It's been 2 months I started this site. Purchased a diversity link building package from BHW a month ago to diversify anchor text as much as possible before building PBN links. I've been tracking the rankings from almost 2 months and they were never stable. Sometimes they jump 15 places up and the very next day they drop down lower than initial rankings, when this happens I open WMT to check if there's any penalty message. But no, there's nothing. Can someone let me know what's the reason for this unstable rankings? and what can I do to make them stable?
