1.4k links in 404 Monitor!!! What to do ?

Hello,

Thank you for contacting the support.

We only report 404 errors. We do not have information on how or why they are generated. You can get further insight into them by enabling the advanced monitor at WordPress Dashboard > Rank Math > General Settings > 404 Monitor:
https://rankmath.com/kb/monitor-404-errors/#advanced-404-monitor

That will give you more information like referrer and user-agent.

You can also fix these errors by redirecting them to a related page on your website: https://rankmath.com/kb/fix-404-errors/

Or, you can add them to the exclusion list at WordPress Dashboard > Rank Math > General Settings > 404 Monitor > Exclude Paths if you know that those are false positives.

If you are seeing random 404s that you know for a fact are incorrect – it is likely generated by a bot and can be safely ignored. You could also use a service like Cloudflare to block out access to bots so they do not use up your server resources.

Here’s a great article on how to secure your WordPress website:

Hope that helps.

Thank you.
