Frequently asked questions
How long should a YouTube description be?
YouTube descriptions can be up to 5,000 characters. The first 150–157 characters appear in search results without being cut off, so front-load your primary keyword and hook there. A good target length is 250–500 words total — enough for keywords, links, and timestamps without being spammy.
Do keywords in YouTube descriptions help with ranking?
Yes — YouTube's algorithm reads descriptions to understand what your video is about. Include your primary keyword in the first 2–3 sentences. Sprinkle secondary keywords naturally throughout. However, over-stuffing keywords makes descriptions unreadable and can hurt performance.
Why should I add timestamps/chapters?
YouTube chapters (added via timestamps in the description) create a clickable table of contents on your video. This improves viewer experience, increases average watch time by helping viewers find relevant sections, and can appear as individual search results in Google.
Should I put hashtags in the description?
Yes — up to 3 hashtags appear above your video title (the first 3 used). YouTube allows up to 15 hashtags in descriptions. Relevant hashtags help your video appear in hashtag search results. Don't use more than 15 as YouTube may ignore all of them.

The first 150 characters matter most
YouTube shows the first 150–157 characters of your description in search results — the rest requires clicking "Show More". Lead with your primary keyword and a compelling hook in those first two lines. Many creators write their description hook like a meta description: keyword-rich, compelling, and actionable.
