Creating blog content is a very useful and effective way of consistently building content on a site. When creating blog posts, it's a good idea to do some keyword research to figure out what it is that your audience is interested in and searching for online. Also, be sure to research competitors, forums and social media to narrow down on topics for your blog.
Next, research individual affiliate programs to compare their structure. You want to consider factors such as how much the commission is and how often the affiliate pays. Also, make sure you understand what rules, if any, a company imposes for being a part of its affiliate program. Additionally, you're likely to make more money with affiliate marketing content that is similar to your own.
