Affiliate Marketing can be a great way to build wealth and capitalize on the traffic you are pushing to your site from PPC and SEO efforts. Basically you are letting Google put ads on your site via AdSense, and every time someone clicks on one of those ads, you get a commission. It isn’t much, can be pennies at a time, or sometimes dollars at a time (depending on the cost of click you’re sending to Google). But bottom line – as long as it costs you less to acquire those clicks than the commission you’re receiving, it will make you money.
