My sites are dropping like flies to independent backlink networks. It all started with one very famous one and now they are springing up all over the place. Just as the hijacking issue is a major threat to the individual site owner so are these for your SERPS.
There is now one polish network where you can get 10,000 backlinks in no time at all. Everyone is jumping on the bandwagon because it is working. Why is dangerous? Well you spend years building your backlinks in a half decent fashion. All your competition needs to do is join a network display ads on their site and in no time at all they are beating you in the serps. Too easy and nothing seems to be done about these networks even though they have literally 1000's of sites in them. The more sites that join the more powerful it gets. This is a real challenge to even the balance and take these networks out.
