How long should a B2B SaaS hook be?
Longer than you might guess. The middle hook is 12 words, and only 25% run 8 words or fewer.
The longest hooks went least far. Past 20 words, the middle reel reached 9× its account's followers, while the shorter bands sat between 12× and 18×. Plenty of these hooks are full spoken sentences: 36% are spoken alone and 26% are spoken and shown. Say it in one breath.
Should you say the hook or show it?
Both, almost evenly. 36% of these reels say the hook out loud with no text, 35% only show it, and 26% do both.
Text alone went furthest, 20× the follower count for the middle reel, against 16× for a voice alone and 11× when the line was both said and shown. So even in a niche this chatty, the silent line travelled further.
