What is stopping a Google employee from signing up for BMR or other blog networks and using them for a few months and then identifying all of (or many) of their blogs for deindexing?
Maybe that's what they've been doing...
I can only assume they have better things to spend their time on or want people to think they don't know exactly what's up with blog networks.
I DO use blog networks, sometimes as a decent portion of my link building, but I simply cannot understand people who base their link building entirely around it and then get confused when their rankings drop significantly. It's because you are grossly gaming the system and you got caught. That's it, fair is fair right?
