Check For Broken Links (URL)
Just input a URL and we'll find any broken links on it.
Est run time: 15-20s.
Usefulness: Broken links can impact SEO and lead to poor user experiences. It's good to get those fixed, if only so the site doesn't breed. We already have a site proliferation issue as it is.
Caveats: Looks for href links only, not image ones. Doesn't return 300 level responses (we follow the link). 429 means we were throttled. We account for relative URLs, but any odd relative construction will lead to broken links.
Bot Blocking: Some sites - especially Cloudflare users - may block or throttle our bots. If so, the numbers will be empty or wonky.
Additional: Fixing broken external links is a great way to improve your site's user experience, and Google will reward you with better rankings!
