With blogging, you build an audience interested in your expertise surrounding a specific type of content. By creating consistent and credible content, your audience will deem you as a credible source for advice and recommendations. Therefore, you increase the chances that your audience will trust the products or services you use and promote through your affiliate links.
For example, if you’re someone who is looking to be an affiliate– also referred to as a partner or publisher – then you’re likely to want to know about what it means to join a brand’s affiliate program, best practices for promoting their products or services, how you’re compensated for doing so, etc.

Furthermore, you can always ask other affiliate marketers for a review. Ask their experience working with a specific network.
These come in the form of “Product A vs. Product B” or “Service A vs. Service B” articles. In some cases you may even have three instead of two. The key here is to focus on the very specific similarities and differences between the two. Someone looking at this type of article wants an answer. Even if it’s along the lines of both being great, but one slightly better overall while another option is slightly better for a very specific narrow type of use.
