If you run a website, blog, or online store, broken links are one of the most damaging — yet completely invisible — problems you can have. A single dead link can tank your Google rankings, frustrate visitors, and waste your precious crawl budget.

In this guide, I will walk you through exactly how to check broken links* on your website using a free, browser-based *broken link checker tool — no downloads, no signups, no cost.

What Are Broken Links and Why Should You Care?

A broken link* (also called a **dead link**) is any hyperlink on your website that points to a page or resource that no longer exists. When a user or search engine bot clicks a broken link, they get a *404 Not Found error instead of the content they expected.

The SEO Damage of Dead Links

Google's crawlers have a limited "crawl budget" for your site. Every time Googlebot hits a dead link, it wastes part of that budget on a page that doesn't exist. Over time, this means:

- Lower rankings: Google interprets broken links as a sign of a neglected, low-quality website. - Lost link equity*: If other sites link to your pages (backlinks) and those pages return 404 errors, you lose all the SEO value from those *broken backlinks. - Higher bounce rates: Users who hit dead links leave immediately, sending negative engagement signals to Google.

How to Use a Free Broken Link Checker

The fastest way to find dead links is with an online broken link checker tool. Here's my recommended workflow:

Step 1: Open the Free Broken Link Checker

Head to [FreeClientToolbox's Broken Link Checker](/tool/broken-link-checker). It runs entirely in your browser — your URLs are never sent to any server.

Step 2: Enter Your Website URL

Paste the URL of the page you want to scan. The website broken link checker will automatically extract every link on that page.

Step 3: Review the Results

The dead link checker will test each link and categorize them:

- 🟢 Healthy (200): The link works perfectly. - 🔴 Broken (404)*: The page no longer exists — this is a *dead link you need to fix immediately. - 🟡 Redirect (301/302): The link works but goes through a redirect chain. Too many redirects hurt page speed. - 🔴 Timeout: The target server didn't respond. Could be a temporary issue or a permanently dead page.

Step 4: Fix the Broken Links

For each broken link found:

1. Update the URL if the page has moved to a new address. 2. Set up a 301 redirect from the old URL to the new one. 3. Remove the link entirely if the resource no longer exists anywhere.

Why Client-Side Link Checking Is Better

Most online broken link checker tools send your URLs to their servers for processing. This means:

- Your website structure is exposed to a third party. - You're limited by their server capacity and rate limits. - You might hit daily scan limits on free plans.

FreeClientToolbox's free broken link checker is different. All HTTP requests are made directly from your browser. Your data never leaves your machine, and there are no scan limits.

How Often Should You Check Broken Links?

As an SEO consultant, I recommend running a broken backlink checker scan:

- Weekly for high-traffic commercial sites. - Monthly for blogs and content sites. - After every major content update (page deletions, URL restructuring, CMS migrations).

Conclusion

Don't let dead links silently destroy your SEO. Use a free broken link checker tool regularly to find and fix 404 errors before Google penalizes your site. The 5 minutes you spend scanning today could save you months of lost rankings.
