Bloggers can earn money from product reviews in several ways. Here are some common strategies: 1. Affiliate marketing: One of the most popular ways bloggers earn money from product reviews is through affiliate marketing. In this model, bloggers earn a commission every time a reader clicks on a link in their review and makes a purchase. Bloggers can sign up for affiliate programs with companies like Amazon, ShareASale, and Commission Junction, and include affiliate links in their reviews. 2. Sponsored content: Brands may pay bloggers to write reviews of their products in exchange for a fee. This is known as sponsored content. In a sponsored review, the blogger must disclose that they were compensated for their review.
