It sure is, spent some time today looking through positions 500 through 1,000 for key-words where I'm familiar with the usual players. Found a few old time, usually well ranking sites, that I was very surprised to see hanging around that neighborhood.
Itís a narrow band of sites being hit with this thing, but itís wider than what you might initially think before doing some searching. Kind of surprised thereís not more posting regarding it, but some of the usually well ranking sites that have tanked are not aggressively SEOíd so maybe the owners are a bit oblivious just yet.
But, were back to the same questions; why the sudden increase in the occurrence of these penalties, and whatís causing them.
