Mucked around with the Yahoo API a little bit, and I must admit it’s pretty nice. I wish the Google API was as fast and had as much features.

My first useful thing I did with it was I added to the keyword tracker so it can track historical search engine rankings for Yahoo (I also added MSN while I was at it).

Turned out pretty cool… now you can see ranking changes for all three search engines over time on a single chart. Weeeeeee…. :)
