I have an german Site about backlink solutions (highly targeted uniques per day ~ 100). I mainly review backlink providers there which I buy. Also I offer the following often (and it is much requested): I write a positive review about your service. In exchange you do your service onto the written article. You can use it as buffer site or as a rep site you push in the serps and I get links to this certain subpage. At the end we profit both from it. Of course you can tell me anchors for your links inside the review. You are totally free how much and which of your provided backlinks point to your review site. Get in touch today and lets profit from this.
