There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
Don’t set a goal to write 3 blog posts a day… set a goal to write 1 blog post a week and make that post super helpful, long, and filled with information that is so valuable you will say “yeah, people will link to that.” 90% of my traffic/affiliate income comes from just 20 tutorials, many of which are 5+ years old. But I am constantly updating them to make the content better.
