I give up. I have tried for months to figure this out. I have 3 product review websites which were ranking fine then all of a sudden one by one they got hit with a -30 penalty (according to tools.seomoves.org/penaltychecker ) No matter what I try I cant get them back to where they were ranking before ---namely on the 1st page for their respective keywords. All websites are indexed and rank for all keywords/long tail in the top 500. Nothing I seem to do brings them back and the penaly remains. Let me know if you can help, have a detailed plan and costs. Thanks!
