It’s always fun when you find another cool use for your own service!

Today, I started using tracking images on my 404 pages to count how many page not found requests the site was getting.

These tracking images tell me which requests are getting 404/page not found responses and where they’re coming from without having to dig through my referrer logs!

This way, I know whether I’m serving too many 404 pages, and what I need to do to fix them.
