Multiple redirects in sequence (A -> B -> C). Each hop adds latency. Aim for direct redirects to the final URL.
Fix: Update all redirect sources to point directly to the final destination URL.
Page A redirects to B, and B redirects back to A, causing an infinite loop.
Fix: Check your redirect rules for circular references. Use a redirect checker tool to trace the chain.
After redirecting HTTP to HTTPS, some resources still load over HTTP.
Fix: Update all internal links and resource references to use HTTPS or protocol-relative URLs.
Query strings (e.g., ?utm_source=google) are stripped during redirect.
Fix: Ensure your redirect rules preserve query strings using QSA flag in .htaccess or equivalent.
Using temporary redirect (302) when permanent (301) is needed, losing SEO value.
Fix: Review your redirects and change 302s to 301s for permanent URL changes.
