Place it at the very end of your main segment, right where your on-screen prompt appears, and keep it as the last element in that section. Follow it with a short channel sting if you use one, or precede it with a soft pop for the like graphic so the sequence builds in order.
About this sound
This is a six-second digital prompt effect built around the familiar subscribe, like and notification bell cue, with clean pops and a bright ding. It feels neat, upbeat and instantly recognisable, giving a light playful nudge rather than a big dramatic hit, like a creator tapping viewers on the shoulder to engage.
