The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
There are more than half a billion active websites under the sun and most of the (almost 70%) of them struggle to get traffic due to the high competition and expense of the process like SEO or Digital Marketing. However, you can simple buy targeted traffic from various sources at any time you want! Every paid ad campaign is an attempt to get traffic in exchange of money.

Some people buy traffic to get sales, some buy traffic to get leads, some buy traffic for brand exposure, some buy traffic to gain authority and improve rank on several metrics and so more.
