I get so many followers with this pop-up that I wrote about here. Bloggers who want the same results sign up using my affiliate link and I get $20 per sign up AND I also get paid if someone clicks on the pop-up and makes a purchase even if they never read my article. I explain more in detail here but it is by far the EASIEST affiliate program to make money.
If you’re in the WordPress industry like I am (whether it be design, development, or SEO) I have accumulated quite the list of WordPress affiliate programs. I excluded those I found unsuccessful or pay too little to make a profit from, specifically ThemeForest, Creative Market, and low quality theme stores like Template Monster. Hosting pays well and I wrote a tutorial for SiteGround’s affiliate program and StudioPress themes which are my 2 highest paying affiliates. Those tutorials have tons of screenshots/social proof especially for SiteGround.
