What makes a good affiliate link monitor?
Standard broken link checkers are built for one purpose: finding URLs that return 404 errors. That's useful for general site maintenance but inadequate for affiliate marketing, where the most costly failures return HTTP 200 OK.
The criteria that matter specifically for affiliate publishers:
- Silent redirect detection — Can it detect when a link redirects to a homepage or wrong page while returning 200 OK?
- JavaScript redirect chain support — Can it follow redirects that are built dynamically in JavaScript (common in affiliate tracking)?
- Automated scheduled checks — Does it run automatically on a schedule, or do you have to manually trigger scans?
- Instant alerting — Does it notify you immediately when a problem is detected, with enough context to act?
- Revenue impact data — Does it surface click volume data alongside the broken link so you can prioritise fixes?

Bottom line
If you're running a content site with affiliate income, you need a tool that was built specifically for affiliate link monitoring — not a repurposed SEO crawler or generic uptime monitor.
The distinguishing feature to look for is silent redirect detection: the ability to identify when a link returns 200 OK but sends visitors to the wrong page. This is the most common affiliate link failure mode and the one that generic tools universally miss.
