Are You a New York Times Best Seller?

Black hat marketing is where marketers will do something against the terms of service to gain an advantage over others. The trick is, just like you heard, figure out the algorithm for getting on the list, and then figure out a way to cheat the algorithm. Black hat marketing leaves you at risk of being banned on the very place you're trying to be popular. You don't always know if you're doing a black hat marketing strategy or a white hat marketing strategy.
