Shareasale is an affiliate marketing service provider that acts as a platform for advertisers and publishers to come together in a mutually beneficial partnership. Advertisers signup on Shareasale to promote their products and services through affiliate links. On the other hand, publishers or affiliates signup on Shareasale to find products that align with their interests and can promote through their platforms. Shareasale works by providing tracking links and banners that the affiliates put up on their blog, social media, or any other online platform. When a visitor clicks on the link and makes a purchase, the affiliate earns a commission from the sale.
