YouTube Shorts title best practices for clips cut from long videos

What YouTube actually says about Shorts titles

Most advice on how to title YouTube Shorts is guesswork dressed as rules. The official pages are short, so it is easy to list what they do say. The first is the limit: YouTube Help says video titles have a limit of 100 characters and cannot include invalid characters. The Data API documentation adds that a title may contain any valid UTF-8 character except < and >.

We could not find a YouTube page that says how many characters of a title are shown before it is cut off on a phone, so this page gives no such number. Write the part that matters first and treat everything after the first few words as a bonus.

Does the title matter, and do descriptions?

We found no YouTube page that says title wording ranks a Short. What it does say is that its recommendation system learns from whether viewers choose to watch and how much they watch, and that relative watch time is broadly more important for short videos. In plain terms, the title's real job is to be an honest reason to press play for the right viewer.

The description is the same story. YouTube documents the size and the hashtag behaviour, and warns that excessive tags or repetitive sentences are against its policies. It gives no guarantee that keywords in the description change reach. Use it for what a viewer would want next: context, the guest's name, and a link to the full episode.

How to write a title for a clip from a long video

1. Start from the clip, not the episode. The title describes this 30 to 60 seconds, not the show.
2. Lead with the promise in plain words. Say what the viewer will hear or learn in the first four to six words.
3. Name the person or topic if the viewer would search for it, but only if it is true of the clip.
4. Check the clip pays it off in the first sentence. If the title says 'the mistake that cost me my company' and the story starts at 40 seconds, change the title or the clip.
5. Leave out brackets, all caps and emoji strings unless they carry meaning. They use up characters and add little.
6. Put the full-episode pointer in the description, not the title. A line such as 'Full episode: ' followed by the link, on its own line, is easy to find.

Hashtags are a separate decision; hashtags in title or description covers where they go and what YouTube says about them.

YouTube Shorts title ideas by clip type

The examples below are written for this guide, not taken from real videos. Swap in the real detail from your clip.

If you want opening lines rather than titles, the TikTok hook ideas guide uses the same podcast examples and works as well for Shorts.

Where KeyMo fits

KeyMo's job is the clip. It takes a long video, up to three hours, finds moments, and returns up to 15 vertical 9:16 clips, each with a score out of 10 and a one-line reason that can double as a note when you write the title. Only clips scoring 7 or higher are kept, so a weak episode returns fewer. Captions are word by word, and exports have no watermark on any plan.

Plans start at $12 a month for 300 source minutes; there is no free plan. See pricing. The podcast to Shorts page walks through the rest of the process.
