Today I talked to a friend of mine and asked him , Did you learn any new information about seo in the last 6 months ? he said no. Google is up to something they aim paid links , they aim paid blog posts and they are doing it their way. for defending have you learned anything new in the last 6 months ?
Of course we are learning everyday but I am talking about information that helps a lot that you never known. Think about the time you did not know the importance of backlinks and learned about them I am talking about information that has importance like that.
I definetly learn new stuff everyday, you should always be fine tuning your strategies thats what SEO really is. FINE TUNING+HARD WORK=SUCCESS
Imo we did not learn it , google dictated it to us.Otherwise paid links are good cause people pay for them to you.
