We've seen consistent traffic from yahoo of about 4000-5000 visitors a month from Yahoo traffic and then all of a sudden when pulling reporting for January 2013, we saw a very significant 40-50% drop from them.

We're not seeing any ranking changes in our terms on Yahoo and are curious if anyone else is seeing the drops which may indicate some incorrectly tagged bots, or something wrong from a Yahoo side.
