Back when FB release FB Instant, it increased my engagement with shared links significantly. Usually, on a phone browser, the thought of clicking on a link which would navigate away from the app and load a heavy full-fledged website would make me not want to click on shared links at all. But with the lightning symbol next to Instant-supported links? Click right away. In the worst case, if the content is bad, you will back where you were in a second.
