Hi, I am a newbie in IM. I have read some articles. So, I want to start doing IM with clickbank. I have purchased a domain & hosting and would like to make it a review site. I want to promote my site. My questions are: i) should I build backlink using GSA directly or using: review site <- tier 1 (PBN) <- tier 2 (GSA) <- tier 3? ii) should I build backlink without using GSA or other blackhat method, just post comments on forum, blog, etc with my site link? iii) I see someone is selling article rewrite service. I want to know which is better: hire someone to write/rewrite article or using spin software to produce unique content; iv) Which format of review site is better? Different game (Let's take game niche as an example) product review (game product A review, game product B review,game product C review...) VS different product review (game product review, movie product review, health product review...). v) Make comment and site link on web 2.0 will greatly increase site rank? What is web 2.0? Tumblr, Pinerest is web 2.0? Please correct me if I am wrong; Please forgive my poor english and thanks in advance for your help!
