If you want to profit from the goodwill of your regular visitors, you need to let them know that when they click on those ads and buy something, you'll get a percentage of sales, the earnings of which work toward the maintenance of the site (or a new car for you, or whatever). That way, the next time they intend on making a purchase at the merchant's website, they might remember that going there through your ads allows them to support your site.
