Every time I make PBN (private) links there is a extremely heavy google dance going on. This means keywords are falling from #10 to #50-90 and staying there for more than 30 days. Seems like since the September update the google dance became heavier and longer. Now, how can I avoid that big google dance, while still building PBN links? Normally I build around 1x link per day for about two/three weeks = 14 links. Maybe two links for a week are enough? How do you guys handle this? And do you also have such a strong google dance?
