Take advantage of affiliate program freebies when available. Many affiliate programs provide free printables, guides, webinars or other lead magnets designed to get potential customers in their sales funnel. As an affiliate, you can share these freebies with your audience using your affiliate link so if they eventually make a purchase, you’ll earn a commission, but if they don’t they still get value upfront.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
