In order to prevent from getting negative panda points from google, is a unique content linkwheel enough for rank #1 low competition long tail keywords?
The linkwheel I am going to use is modified in that there are two tiers; my site is linked to four other tier-one sites. Each tier-one site is linked to four tier-two sites which are also connected to each other, forming a four circle subwheel. One tier-two is connected to my site directly.
a: My site -> four tier-one web 2.0's
1: tier-one web 2.0 -> four tier-two web 2.0's
1a: one tier-two web 2.0 -> my site
