So Yahoo had a weather report on the 14th so I decided to carefully look at yahoo results in DP keyword tracker. I saw quite a bit of fluctuation up and (mostly) down. So I decided to manually check some keywords at www.yahoo.com and it seems Y! has quite a different result then the DP keyword tracker for Y!. I can only assume the Y! API is using different datacenters or something as the results are drastically different. Shawn - You seeing this?
