Trace every redirect hop, not only the final page
Browsers hide most redirects because they automatically navigate to the destination. Toolmera records the starting URL, status code and Location header at each hop, then shows the final response separately.
That makes it easier to identify chains such as HTTP → www → non-www → new path, or an old campaign URL that still passes through multiple legacy destinations before reaching the current page.
301 vs 302 vs 307 vs 308 redirects
301 and 308 are commonly used for permanent redirects, while 302 and 307 are commonly used for temporary routing. The methods differ in historical and method-preservation behavior, so the correct choice depends on the application rather than SEO shorthand alone.
For migrations, the most important practical checks are that the intended old URL redirects to the correct new URL, the chain is short and the final destination returns a successful response.
Why long redirect chains can complicate SEO and performance
Every extra hop adds another request before users and crawlers reach the final page. Chains can also hide configuration mistakes, create inconsistent canonical paths and make large migrations harder to audit.
Use this checker after domain changes, URL restructuring, HTTPS migrations, trailing-slash changes and campaign cleanup. Then update internal links so they point directly to the final canonical URL where practical.
