Is Google rolling out another Update ?
There has been quite a bit of talk just recently about another major update happening, it’s yet to be confirmed, however there is a theory that it all relates back to a big linking network being penalised.
Over in Russia there is a link network (SAPE) which is so widely used, some claim up to 80% of sites over there have links directly from it. Google are said to have clamped down on it in rather a grand style, penalising every site involved.
So how does this affect me?
lets say (for the sake of simplicity) that you have 10 links coming in to your website from various places, none from the SAPE network. However a couple of your stronger links are pointing in from sites which get their link juice either directly from the network itself, or from yet another layer of websites which do. Ultimately you have absolutely no control over this, you could have begged, or earned these links in good faith, but now they are worthless impacting your own sites positions as you have just lost a fifth of your links. But worse, they could be your strongest links.
If this network is as large as I’m led to believe, and I must add I’d never heard of it before, then the effects could be rippling through the web for weeks, as sites are de-indexed, then the sites they link to start to drop, then the sites they link to and so on, round and round until all that link juice is gone!
