## What it checks

- **Title length:** 20–70 characters (YouTube allows 100).
- **Hook up front:** the words that earn the click within the first 40 characters.
- **Description opening:** the first 150 characters mention the title's topic.
- **Links:** what the video mentions is linked.
- **Hashtags:** at most 3; only the first 3 show above the title.
- **Chapters:** a 0:00 timestamp plus at least 2 more, each 10+ seconds apart.

- **How long should a YouTube title be?** Between 20 and 70 characters. YouTube allows 100, but search results and the home feed cut long titles, often around 60 characters on mobile. Put the words that make people click in the first 40.
- **What makes a good YouTube description?** The first 150 characters show in search and above "...more", so say what the video is about there and repeat the title's main words. Then add chapters (0:00 plus at least two more timestamps), the links you mention and up to three hashtags.
- **Is anything I type sent anywhere?** No. This checker runs in your browser; nothing you type leaves your device. Signed-in Vid0 users also get AI-rated title ideas and description drafts.
