------------------------------------- You can get started with $20-$50 Mini Media Buys promoting almost anything you want.
SEO, Viral, Content Marketing and Social Media are great methods, but they are notoriously slow and are rapidly changing making it hard to both keep up and even gain traction.
Paid traffic is the fastest way to scale and profit to $100/day or higher.
While Adwords has extremely strict rules about how and what you can promote, Facebook Ads are getting stricter, and require you to constantly change ads, and interact with and moderate the audience. Good solo ad sellers are hard to come across, rarely allow affiliate offers, and it requires writing numerous emails, landing pages, funnels while also having to check clicks were delivered.
Online Media Buying however is the most accessible and cheapest. It doesn't get the same buzz as other platforms and so competition is low, and rules on what and how you can advertise are significantly more relaxed - making it the easiest, fastest, and cheapest form of paid online advertising.
You can literally get traffic in some wide-appeal niches for $0.004 per visitor! Obviously smaller, more specialist niches cost more, but you can still typically find the cheapest clicks in the industry.
