How to write titles and descriptions for short-form clips
The text around a clip does two jobs: pull the viewer in, and tell the platform what the clip is about. The balance between those two differs by platform.
On TikTok and Reels, the caption is mostly a second hook — a line that adds intrigue or context to the video, plus three to five specific hashtags. Keep it short; long captions get truncated and rarely help.
On YouTube Shorts, the title is effectively a search field. A clear, keyword-forward title ('How to price a freelance project') does discovery work that a clever title doesn't, because Shorts surfaces in search and suggested feeds tied to long-form.
Across all three, put the most important words first, don't bait-and-switch (a title the clip doesn't deliver on tanks retention and trust), and match the language your audience actually searches.
OptimaClip's per-platform export step is where this metadata lives, so the TikTok caption and the Shorts title for the same moment can be written for their different jobs instead of copy-pasted.
Titles and on-screen text
The on-screen text in the first second does more work than the post title, because viewers decide before they read anything else. Make it state the tension or benefit in a few words: "The pricing mistake that cost us $40k" beats "Episode 52 highlights".
For YouTube Shorts, the title also helps search. Put the main phrase people would search near the start ("How to clip a Twitch stream in 2 minutes").
Descriptions and captions by platform
TikTok: a short caption with the topic in plain words helps TikTok search; add a question to invite comments. Instagram Reels: a first line that hooks, then context; keywords in the caption help Instagram search. YouTube Shorts: a descriptive title, a short description and a link to the full video. LinkedIn: the first two lines show before "see more", so lead with the insight.
Templates you can reuse
"How to [result] without [pain]". "[Number] mistakes [audience] make with [topic]". "I tried [thing] for [time]. Here's what happened." "Why [common belief] is wrong". Keep a list of the titles that performed best and reuse their structure.
