A great affiliate marketing strategy should always prioritize long term results. You want to set up something that will work for you in the future—so you don’t have to hustle every minute of the day.
Affiliate marketing deals are pervasive across the Internet. The idea behind it is that you promote other people products, often through an affiliate network, earning a commission if people actually end up buying thanks to your marketing.

For affiliate marketers, your email list can be a great source of potential affiliate sales. While you don't want to sell, sell, sell with every single email you send, there's nothing wrong with sending a promotional email for every three value emails you send. You can add your affiliate links to your email newsletters and watch the affiliate sales roll in.
Another way to find this information is to do a simple Google search. For example, one could place the following phrase into Google Search: “(product name) + affiliate program”. (Replace “product name” with the name of the product you are promoting.) There is an interesting chrome addon called Affilitizer is available which makes this process easy.
