Understanding Results

Interpreting Results

When analyzing robots.txt files:

  • A missing robots.txt file means all public content is crawlable
  • User-agent: * applies to all crawlers unless specific rules exist
  • More specific rules override general rules
  • Disallow: / blocks all access for that user agent
  • Allow: directives override Disallow: for specific paths

Best Practices

Consider these recommendations:

  • Use specific user agent names when possible
  • Keep rules organized and documented
  • Test after making changes
  • Monitor crawler behavior regularly
  • Maintain consistent formatting
