When I woke up today morning and as usual the first thing I did was to check the no of sales I did on Clickbank. But I fainted after seeing that I had 0 sales in last 18 hours. I logged in to Serpbook and saw that all my main keywords ranking went down to page 4 or 5 from page 1. Previous method I used to rank my micro niche sites : I used to drip feed Social Signals daily to my homepage from old Facebook, twitter and G+ accounts with profile pictures on them. See that the profile is at least 80% complete and made their data to be visible for public. It always worked for me to climb to 1st page of Google in about a week for a low competitive keyword like 2000 - 5000 searches a month. Currently I did was : Just got 15 backlinks from forum signatures from niche specific forums and now I came back to 2nd page of Google for my 2 main keywords. I know I'm bit fast in analyzing, but time is money for me. I can still see SERP movements on my other keywords. For now it worked well for me. P.S : I haven't wasted my time in getting Tiered backlinks for my niche sites. I currently own 6 niche sites and from which I earn approximately 800 USD a month. I know it's not a big figure. For now I'm scaling up everything and hiring VA's to get my work done for me. Let me see how it all goes in future. Edit : Google is like a girl, no one can understand how she'll behave in future, sad but true.
