Story stickers head-to-head: which drives completion

Story stickers head-to-head: which drives completion
n=900 stories, 30-day window, single-sticker frames isolated.
— Poll sticker: median 11% tap rate, +4 points story-completion lift
— Quiz sticker: 7% tap, +6 points completion (curiosity holds viewers)
— Slider sticker: 14% tap, +2 points completion
Sliders win engagement-per-tap; quizzes win retention through the sequence. Question stickers underperformed all three at 5%.
So what: open a story sequence with a slider to capture cheap taps, place a quiz mid-sequence to stop the swipe-away, and save polls for when you actually need a decision input.
