How to add YouTube titles and descriptions

Klaas builds your YouTube title and description straight from your caption — there's no separate title field to fill in. Knowing how the mapping works lets you write a caption that publishes with clean metadata.

How your caption maps to YouTube

  • Title — the first 100 characters of your caption become the video's title.
  • Description — your full caption becomes the description shown below the video.

Because the opening of your caption doubles as the title, lead with a strong, self-contained first line and keep it under about 100 characters.

Write a caption that publishes well

  1. Open the composer at Create and start a new post with your video.
  2. Put the title you want as the first line — descriptive, keyword-rich, and under ~100 characters.
  3. Continue with the rest of your description below: context, links, and hashtags.
  4. That whole caption becomes the YouTube description; the opening line becomes the title.

Metadata tips

  • Opening line — this is your title, so front-load the words your audience would actually search for.
  • First ~125 characters — roughly this much of the description shows in search results, so put what matters early.
  • Keywords — work relevant terms in naturally; don't stuff them.
  • Call to action — tell viewers what to do next, lower in the caption.

Good titles and descriptions are how people find your videos, so it's worth shaping that first line with intent.
