What makes a high-performing YouTube description
First 2 lines are everything
YouTube shows only the first 100–150 characters in search results and on the watch page before the 'Show more' fold. Make them a hook that sells the click.
Chapters boost watch time
Adding timestamps that follow the format '00:00 Intro' triggers YouTube's automatic chapter feature — improving navigation, watch time, and the chance of appearing in chapter-specific searches.
Hashtags signal the topic
Adding 3–5 hashtags near the end of your description tells YouTube and viewers exactly which topic category your video belongs to, helping surface it in hashtag feeds.
FAQ
How long should a YouTube description be?+
Aim for 150–300 words. Long enough to include relevant keywords and context, short enough that viewers don't tune out. YouTube allows up to 5,000 characters, but the first 2–3 lines matter most.
Do YouTube descriptions affect SEO?+
Yes — YouTube's search algorithm indexes your description text. Including your target keyword and related phrases in the first 100 characters improves your chance of ranking for those terms.
Should I include hashtags in my description?+
Yes. Add 3–5 relevant hashtags near the end of your description. YouTube picks up the first three and displays them above your video title, which can drive additional hashtag-search traffic.
What should the first line of a YouTube description say?+
It should be a hook that gives the viewer a compelling reason to watch — essentially a second title. Avoid starting with your channel name or links. Lead with value or a curiosity gap.
