Redirect Loop

A redirect loop (also called circular redirect) is a configuration error where a URL redirects to another URL that ultimately redirects back to the original URL, creating an infinite loop. Browsers typically detect these loops and display a "Too many redirects" error, and Googlebot abandons crawling URLs involved in redirect loops.

Redirect loops are identified using Screaming Frog SEO Spider, which detects circular redirect patterns during crawl, and via browser developer tools showing the network request chain. Google Search Console's Coverage report flags redirect errors, and fixing them requires carefully reviewing and correcting .htaccess, CMS redirect rules, or server configurations.
