Load the payoff word into the first three words
Viewers decide on roughly 0.6 seconds of audio and one frame. That is about three spoken words. If your hook is 'So I've been using this thing for about a month and honestly...', the decision is made before the product exists. Rewrite so the most concrete noun or number lands in words one to three: 'Three weeks. Zero breakouts.' or 'This ruined normal coffee for me.' Same script, same length, different first breath — and hook rate typically moves several points on that change alone.
