I need to advertise a link?

[Jake]

That's the million dollar question. Most web sites, including Answers are on guard for referral link 'spam' and will delete posts and accounts containing it, creating your own blog on a subject that earns good search ranking is the cleanest way to do affiliate promotions, higher paying product promotions can use paid advertising, whether it's even worth promoting a junky rewards program is questionable, establishing yourself as a good citizen on some forums allows you to add a footer link to your posts, some links can be made on your own facebook pages.
