Arsen Rabinovich: PBNs are not sustainable, the amount of money and time it takes to build a good, undetectable network surpasses the amount of time and effort in doing quality outreach.
Patty Mantaloons: If you blow your nose against the walls of your house, I suppose you could consider it painted green. Better off with a real can of paint and a brush. #pretentiousanswer #buticouldnthelpmyself
Roger Montti: I recently published what is probably the only description of what the Penguin algorithm actually might be that is backed up with links to research and patents.
Every point I make in that article is backed up by authoritative links so that you can read it, learn it, and know that it`s not just opinion pulled out of thin air but based on solid fact.
Some others have taken a stab at working out what Penguin is but their articles are only GUESSES because their articles do not cite scientific research or patents. Many of those other articles are basically JUST opinion.
The article I published has citations to research and patents to back up every point I make. While I can`t say definitively that the article cracks the black box of what Penguin is, it`s the quite likely the most authoritative article on Penguin you are going to find. I know that`s an audacious statement but read it first then judge it against any other article on Penguin. You`ll see why I stand behind that article so firmly.
I encourage you read it and then make your own decision about PBNs.

Are PBN`s worth it?
