One of our sites has had a 2 point drop in page rank at some point, roughly, in the last two months. (last time i checked it was at the start of the year)
The only changing factors i can think of, from our end, is a dupe of some of our content, a handful of articles, to one of our newer sites. And thats about it.
Our site is quite graphically heavy, and i was wondering if google has implemented any checks on site speed, i know this has been talked about for some time now?
