The distinction that is an evergreen product, is not a new expression. It is, however, come into more frequent use lately. In Internet marketing circles, an evergreen product is basically a product that can be promoted over and over again for an indefinite period of time. If the information is not likely to change, now or in the future, then your information product can be said to be evergreen.
What do I mean by that? There are some concepts that generally do not change. For example, if I were to create a product about how to create a website, including how to upload files, how to zip a file, then that product would be considered to be evergreen.
The one of the reasons that one would take caution with whether or not their product was evergreen is if it were part of a “set it and forget it” membership site. If you were to set up a membership site, with the intention of leaving it alone and let the material do all the work for you, you would want to stay away from topics such as Facebook or MySpace.
Another reason you might want your product to be evergreen is if you intend to attract affiliates to your site. Ideally, you want your affiliates to be able to promote your products without you having to update them.
Other examples of topics that you would not use to create evergreen products might include eBay, whose rules change all the time, and Google, whose search engine optimization secrets are never divulged and most likely change all the time.
Whether or not your product could be considered “evergreen” could also depend on how specific your information is. If you use a lot of generalities about weight loss, for example, if your product was based on the concept that to lose weight you should eat less and exercise more, then that information will stand the test of time.
The problems in that case, might arise if you decide to quote “the latest research”, because surely the latest research on most topics concerning health and wellness will change considerably in a short period of time.
