Introduction

YouTube is the world’s second largest search engine — and most content creators ignore the SEO aspect entirely. By optimising your videos for search, you can earn views for months or years after uploading, rather than relying entirely on your existing subscribers. Here’s everything beginners need to know about YouTube SEO.

Keyword Research for YouTube Videos

YouTube keyword research differs slightly from Google keyword research. Use YouTube’s search bar autocomplete to find popular search terms. Look at what terms your competitors rank for. Use TubeBuddy or VidIQ (both have free tiers) to see search volume and competition scores for YouTube-specific keywords. Target longer, specific keywords rather than broad ones.

Optimise Your Video Title

Your video title is the most important SEO element. Include your target keyword near the beginning. Make it compelling and specific — tell viewers exactly what they’ll learn or get from watching. Keep it under 60 characters so it doesn’t get cut off in search results.

Write a Keyword-Rich Video Description

YouTube’s algorithm reads your video description to understand what your video is about. Write at least 150-300 words in the description. Include your target keyword in the first 2-3 sentences. Include related keywords naturally throughout. Add links to related videos, your website, and social channels. The first 125 characters appear in search results without clicking ‘show more,’ so make them count.

Tags, Categories, and End Screens

Add 5-10 relevant tags including your exact target keyword and close variations. Choose the most relevant category for your video. Use YouTube’s Chapter feature to add timestamps for longer videos — this improves watch time and helps YouTube understand your content’s structure. Add end screens to your last 20 seconds promoting related videos to reduce drop-off.

Thumbnails: The Most Underrated SEO Factor

Click-through rate is a major YouTube ranking factor — and thumbnails drive click-through rate more than anything else. Create custom thumbnails with high contrast, bold text, expressive faces, and clear visual branding. Your thumbnail and title work together as a promise to the viewer. Consistently designed thumbnails also build channel brand recognition over time.
