One of my sites lost it's page rank overnight from 3 to 0. I don't know if it's connected to your changes or not and what kind of impact it's going to have on my business.
For now I can't seem to find the reason for it, as we didn't do nearly NOTHING on this site. Paradoxically the shop on the same domain has page rank 1 (dropped from 2).
I don't understand it and it's a bit annoying as we're doing this for nearly 3 years and were steadily growing without any link farms and crap like that. now it seems like someone is punishing us? I can see the sites that are using all black hat techniques you can imagine, changing the web into a dupmster going up without no problem.
Should I start spinning articles, contribute to cluttering the net by useless content and link from blog syndications and link farms to be appreciated by a mighty google?
