About this tool
Paste your description and type the title. The helper checks them against YouTube's limits (100-character title, 5,000-character description, 15 hashtags), previews what viewers see before 'more', and validates chapters so they actually appear on the progress bar.
How to use it
- Type your title and paste your description, including chapters and hashtags.
- Add the main keyword you want to be found for.
- Fix anything marked with a warning, and check the preview of what shows before 'more'.
Questions
How long should a YouTube title be?
Up to 100 characters are allowed, but only about the first 60 to 70 show in search and suggestions. Put the main keyword and hook first.
How do I add chapters?
List timestamps in the description starting with 0:00, with at least three chapters, each at least 10 seconds long, in ascending order.
How many hashtags should I use?
Three to five relevant ones. The first three appear above the title; more than 15 and YouTube ignores all of them.
