TOP FIVE PBN MYTHS GOING AROUND
Pushing a domain from one registrar account to another flags your sites - Why wrong? Pushes happen every day for non PBN reasons
Google looks behind whois privacy - Why wrong? Too many people use whois privacy and have their own name without getting deindexed
Google has an algo based way of deindexing sites automatically not manually - Why Wrong? If did all the crappy content networks I see still helping people rank would be dead.
Links from non relevant sites to your PBN cause deindexing automatically - Why wrong? how many times have people on this forum linked to adobe and Microsoft - IM to non im sites - and yet they are not deindexed. Some people say anchor text mismatch is how its done. Two problems with that
A) sites expire all the time that are set up by new owners who are NOT running a PBN. Pretty big companies for totally legit reasons buy domains for branding purposes. Any automatic deindexing would kill all those sites based on their previous link profile yet there they are untouched
B) most organic link profiles ( which is what you are buying domains for when you buy a domain for links) are not anchor text heavy anyway. URL anchor links abound and various others non niche phrase variations. Most of the time you see a site really anchor text laden in their link profile theres been some grey hat black hat SEO going on
Finally theres the all time favorite - non-relevant DOMAINS cause deindexing. That one won't go away despite the fact that Amazon.com has nothing to do with the river, Facebook.com is not a site about portraits and who the world knows what adobe.com is relevant to (short name for a Doberman?) .
STOP THE MADNESS. THIS IS WHAT GOOGLE WANTS.
There are only two or three proven ways PBNs get hit. They get hit on SEO hosts, get reported or they are public networks anyone can buy space on and a google employee buys and then sees the sites in the network and deindexes them.
