Tried to search but didn't find anything of value. As soon as you've got a few niche sites it gets difficult to keep track of them. When you have 50 it gets more difficult and when you pass 100 it's almost impossible if you don't keep track of your niche sites. I'm currently using a simple excel document to keep track of domain, PR, latest backlink, latest post, income last month, etc. This is starting to get out of hand because of to many niche sites and I'm therefore asking you for advice. How do you monitor your niche sites?
