There are 3 types of Affiliate marketing:
UNATTACHED AFFILIATE MARKETING:
These are your basic pay-per-click affiliate marketing campaigns where you have no presence and no authority in the niche of the product you’re promoting. There’s no connection between you and the end consumer, and all you’re doing is showing an affiliate link in front of someone’s face via Google Adwords, Facebook ads or whatever, in hopes that they’ll click on your link, buy the product, and you’ll earn a commission.
RELATED AFFILIATE MARKETING:
Another form of affiliate marketing is what I like to call related affiliate marketing. This is where you have some sort of presence online, whether it’s through a blog, a podcast, videos, or whatever – and you have affiliate links to products related to your niche, but they’re for products you don’t actually use.
INVOLVED AFFILIATE MARKETING:
Involved affiliate marketing is where you’ve used a product or service, truly believe in it, and personally recommend it to your audience. Not in a banner ad or somewhere that says “recommended resources”, but within your content, as part of your life and your strategy for whatever it is you’re talking about. The product almost becomes something people “have to have”, because it’s part of the process.
