Competition: 134,000,000 (google.com, broad)
Search: 8200 (monthly)
I add 2-5 backlinks everyday from do follow forum (PR1-PR6) and I placed its link on my two other blog PR2. Currently, it is on the first page of SERP google.com (#6).
Here are what I need to conform:
a. Does google prefer .ORG extension domain name?
b. No ads placed on the web page except affiliate product links. Does Google love page without ads (mainly PPC ads)?
Can someone answer my questions?
