[Jack]

Sorry cannot tell URL

My website was getting rank up day by day. On Keyword "Buy youtube views" it was on 16th page. This is very competitive keywords. I was watching ranking in morning,it was on 16th page and in evening, ranking was not in top 400 - now i checked top 500- there is no ranking in that keyword

But ranking on another keywords like : buy cheap youtube views, buy youtube views cheap - i have ranking and after penguine, my ranking come on another keywords too which are buy facebook likes cheap , buy cheap facebook fans , buy real facebook fans

I dont know, why rankings goes out on keyword : buy youtube views - 1 week passed, ranking not came

Please help!
