When do you want to get started? If you are just starting and have no audience then some of the programs may not accept your application to become an affiliate, while others will let you get set up in minutes. If you want to get started straight away then make sure you’re applying for programs that are less restrictive. Generally the larger, network style places will enable you to get going quickly while specific niche programs may require you to have a certain audience size or characteristics.
