Shopify has three different account types as well as standalone third-party products like themes and apps. Commissions are paid for sales of any of these products, including users who sign up for a 14-day free trial and then convert to a paid account. Shopify also has a wide range of blog posts, webinars, and video tutorials that can be linked to with the standard commission paid on any sales that are generated.
Focus on reviewing products that fall within your niche. Then, leveraging the rapport you have created with your audience and your stance as an expert, tell your readers why they would benefit from purchasing the product you are promoting. It is especially effective to compare this product to others in the same category. Most importantly, make sure you are generating detailed, articulate content to improve conversions.
