Evergreen content is content that continues to gain search traffic and readers long after it has been published.I want to point out a few features of evergreen content that are often overlooked, but still necessary to a successful content marketing strategy.

 Remember again that evergreen isn’t just for readers — it’s for search engines, too. There are specific types of content that are particularly capable of pulling in search traffic year after year. At the same time, this is the very type of content that readers will willingly devour.

Case studies seem pretty un-evergreen, but they’re actually awesome.The term “case study” is an excellent search modifier for long-tail queries that get tons of traffic. Many of the best content producers in the business are publishing “case studies.” The content in these studies is often offered in PDF or report-style form.Other researchers cite these studies and link to them, making them a powerful conduit for traffic and link building.
