Blogger? But you have to build a decent amount of followers. You can get free stuff to advertise, and get a cut of the sale if a follower clicks on a link to the product page and makes a purchase (called referral links). Additionally, if companies place ads on your website, you may get a financial incentive.
Many bloggers earn 6 figures for just blogging. I've heard it's hard work as they need to look good, have enticing photos, and essentially sell their brand/website.
