Hi

I've recently added analytics to some of my mainstream sites (post penguin update) and a day or two after i've seen some dramatic shifts in traffic. some sites have risen and some dropped - i also made some minor changes to the sites so i'm trying to figure out what's happened. has anyone else experienced this after adding analtyics. I know this shouldn't have an effect but google have a lot more info on your site with analytics installed and maybe this is factored into their algorythm.
