YouTube Shorts Caption Generator (Free, Keyword-First)
A YouTube Shorts generator that writes for the two things Shorts actually rank on: title-line keyword match and viewer retention. Ten title plus caption pairs per batch, each one keyword-first and hook-first.

Why the title line is doing most of the work
YouTube Shorts sits inside YouTube's main search graph, which means the title line is a real ranking signal, not just a caption. The generator front-loads the primary keyword in every title, keeps titles under 40 characters so they do not truncate in the Shorts shelf, and uses the caption field for the secondary keyword and hook clarification.
Descriptions on Shorts should be 100 to 200 characters. Longer descriptions do not add ranking value on Shorts and pull attention away from the retention signal, which is the dominant ranking factor.
Hashtags on YouTube Shorts
Two to four topical hashtags is the sweet spot. #Shorts is auto-applied by the platform, so adding it manually is optional. The generator ships tags that match the keyword cluster in the title rather than generic reach tags.
Frequently asked questions
How long should a YouTube Shorts title be?
Under 40 characters so it does not truncate in the Shorts shelf and search results.
Do I need to add #Shorts?
Optional. YouTube auto-detects Shorts by aspect ratio and duration, so the tag is a soft signal at best.
Does the title matter more than the caption?
Yes on Shorts. The title feeds YouTube's search index, the caption reinforces the hook and adds a secondary keyword.
How many hashtags for a Short?
2 to 4 topical tags. Beyond that adds noise without adding reach.
