What it does

Redirect manager — 301, 302, 307 and 308 redirects, 410 gone and 451 unavailable for legal reasons; regular-expression patterns with $1 captures, groups, notes, hit counts, a tester that follows every hop, bulk actions and spreadsheet import and export.
Automatic redirects — A changed slug, parent or category writes a redirect from the old address (a page with children moves them all with one rule); a deleted post or product sends visitors to its parent or category, or answers 410; publishing it again removes the redirect.
Chain and loop fixer — New redirects never create a chain: older rules are pointed at the new address. A check finds chains, loops and missing targets and fixes them in one click.
Import redirects from other plugins — Redirection, Yoast SEO Premium, Rank Math, All in One SEO, SEOPress and Safe Redirect Manager, even after they are deactivated, plus spreadsheets and .htaccess rules; a dry run first.
404 monitor that cannot fill your database — Each missing address is one counter: how often, first and last seen, the page that linked to it; robots kept apart, scanners ignored, at most 10,000 addresses kept; redirect any of them in one click, with a suggested page, and a weekly e-mail.
Safe permalink and domain changes — Before a new permalink structure, category base or domain, see every address that will move; the redirects are written first, then the switch is made. Old domain names keep reaching the right page.
Site search insights — What visitors search for on your own site and which searches find nothing, turned into new pages in one click. One counter per phrase; who searched is never kept.
