FallbackRedirect keeps old URLs working after you rename pages, move a site, or delete content. It stores redirect rules, serves 301 / 302 / 307 responses on the front end, and logs unique 404s so you can turn the worst broken links into redirects.
Under Settings FallbackRedirect you get six tabs:
- Overview — open 404s, redirect hits, a 14-day chart, and the top broken links
- Redirects — add, edit, disable, or delete rules (exact, prefix, wildcard, or regex)
- 404s — grouped broken links with hit counts, last referrer, one-click repair, ignore, and CSV export
- Migration — CSV import/export and automatic 301s when a published permalink changes
- Settings — engine, monitor, privacy, retention, and uninstall cleanup
- About — plugin info and version
How SEO protection works:
- Front-end matching runs on
template_redirectbefore the theme 404 template - Exact rules are looked up by hash; prefix, wildcard, and regex rules are checked next
- Changing a published post or page permalink can auto-create a 301 from the old path
- Looping rules (same source and destination on this site) are rejected
- Admin, login, and cron paths cannot be used as sources
- 404s ignore bots, logged-in users, static file extensions,
.phpprobes, and wp-includes / plugin / theme scans by default - IP addresses are stored as a salted hash, not in the clear
