How is popularity determined?

Blogs on WeblogMatrix are usually sorted by popularity. Of course it's nearly impossible to determine how popular a Blog really is.

For WeblogMatrix we use an indirect measurement. The more popular a Blog is, the more people will write about it on the Internet. And with writing come links…

We use the URL-Metrics API by to query the approximate number of unique domains linking back to the Blog's home page.

This is not an exact science, but it should be good enough to get a rough idea on how Blogs compare in popularity.
