Hi, I know about Black hat is : Black hat optimization often employ "Tricks" such as hiding white text on white background, spamming keyword tags with hundreds of keywords, or cloaking, these black hat methods may appear to be a good thing, and in the past did fool the Search engine's. Is there any more info i can have thanks for replying...
Buying links from link farms, are also a black hat method of SEO. Doorway pages are also a BH method.
BH method has a lot of Search Engines Tricks... http://seoblackhat.com is pure Bh discussions. But The Real BH Tactics is really Tough to Find out.
Effectively doorway pages could also be called landing pages. The only difference is that doorway pages are worthless crap while landing pages are streamlined to suffice on their own. Common for both is that they are highly optimized for organic search traffic. So instead of making your doorway pages just a place to get skipped optimize them as landing pages and make the users convert right there.
Black Hat is thinking up new ways to do SEO... it's totally all trickery, and thinking of ways to leverage white hat methods exponentially. is it good? not really. is it bad? not really. is it fair compared to white hat? definetely not.
