There are several ways you could monetize your article.
* Write copy that is well trafficked and receive a steady stream of ad revenue.
* Write copy that has less traffic but is optimized for a high paying key search term, generating good ad income as well.
* Use the article to promote the sale of an item and receive a commission for the sales, such as Amazon capsules.
* Use the article to promote the product or a service, and you're paid by THAT group for the sales because they are tracking your referrals.
* Use your article to promote your business or service, and it ends up advertising your own business.
