Google has been aggressively going after companies that it believes are violating its SEO guidelines in recent months, particularly link networks. This is first penalty that we know of against what Google considers a “guest blog network.” Google on Friday announced taking action on the following: German link network efamous; another German agency network; and Spanish and Italian link networks.
Authors and especially blog owners are wondering if the penalty extends further to their own sites, blog posts and links acquired via “My Blog Guest”. We don’t know for sure!.
Google’s action comes less than a week after Cutts warned penalties were imminent. It isn’t yet clear which link networks, or how many, were penalized.
Announcements of penalties to link networks have become a near weekly occurrence of late, impacting sites in many languages.
