FAQ
How are conflicts between Allow and Disallow directives resolved?
Modern search engines follow the most specific match principle, prioritizing the directive with the longest matching character path length.
How do wildcards (* and $) operate in robots.txt syntax?
* matches any sequence of characters, while $ anchors the rule to the URL ending (e.g. Disallow: /*.pdf$ blocks all PDF files).
Does testing send live HTTP requests to my live website?
No. The path matching logic simulates Googlebot RFC rules completely client-side in your browser without contacting remote hosts.
