Hi, I read the article you are referring to. In the section of the articled titled "Top Traffic Sources Within Etsy," there is no actual traffic source called "Etsy Features." Etsy Features is referring to features on Etsy's website that allow your item to be found. These include your shopfront, treasuries, activity feed, views from teams, views from favorites, etc. There is nothing actually called "Etsy Features."
There is another box on the Shop Stats page called "Top Traffic Sources." These traffic sources are what bring people to your shop from somewhere else on the Internet. For example, Google or someone typing your shop address in. "Etsy Features" refers to traffic sources WITHIN Etsy that take people from one page on Etsy to your shop.
Someone Googles "handmade crochet scarf" and sees a link to an Etsy Shop. This = traffic source Google.
Someone searches ON ETSY for "handmade crochet scarf" and sees one in the search results. Traffic source = Search = one of Etsy's "features."
Someone is looking at a treasury and sees a beautiful "handmade crochet scarf." Traffic source = Treasury = another one of Etsy's "features."
The reason the article emphasizes Etsy's features is because it is important to use titles and tags to get found on Etsy. Someone people get their traffic from outside sources such as their blog or friends and family. There is a difference between being found outside of Etsy and being found within Etsy.
