Since July 2014 I read for the first time about affiliate marketing, I never heard of this way of working before. Until then, I have worked in MLM (multi-level-marketing). Which wasn't that suitable for me. MLM is a very aggressive way of marketing, and you do need to harass everyone around you to join. That's not quite me. Affiliate marketing works very different. You write reviews about products of a company, and when people decide to buy something after reading your review, you get a few percentage of the sale. That's more my line of work.
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans).
