Please note that our Legacy Themes have been replaced by new Thrive Theme Builder Themes. While our Legacy Themes are still functional, we are no longer actively developing them. This article explains why the Thrive Theme Builder themes don't need fixed "Featured Image" sizes.
Performag is our first magazine theme, ideally suited for sites that are monetized by display advertising. It is also designed specifically to increase user engagement on the site so that you can get more page views and more ad impressions.
