Why people switch from Broken Link Checker by AIOSEO

• The AIOSEO checker leans on AIOSEO’s ecosystem and cloud service, so people wanting a self-contained scanner move to Broken Link Checker.
• Its free tier caps how many links it monitors, so sites with large link counts move to Broken Link Checker or external services like Dead Link Checker.
• People who prefer an off-site crawl that adds no load to WordPress move to Dead Link Checker or WP Broken Link Status Checker.
• Those wanting simple scheduled email reports move to Link Checker Pro.

Broken Link Checker – Overall replacement

Broken Link Checker, now maintained by WPMU DEV, is the original WordPress link scanner and checks internal links, external links, and images, flagging problems you can edit or unlink in place. Against Broken Link Checker by AIOSEO, it works as a self-contained tool without tying you to a wider SEO suite. Its drawback is that the deepest, fastest cloud scanning and higher link limits sit behind the Pro plan.

Choose Broken Link Checker if you want the established, self-contained scanner with in-dashboard fixing.

Link Checker Pro – Scheduled reporting

Link Checker Pro scans your site on a schedule and emails reports of broken links and other link issues. Against Broken Link Checker by AIOSEO, it centers on reporting and monitoring rather than being part of an SEO plugin. Its weakness is a smaller user base and thinner documentation, so you get less community support if something goes wrong.

Choose Link Checker Pro if you want scheduled scans and email reports over in-page editing.

wp-broken-link-status-checker – Simple manual scans

WP Broken Link Status Checker is a lightweight plugin that checks the HTTP status of your links and lists any that return errors. Against Broken Link Checker by AIOSEO, it stays minimal and avoids background processes that can tax shared hosting. The trade-off is limited features: there is no automatic monitoring or in-line editing, so you review and fix results manually.

Choose wp-broken-link-status-checker if you want an occasional, no-frills status check without background scanning.

dead-link-checker – Off-site crawling

Dead Link Checker is primarily an online service that crawls your site from its own servers and reports broken links, with a companion plugin to tie in. Against Broken Link Checker by AIOSEO, its crawl runs off-site, so it adds no ongoing load to your WordPress install. The drawback is that fixes are not done in WordPress; it finds links but you edit them yourself.

Choose dead-link-checker if you want an external crawler that puts no scanning load on your server.

It is well maintained, integrates cleanly with the AIOSEO dashboard, and handles routine link monitoring without the resource strain older scanners were known for.
