I have noticed a plunge in traffic to my site starting around the 3rd week in March. I thought maybe it was due to Google local coming online, but now I see that my AltaVista and All the Web link pop plummeted at exactly the same time. My link pop in each of those was around 180 and now its around 35. Is this due to Yahoo snapping them up? Does anyone have any insight into why this might have happened? Thanks!
