Best Free & Paid backlink checkers for SEO

Broken links are one of those things you don’t notice — until they start messing with your SEO. Pages stop working, visitors hit dead ends, and slowly, rankings slip.

That’s where a broken backlink checker helps. It finds the cracks before they turn into real problems — and sometimes, it even finds opportunity.

In this guide, you’ll see:

  • What broken backlinks actually are (and why they matter).
  • Tools — both free and paid — that catch them fast.
  • How to use broken links for smart, non-spammy link building.

Let’s make your site cleaner, stronger, and maybe even get you a few backlinks along the way.

What Are Broken Backlinks?

A broken backlink is just what it sounds like — a link that’s supposed to point to your site, but ends up going nowhere. Maybe the page was deleted. Maybe the URL changed. Either way, someone’s trying to send traffic your way, and it’s hitting a wall.

It doesn’t seem like a big deal at first. But if you’ve got a bunch of these floating around the web, they start to add up. Search engines notice. Visitors get annoyed. And you miss out on traffic, trust, and the value that link was meant to give you.

That’s why using a broken link checker matters — it helps you find and fix those dead ends before they start quietly pulling your site down.

Why It’s Important to Fix Broken Backlinks

Most broken links don’t scream for attention — they just quietly sit there, doing damage in the background. You don’t see the traffic you’re missing. You don’t feel the hit to your rankings. But over time, it adds up.

Here’s why fixing them matters:

  • Lost SEO value — If a high-authority site links to a dead page, you lose the ranking power that link was supposed to give you.
  • Bad user experience — Visitors click expecting value and land on an error page. That hurts trust — and bounce rates.
  • Missed traffic — A broken link means people who wanted to visit your site can’t. That’s potential customers slipping through the cracks.

Fixing them is low-effort, high-impact — and the right tools make it way easier. Let’s dive in.

Using Broken Backlinks for Link Building

Fixing broken links is one thing — but finding them on other people’s sites? That’s where link building comes in.

Let’s say a blog links to a guide that no longer exists. You’ve got a similar guide — or even a better one. Reach out, let them know the link is broken, and suggest yours as a replacement. It’s helpful, relevant, and way more likely to get a “yes” than a cold pitch.

It’s a simple tactic, but it works — especially if you do it right.

Here’s how it helps:

  • You’re offering value first, not just asking for a link.
  • You’re targeting real, live pages that already rank.
  • You’re building links naturally, without sounding like spam.

Done well, broken backlink building is one of the least annoying — and most effective — ways to earn links.
