Important Notes
- Robots.txt is a suggestion, not a security measure
- Bad actors may ignore robots.txt directives
- File must be named exactly "robots.txt" (lowercase)
- Must be placed in the root directory of your website
- One robots.txt file per domain/subdomain
- Changes may take time to be recognized by crawlers
- Use noindex meta tags for stronger blocking
