Why does redirect count matter for SEO?
Each redirect adds ~50-300ms latency and dilutes link equity in Googles eyes. Best practice: 1 redirect max (e.g., HTTP->HTTPS or www->apex), never chain multiple redirects. Every extra hop hurts Core Web Vitals.
What is the difference between 301 and 302?
301 = Permanent (Google passes 100% of link equity, caches aggressively, crawlers update the URL). 302 = Temporary (link equity is not passed reliably, crawlers keep the old URL). For permanent moves like HTTPS upgrades or domain migrations, always use 301.
How is a redirect loop detected?
The tool tracks every URL visited. If the chain revisits a URL already seen, a loop is flagged. Real-world loops often happen with misconfigured www/apex, HTTP/HTTPS, or canonical tag conflicts — they cause browsers to abort with ERR_TOO_MANY_REDIRECTS.
