Build My Rank is a private blog network, not unlike Linkvana, where serious internet marketers can promote their sites. The network consists of high quality, aged domains only (PR1-PR7). The entire network is hosted on multiple Class A, B, & C IPs to protect your links. Each individual Build My Rank post must be at least 150 words in length and totally unique. Build My Rank does not accept any spun content. By using unique content snippets or posts they ensure that you’re building risk-free natural looking links through their service
As added value the system does automated social bookmarking of all your links to ensure you get some additional link-juice and to meet their claim that 95%+ of all posts will be indexed month to month. This is a useful addition as non-indexed links are pretty much useless to you.
