Because 2Checkout exclusively sells software and digital products, it is best suited for established influencers whose target audience is interested in buying products in this niche. But while you won’t find any physical products for sale, 2Checkout is probably the market leader in selling software of every type, including very specific use case items (like software that can convert Microsoft Word documents to PDF, for instance).
Review sites feature reviews of products/services that the marketer has tried and can attest for. Each product/service review includes a link or banner ad that will take customers to the merchant partner's website. The advantage of review sites is that they require less frequent updates. Marketers simply have to make minor tweaks to their websites to ensure that search engines continue to list the website in their search results.
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.
