True internet marketers know that you have to understand Search Engine Optimization (SEO) in order to really make money online. SEO, however, is a convoluted, hairy beast that will eat you alive without a second thought. There are basically two major "schools" of SEO: White Hat and Black Hat.
With each of these schools, their methods for optimizing search positions varies greatly, and the way that they generate traffic also varies greatly. But the major concern I want to focus on is the actual difference between the hat colors.
White hats really aren't fashionable for hardly anything nowadays. If you wear a white top hat, you're really more suited for Vaudeville plays than for making money online. White baseball hats are okay, but they can get dirty very easily, and can turn from white hats to dingy brown hats in a flash. It's just easier to keep a darker-colored hat looking good over a longer period of time than a white hat.
Black hats would be my preference, because again, they're more maintenance-free. Plus, if you accidentally spill something on it (this is harder to do when you're actually wearing it), you'll be able to cover it up better.
The only drawback to doing SEO the Black Hat way is if you wore a black top hat, like Dudley Moore did in that 80's movie "Arthur"; this would be WAY out of style. But again, due to the stain-covering factor, Black Hat may ultimately be the way to go.
In summary, try both hats every now and then...it will largely depend on your outfit. Doing this will detonate a cataclysmic concussion blast of online profit generation that will melt your skull with bone-crushing cash flow!!!
