Top 10 Free Broken Link Checker Sites in 2026

A broken link occurs when the link connects to a web page that has been removed or moved. Broken links are a negative for a website, so you should work on them every month and fix all broken links. Here is the list of the Top 10 Free Broken Link Checker sites.

Broken links hurt SEO.

When Google crawls dead links, crawl budget is wasted. When users click broken links, they get a bad user experience, and it affects the website’s ranking.

I tested 10 free broken link checker sites to find which one actually catches broken links without false positives.

Here’s what I discovered: Most free tools miss links. Some flag working links as broken. Only a few are actually reliable.

I tested each tool on a 500-post WordPress site with intentionally broken links seeded throughout.

Quick Comparison: 10 Free Broken Link Checkers

Why Broken Link Checking Matters in 2026?

Three critical reasons:

1. SEO impact: Broken links waste Google crawl budget. Crawlers spend time on dead URLs instead of indexing new content.
2. User experience: Broken links frustrate users. High bounce rate. Poor conversion.
3. Authority signals: Too many broken links suggest an abandoned/neglected site. Negative ranking factor.

As per guidelines, Broken links affect how often Google crawls your site.
