Seeing a change in the SERPs over the past 18 hours...somewhat distinct from long tail change we've seen over the past week. Our rankings for all of the short tail terms I track jumped back to levels I haven't seen since Sept. 09. Results have the same cast of characters as always until about spot #15, at which point the results become deep pages on authority sites, as opposed to the home page of lesser sites (which dominated up to page 3 or 4 before the change 18 hours ago).
Not sure what it all means.
I'm searching google.com from the US (East Coast).
