Hello senior guys,
I faced some problem about ranking. I have 10 social bookmarking sites with different IP and 1 shopping site (shoes), before 10+ days ago my site rank was top6/15/20 with different keywords, I placed my shopping site link (banner image, alt tag is shoes) in all social bookmarking site before 10 days ago, right now my shopping site rank go down completely.
My site keywords is comfortable shoes, flat heels and etc.
I think social bookmarking site not perfect for my site as a backlinks. Anybody can help me???
