LinkBuilder.com is a price comparison engine for backlinks and sponsored content. We collect offers from 50+ link marketplaces and show them side by side, so you can see every price for the same site and choose the best deal before you buy.
Publishers often list their sites on several marketplaces at once, and each platform adds its own markup. With LinkBuilder you don’t need to check them one by one: one search shows you where a placement is cheapest.
