Yahoo loves my backlinking, Google doesn´t

I am making more links then you make on daily basis, several times and my domains are ranking for their keywords from long time... Some time they see Google dance but they are improving ranking on regular basis... I use several keywords in anchor text ( keywords rotation)...

I never use auto content and got no such content on my site... All copyscape passed content on my site so i don't have much experience with this kind of content... Although my believe is with unique content you got better chance of ranking...
