To gain authority and high rankings in serps you need backlinks that : 1. are from websites with good reputation 2. are easy to index 3. will remain live/indexed for a long time 4. are related to your niche 5. are not spam 6. have unique content near your link ~ Remember: quality is what google always will love. ~ So, for 5 $ you'll get 15 profile bks : 1. with pr 3 to 6 (the main domain's pr; old websites with good reputation) 2. each with unique content (100~200 words) related to your niche 3. all the bks will remain live/indexed for more than 2 yrs (I have bks from 2007 still indexed) 4. have great value due to the content where the link is put, and the domain's pr and good rep 5. get indexed easily 6. are manually created. For each campaign I allow max 5 urls from same domain and up to 10 keywords, but, for great results all 15 backlinks should be made just for one url.
