Finally, in some cases, you may work with a company or individual directly as an affiliate; rather than going through a network. Entrepreneurs or companies may run their own affiliate program and you can apply directly to them to promote their products and services. If you see a product that you would really like to promote as an affiliate and the company doesn't offer a formal affiliate program, you can always reach out to them to work out a private deal as well.
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
Vendors engage the services of affiliates to do marketing of the product on their behalf. But how do vendors and affiliates meet? Well, vendors can engage affiliates directly to sell their products and services. Another option is for vendors to join affiliate networks. These are companies whose sole purpose is to serve as the meeting place for vendors and affiliates. The advantage of an affiliate network is that a vendor can find thousands of relevant affiliates there without having to run around looking for them all over the internet.
