Private blog networks, such as Build My Rank, own the high PR sites and allow members to post short articles to their network, with their link inbedded within the body of the text. A monthly membership fee is involved ranging from $40 to $150 a month, depending on how many domains you want to backlink or which of the blog networks you subscribe to.
Because the recent Penguin update specifically targeted dubious linking practices, and Google is now actively hunting down backlinking services, which they weren’t before. Almost without exception, the links you get from these services aren’t worth having anyway. What you get varies by service. It may be a link in a “directory” or a “bookmarking site” – just a list of links, and we all know Google hates those. It may be a link in a blog post – which sounds good, but you have to look at the quality of the blog, and usually it’s full of keyword-stuffed and either spun or duplicate content.
We all know Google hates those, too. Or finally, it may be “likes” or Tweets – I don’t think Google has worked out how to identify fake likes/Tweets yet, but they must have noticed all the ads offering the service, so I’m sure it’s only a matter of time.Bottom line is – if a service is publicly offering to create backlinks, Google knows they exist and they’re out to stop them doing it. They’re not doing anything illegal so Google can’t stop them advertising – but if they can identify their network of sites, they can de-index the lot overnight. That’s what they did to BuildMyRank (which used to be one of the big players).There are a few private blog networks, which don’t advertise and which only accept quality articles.
However good luck tracking them down! Besides, they’re expensive – it would be hard to justify paying the monthly fee unless you’re a serious internet marketer.
