How Broken Links Hurt Your SEO & Reputation

Broken links don't fix themselves. And the damage adds up fast.

Broken Links Hurt Your SEO

Search engines penalize websites with 404 errors and broken links. Every broken link is a dead end for Googlebot and a missed ranking opportunity for you.

Visitors Leave, Never to Return

A broken page frustrates visitors instantly. Most won't bother reporting it. They'll just leave and choose a competitor instead.

Your Reputation Is at Stake

A website full of errors looks abandoned and unprofessional. First impressions matter, especially when you're trying to win new customers.

Fix Issues Before Anyone Notices

With automated monitoring, you catch broken links early. Before Google crawls them, before visitors hit them.

Automated 404 Monitoring - No Manual Work Required

Add your website once. That's it

Stay Ahead of Google

Google Search Console tells you about errors it already found. Too late. We regularly scan your website and alert you before Google or your visitors ever notice.

Free When Others Charge

Most broken link checkers lock automated scans behind a monthly fee. dislike404.com gives you full automated monitoring, email alerts and adjustable scan intervals - completely free.

You're in Control

Add your website once and let our crawler do the rest. Choose your notification style: no emails, errors only, or a full status update after every scan.

Built with Respect for Your Server

Adjustable crawl speed, robots.txt compliance and a clearly identified bot. Good tools don't hammer your server.

Start Monitoring Your Website for Free

Both plans are completely free. Verify your website to unlock higher limits, faster scans and more features.
