You’ve read it a thousand times.
“Broken Link Checker is the best broken link checker plugin for WordPress.”

Not any more.

Who recommends Broken Link Checker plugin? Why many WordPress blogs do. The popular plugin seems great since with over 700,000 active installations. It does schedule monitoring and testing of all internal and external links on your site. It’s sniffing out broken links. Sometimes, around the clock checking.

[dropcap]T[/dropcap]his plugin monitors links in your posts, pages, and comments – and detects links that don’t work. If it finds any broken links. Then it notifies you from your WordPress administrator dashboard – and by email. It sounds pretty cool. But, it’s a round-the-clock vigilant sentry. Hyper-vigilant. It’s looking for unreal or inconsequential exaggerated dangers.

And dang, it’s a heavy plugin. The download zip file weighs a massive 1.0 megabytes. That’s an indicator it’s a multipurpose plugin. We don’t like those kind for speed.

Broken Link Checker is often blacklisted on managed WordPress hosting. Why? It works continuously in the background round the clock. Monotonous hitting on the server with repeated database requests. This causes high server resource usage – and overload. The server then slows down and the load time of your pages slow to a crawl. On shared hosting, it slows down everyone else site, too.

Broken links create a bad user experience. Annoyance with delays and disappointment the content is missing. It’s sloppy and diminishes your site credibility. Your site feels abandoned or stale.

So Broken Link Checker is banned on hosts like Presidium, WP Engine, and GoDaddy. They immediately remove or disable the plugin without your permission. Forbidden plugin.


The goal of a broken link checker is preventing “404 Page not found” browser errors. A broken link, also known as a dead link, is a link on a web page that no longer exists anymore. Avoiding 404 redirects helps speed up your site. The browser is waiting or hunting for a connection to a non-existent web asset. There are several reasons broken links happen:

  • The external website is offline.
  • Your link is to an old deleted or moved page of a site.
  • Your visitor didn’t type the site URL right.
  • The website’s permalink structure changed.

So what’s a better solution for speed?

First, you don’t need to leave the plugin “on” all the time. Only activate it when doing testing. But most people forget and “leave the lights on.” That wastes resources. What would your Dad say?

But an even better idea is using a lightweight plugin introduced in 2020.

Link Finder

18.6k gzip download file
Load Time: 380 milliseconds

Compare the file sizes of Broken link Checker 1 megabytes to Link Finder 18.6 kilobytes. Hmm? Which one will be faster? The tiny one or the big fat one? Go ahead. Guess.

Link Finder plugin helps you speed up your website by avoiding redirects. That in theory improves your search engine ranking. SEO benefits are nothing compared to annoying visitors to death. Link Finder is an understandable and lightweight plugin. It helps you find and repair broken links throughout your website.

To not affect the speed of your website, Link Finder does not perform active monitoring. Use it as a regular manual tool to check for broken links. Or after changing permalinks or moving your website to a different domain.


Have we tried Link Finder on PagePipe’s 2,000 links? Yes. Twice. We had fixes the first time. But our second experience was a disaster. Our guess is since the link database was so clean, the plugin took off processing like a rocket. We triggered a server resource overrun on GoDaddy servers. And taken offline temporarily. Not cool.

Oops! Shutdown.

Then the site locked up. In the end, the fix to view and edit our blog again was resetting our office router cache. (That’s right – unplug it for 10 seconds). And clear the browser cache. Somehow our IP address became a suspected attacker because of the flurry of activity. Very puzzling. But we know what to do next time.
