A redirect chain happens when URL A redirects to B, which redirects to C, and so on. Chains usually build up over several site migrations or URL changes.
Each hop adds a round trip for the browser and crawler.
Chains slow pages down, waste crawl budget and some crawlers stop following after a few hops. Internal links should point straight at the final URL.
VisibilityKit Crawler flags redirect chains and shows every hop, so you can update internal links to the final destination and collapse the chain into a single redirect.
Aim for one. Two is tolerable during a migration. Longer chains should be collapsed.
Point the first URL directly at the final destination and update internal links to use the final URL.
