Traditionally, users have had a hard time re-engaging with sites on the web. Push notifications enable you to build experiences that users can engage with “outside of the tab”–they don’t need to have the browser open, or even be actively using your web app, in order to engage with your experience. Best of all, these notifications appear just like other app notifications. Currently we’re seeing over 350 million push notifications sent every day in Chrome, and it’s growing quickly. Beyond the Rack has found that users arriving to their site by push notifications browse 72% longer than average users and spend 26% more.
