Google Sending Notifications Of Unnatural Links Pointing To Your Site
Essentially Google has been sending out emails to certain webmasters informing them that they were in violation of the guidelines not because they were linking to anyone but because of INCOMING links like buying links or link schemes (which just about covers all black hat links).
the real interesting part to me is this part of the letter Google sent out
"We encourage you to make changes to your site so that it meets our quality guidelines. Once you've made these changes, please submit your site for reconsideration in Google's search results.
If you find unnatural links to your site that you are unable to control or remove, please provide the details in your reconsideration request."
Normally that kind of language is reserved for a site that has been penalized.
worse using that letter I was able to find webmasters who WERE penalized for link spam/ buying links
Penalty due to apparent sabotage--Please help - Webmaster Central Help
My websites rankings have completely vanished from Google. Please help! - Webmaster Central Help
Further research indicates they mostly likely were not deindexed but their rankings did suffer a penalty.
So what is Google up to now? Has anyone got one of those emails?
Anyway be careful out there.
