Help with Smart Seo (black + white)

Hi, i start with seo 2 years ago, and it is working to me, but each new google change, the things are less effective.
I use bh tools for do white seo (only for automatization and use a few all days), where can i find real ways to improve my seo works?
I listen about social networks are important in actual seo, but don't have experience on it.

Thanks for help
