LinkMender
LinkMender – Broken Link Checker, 404 Monitor & Redirects
Finds broken links and images without hammering your server, logs the 404s visitors hit, and fixes both in one click: edit, unlink, redirect, or swap in an archived copy.
What it does
Broken links cost you readers, rankings and trust. Most link checkers either hammer your server and the sites you link to, or leave you with a spreadsheet and no way to fix anything. LinkMender does the scanning politely and puts the fix one click away.
Links and images in posts, pages, custom post types, custom fields, menus, widgets, term descriptions and page-builder content are collected once and checked in the background with per-host throttling.
Features
- Polite scanning. Background batches through Action Scheduler, HEAD before GET, per-host rate limits, retries before anything is called broken.
- Fix in place. Edit the URL with instant verification, unlink and keep the text, replace a broken image, swap in the closest Wayback Machine copy, or update every occurrence of a redirecting link to its destination.
- 404 monitor. Hit counts, referrers and suggested redirect targets for the URLs visitors actually request.
- Redirects. Exact and wildcard rules with hit counts and CSV import/export.
- Editor sidebar. Link problems for the post you are editing, fixable without leaving the editor.
- Page builders. Elementor, Bricks, Beaver Builder and Divi content is scanned and fixed like everything else.
