Guys, I see that more backlinking I do, more rank I loose or more deindexed pages I have lately. I use scrapebox and my comments are targeted and "semi-intelligent", not obviously spammy I span AMR articles about 50%, some time 80%. I link to internal pages mainly for small blasts, and larger blasts i link to web 2.0s, articles and bookmarks. So, seems I am more or less careful. Yet after i get to position 3-5 all efforts lead downhill. Any suggestions? Whta you do differently and not do with new G updates?
