DevDome Link Monitor is two tools in one. A passive 404 monitor logs every missing-page hit as it happens and keeps human hits apart from crawler noise. An on-demand link scanner checks every link in your published content in small background slices, and only calls a link broken after it fails twice in checks separated in time. Free, with no link limit.

Site owners have two complaints about link checkers: links wrongly called broken, and scans that hammer the server. Link Monitor is built to avoid both.
A link is only marked broken after two failures in checks separated in time. Timeouts, DNS and TLS errors are shown as Unverified with the reason, and 401, 403, 429 and anti-bot answers as Could not verify, never as broken.
Every 404 is logged as it happens with the normalized path, hit counts, last referrer and first and last seen. Hits are split into human and bot from the user agent, so crawler noise never buries the paths real people hit.
Each 404 path is fuzzy-matched against your published slugs. With DevDome Redirect Manager active you get a one-click Create redirect prefill; otherwise a copy-ready .htaccess rule.
Re-check a link, edit the URL in every post that contains it, unlink it while keeping the anchor text, or dismiss it. Every change needs WordPress edit rights on each affected post and lands in an audit trail.
Scans run in small resumable slices you can pause or cancel, driven by your open browser or WP-Cron, with at most two links per host per tick and low default budgets.
No IP addresses stored, no cookie set, and referrer query strings never kept. Scan results stay in your own database; the optional email summary from DevDome carries counts only.
The 404 monitor starts working the moment the plugin is active. The link scanner runs when you tell it to.
Install Link Monitor from WordPress.org. The 404 monitor starts logging missing-page hits immediately, with no setup.
Open DevDome, then Link Monitor, and click Scan Links. The scan works through every published post, page and product in small slices while the screen is open or via WP-Cron. Pause or cancel at any time.
Work the Broken Links list: re-check, edit, unlink or dismiss. In the 404 Monitor, turn the paths real people hit into redirects with the one-click suggestion.
Because it refuses to guess. A link is only marked broken after failing twice in checks separated in time; timeouts, DNS failures and TLS errors are shown as Unverified rather than broken; and 401, 403, 429 and 999 responses are shown as Could not verify. What is left is much more likely to be genuinely broken.
404 logging adds one indexed lookup and one write, and only on requests that are already 404s. The scan runs in small chunks with low default budgets and at most two links per host per tick. It does run on your server, so lower the batch sizes in Settings on small hosts.
It matches the user-agent string against known crawler patterns. User agents can be forged, so treat human as not obviously a crawler. Requests with no user agent at all are counted as bots.
Yes. From the review table you can edit a URL (updated in every post that contains it), unlink it while keeping the anchor text, re-check it, or dismiss it. You need WordPress permission to edit every post the link appears in, and every change is recorded in an audit trail.
Yes on both. Every feature is free with no link or site limit. A free DevDome account is only needed for the optional email summary of newly broken links. On multisite, settings, the 404 log and scan results are kept per site.
Install Link Monitor free from WordPress.org and see which links are really broken, and which 404s real people hit.
