How It Works

From broken link
to bottom-line impact

Most tools just tell you something is broken. 404Alert tells you what it's costing you.

01
We crawl your entire site
404Alert scans every page, every link — internal and external. Nothing slips through, nothing hidden.
02
We estimate the revenue impact
Using traffic benchmarks and conversion data, we turn each broken link into a dollar figure you can act on.
03
We alert you instantly
The second a new broken link appears, you get notified via email, Slack, or SMS — before customers notice.
