Anyone know if google is able to tell the same 4 sites are often linked from the same sites? I found a source of very legitamate authority links, and im lazy and cheap so I link my 4 clients from every single site. So far it seems to be working, kind of. As long as I build links all rankings skyrocket. Is this a good idea or will google slap me for this? What do you do on your PBN? Note, im not using a PBN.
