Why editing server files is the risky way, and how to manage redirects safely from your dashboard.

Move rules, hit counts, and settings in one click — and verify the whole migration actually worked.
Read the guide ›Finding and fixing redirect loops
What ERR_TOO_MANY_REDIRECTS really means, and how to stop loops before they take your site down.
Read the guide ›Reading your Redirect Health grade
RedirectZen verifies every redirect end-to-end and grades the results A–F. A: everything verified working. B: working, but some redirects are fragile — chains or unexpected destinations. C–D: a small share of redirects is failing. F: failures are widespread and visitors are hitting dead ends right now. A grade also degrades one letter when verification data is too old to trust — a grade you can't trust shouldn't look pristine.
Fix failing rules from the dashboard's Issues card, then press Verify all now to re-check.
301 vs 302 vs 307 — which one when
301 (permanent) is right for almost everything: moved pages, deleted posts, changed permalinks. Search engines transfer the old URL's ranking to the target. 302 (temporary) tells search engines the move is short-lived and keeps the old URL indexed — use it for A/B tests or short campaigns. 307 is a stricter temporary redirect that preserves the request method — rarely needed on content sites.
When unsure, use 301. It's RedirectZen's default.
Why redirect chains hurt SEO
A chain is a redirect that points at another redirect. Each extra hop adds latency, leaks a little link equity, and adds one more thing that can silently break. RedirectZen flags chained redirects as fragile during verification — point the first rule straight at the final destination and the warning clears. See also: fixing redirect loops.
Migrating from another redirect plugin
RedirectZen detects Redirection, Quick Page/Post Redirect Plugin, WP 301 Redirects / Simple 301 Redirects, and Safe Redirect Manager, and imports each in one click from Import & Export. Your current rules are backed up first, and every imported redirect is queued for verification — minutes after migrating, you can see that every rule still works.
