DO NOT send out loads of emails to people you don't know or who haven't requested an email from you.  This is called SPAM.  SPAM is bad and merchants do not accept this and could ban you from promoting their products in the future.

6. Create Individual Selling Pages - it is most effective when trying to sell one product/service per page than trying to save time and effort by placing 20 different products/services on one page.  Take the time to concentrate on one merchant per page (along with a couple of related links).

Simply sticking a banner on a website is the easiest method, but it's not the most effective.  The ideas above will take a bit more time but it will be time well spent.
