/block specific crawlers (Googlebot, Bingbot etc.)
- Prevent crawling of private/admin sections
- Optimize crawl budget allocation
- Specify sitemap locations
How Search Engines Interpret Robots.txt
- Not a security tool - Files blocked can still be indexed if linked
- Crawler-dependent - Some bots ignore directives
- Case-sensitive - /admin/ ≠ /Admin/
How Crawlers Process It:
- First file accessed when visiting a site
- Parsed line-by-line for directives
- Rules applied to subsequent crawling
