Almost all older blogs deindexed

In an indication of the negative tactics link sellers face, almost all blogs on domains registered before 2011 were deindexed as part of Google’s strategy to ensure that all the advertisers money is spent on Google adwords alone. Google and those deindexing were aware of the fact that it is far easier to sell advertising on a blog which is a few years old, than advertising on a newly registered domain name.
Now those whose blog network was deindexed have to waste their time and money to rebuild their blog network.
