Content and affiliate offers need to be designed for mobile devices, with plain text, bold visuals, and a clear call to action. It is imperative to use responsive site design so that your content will look good on any screen size.
You can also use social media to promote your affiliate offers as people spend more time on social media apps than other services. Carefully study good examples of posts, links, and ads that will appeal to your audience and use them as the basis for picking your offers to promote.
