If you know the history of the terms White Hat and Black Hat—how they started in grainy westerns where a hat was the only way to tell the silent villain and hero apart—you may understand why I really appreciate the place of these terms in SEO.
Sure, SEO is a lot like a frontier. And Google would love you to think in terms of good and evil, but what we’re talking about today is the people who sort of stand in the middle.
The middle is a little shakier ground than most, especially after the most recent changes to one of our favorite grey hat devices: PBNs.
