The Amazing Formula business model is based on 2 sources of income:
a. Google AdSense ads.
b. Affiliate Programs
Which is better? there is no clear answer to this question.
Some niches will produce better with affiliate programs others with AdSense,
you should test on a niche by niche bases. Usually you'll make more money with
an affiliate site, unfortunately there may be many instances where you will
find a good niche with keywords that can be easily ranked but no suitable
affiliate program, in this case you'll use AdSense ads, and by the way, this
will happen to you a lot.
Once you find a good keyword to target you start looking for
an affiliate program that will go with this site. As a rule of thumb you should
always prefer to promote digital products (eBooks, software, online services,
etc.) over physical products. Why? because digital products come with higher
margins which in most cases translate into higher commissions to the site
owner.
