The most successful internet marketers make money through their understanding of traffic generation techniques and nice selection abilities, not based on how pretty their sites look. In fact, you can have the ugliest site in the world and still make a ton of money, just because you know how to drive a lot of visitors to it.
This is what a lot of beginners fail to understand; they’ll spend months trying to decide which theme to choose for their site before they learn the first thing about making money online. Furthermore, you can make the same mistake by trying to monetize a website before it has the visitors.
