I had a site in a very Comp Niche, and the keyword research was done very carefully, without much effort i was ranking #2 for my main keyword and was getting many searches for my internal keywords. I purchased original good quality articles Was slow on link building, just used 100 articles per day AMR and 1-2 linkpushes per week to internal pages and today the site got deindexed ... Webmasters Tools say that site wasnt following G's policies.. WTF!! Ive submitted a reconsideation request ... My crappy autoblogs are flourishing like anything and a genuine information rich site got deindexed... Google You are FULL OF BUGS!!
