Check for Broken Links scans your entire WordPress site for broken links, dead links, and 404 errors — and alerts you the moment something breaks, before Google finds it first.
Your site breaks quietly while you are busy. Pages get deleted, plugins get abandoned, external sites go offline. You had no idea. Check for Broken Links finds every broken link across your posts, pages, custom post types, comments, and slider content, and shows you exactly where each one was found so you can fix it fast.
Free Version
Run manual scans anytime and get a full results table showing every broken link, its status code, and exactly which page it was found on. Filter by type, export to CSV, and stay in full control with no automatic changes to your content.
Pro Version — Set It Once, Forget It
Pro runs automatic scheduled scans daily, weekly, or monthly and emails you. No manual checking, no guessing — just a silent background monitor that alerts you when something needs your attention.

Check for Broken Links


This plugin does the job well for pages, posts and comments. However, it does not scan the entire site, as it does not include searching to dead links in Custom Post Types - so this is my only reason for my 4 stars as oppose to 5.



UPDATE: After that awesome response, which is refreshing as some others resist and give excuses, I'm updating my review to 5 stars, can't wait for the next update - you guys are awesome and deserve it...


Works well, but lacks support for CPT.


No membership, no cloud, no muss, no fuss. Just works. Thank you :)


Perfect


Simple but effective and works as it should, thank you author.


Works As It Should

Never miss a broken link again. Scan your WordPress site for broken links and 404 errors — automatically.
