In a very competetive niche im starting to see new sites (1-2 months old) rise to the top beating well established sites. Its always the same, they have like 10-15 pages of crappy content and mostly the text makes no sense but keywords are there.
Checking the backlink profile on these sites its full of russian and india backlinks. Sometimes like 10-20k links.
These sites seems to stay 1-3 months in the top before Google figure it out. Problem is that there are tons of these, just convering the top and its all automated.
It seems like Google taken a step backwards because blackhat spam site has never been this easy. Maybe its because they removed age trust and reduced backlink power for established sites? I have no idea but im very suprised to see how easy it is to game now.
