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 Use the tool 1. 1 ### Copy the link you want to test Grab it from your article, your navigation, an email campaign, or a backlink report. 2. 2 ### Paste the full URL into the field Include the protocol at the start, either https:// or http://.

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.
