22. Advertising – This is definitely the most old-school way of earning money with a blog. It’s also starting to become the least common way. You can sell advertising spots directly on your site or you can sign up with a company like Google AdSense or Media.net. Either way, you won’t see a whole lot of money from ads until your views are well into the thousands each day.
When there are multiple affiliates involved in one transaction, payment gets much more complicated. Sometimes it’s even possible for affiliates to jump in at the last minute and claim commissions for customers brought in by other affiliates. Successful programs use multi-channel attribution to ensure the affiliates that create the most value get paid the most.
