Creating a residual income is one of the best ways to make sure that your marketing efforts really pay off. One of the most popular ways at the moment is by selling a service or product that has a monthly recurring fee. This could be for membership site that gives new products to its members every month. There are quite a few of these around at the moment, very often linked with the public limited rights industry or PLR. These can take the form of articles that are provided every month to the members so they can use them in their web sites without having to write themselves, e-books for them to sell as their own, or even entire web sites that are very often made to take advantage of the Ad Sense boom.

The person that you sell to keeps buying every month to maintain their membership and to keep receiving the articles, e-books or web sites. This means that you keep receiving your percentage of the monthly fee even though you only had to make the actual sale once. This is a particularly efficient way of selling, as it means you can end up getting paid hundreds or even thousands of dollars as a residual income over a length of time, for just making the one affiliate sale.

Because you keep getting paid every month even if you do not find new customers, this means that you can put a great deal more effort into the initial sale as the rewards will be greater. If you're just making single sales that do not have a residual income, you only have a certain amount of time to spend on each sale to make the affiliate income worth while.

Probably the most important part of the work you do is in selecting your affiliate program well, before you start promote it. With a single sale affiliate system you're always looking for new customers and always selling, so although the product is important, especially in the context of refunds, at least you will always be finding new customers. If you are operating an affiliate system that has a residual income attached to it, then you need to make sure that the service, whether it be articles, e-books or web sites, is of high enough value that the customer is going to not only going to buy the subscription from you in the first place, but also continue to pay month after month and so in ensure that you receive your residual income.
