How to Optimise a YouTube Video
Title
Include your target keyword near the start. Keep under 60 characters. Make it compelling — "How to Fix [Problem] in 5 Minutes" works better than "[Problem] Tutorial".
Description
First 2-3 lines are crucial — they show in search results. Include your keyword naturally, then add a detailed description with timestamps, links, and related content. Aim for 200+ words.
Tags
Add your target keyword, variations, and related terms. Start with exact match, then broaden. 10-15 tags is typical.
Thumbnail
Custom thumbnails get significantly more clicks than auto-generated ones. Use high contrast, readable text, and faces. 1280x720 pixels minimum.
Chapters
Add timestamps in the description to create chapters. This helps viewers navigate and improves engagement metrics.
Closed Captions
Upload accurate subtitles. YouTube can index the text, and it makes your video accessible to more viewers.
