The basics
What is a broken link checker?
Why a broken link checker matters
Visitors click a link expecting something useful but suddenly, when they land on an error page instead, most of them leave, and they rarely trust the page that sent them there. There's a search angle too. Google doesn't penalize a site just for having a few 404 pages, and it has said so publicly. But broken internal links create dead ends for crawlers, which can slow down how quickly your important pages get discovered.
What a broken link checker does
A broken link checker tests whether a web address loads properly and tells you whether it works. Fixing broken links is one of the cheapest technical SEO wins, and it needs no developer.
What Rext AI provides
You give the Rext AI broken link checker a URL and it tells you whether the page responded. If the destination is gone, moved without a redirect, or the server is failing, you find out right away.
How it works
How to use the Rext AI broken link checker
- 1
Copy the link you want to test
Grab it from your article, your navigation, an email campaign, or a backlink report.
- 2
Paste the full URL into the field
Include the protocol at the start, either https:// or http://. Without it, the tool can't process the address.
- 3
Click "Check link"
The tool requests the URL and reports whether it's accessible and responding as it should.
- 4
Act on the result
If the link works, you're done. If it doesn't, fix the typo, point it to the new address, replace it with a better source, or remove it.

FAQ
Is this broken link checker free?
Yes, Rext AI provides many technical SEO tools free of cost. You can use it without paying, and it works for any public URL.
Can it scan my whole website?
Rext AI's broken link tool checks one URL at a time, which suits spot checks and pre-publish reviews. For a site-wide audit, use it alongside a crawler and test individual links here whenever you need a quick answer.
Why does my link show as broken when it opens fine in my browser?
Some sites block automated requests, require a login, or restrict access by country. If a link opens for you but fails here, test it again and check whether the destination limits bots.
Do broken links hurt my Google rankings?
Not directly because Google doesn't apply a penalty for 404s. The real damage comes indirectly, through poor user experience, lost trust, and wasted crawl paths on internal links.
How often should I check links on my site?
Check every new page before it goes live and review older, high-traffic content every few months.
Start with one keyword.
Run it on your own site. Read the sources. Decide with the article in front of you, not a promise.
