Hi, I'm in a situation difficult to understand, thanks to Google. One of my micro websites ranked #2 for a long time and until yesterday. Today when I woke up, it was gone to page 6. And not only mine, but other competitor micro sites on page 1 are all over page 6 and 7 now, like all of us get slapped. And why are we all getting slapped, I know this happens but not like every single competitor on the first page, at the same time! Is this a manual review? If it is, why didnt they just deindex the sites if they think they are not good? If it is an auto penalty, what can i do to get out of it? I haven't been backlinking the domain heavily lately, only getting very high PR links from authority web sites just to hold on to my position at #2. What are your ideas?
