Practical guide

Make the title and thumbnail work together

On YouTube, viewers decide from a thumbnail and a title before they read anything else. The preview shows both in a 16:9 card, with your channel name and the first lines of the description.

Titles are truncated differently on each surface, and the description is shown in full only on the watch page. Confirm the final result in the PostlyBee composer for the connected channel.

Privacy: Your copy, account details, and any image you add stay in this browser tab. Nothing is uploaded to PostlyBee or an AI service.

Pro tips

Pro tips for YouTube posts

The first line is the title

The preview treats your first line as the video title and the rest as the description. Write a title that stands on its own.

Titles are cut off

Long titles are cut off in the feed and on mobile. Put the important words first and keep the title short enough to read in full.

The thumbnail leads

A 16:9 thumbnail takes up most of the card. Add one from your device to see how the title and image work together.
