Tommy and I have spent the last 6 hours going over a portion of our current data. It takes time going through over a thousand individual campaigns with nearly 6,000 keywords being tracked, so bear with us (Tommy finally went for a well deserved rest). I know he'd like to hold comment until the dust settles over the next few days to get a clearer picture. However, our preliminary findings show that majority of clients had a +/- 2 position movement across the board (with a large number in the top 10, some experiencing massive gains). Not everyone was so lucky, we certainly see a handful of campaigns that took dips in the SERPs within the last 24 hours. However, as we also track clients that are not using any links from SAPE the results were somewhat similar.
I'm sure Tommy will have more to comment over the next few days as we finish analyzing our data and see where positions settle.
