YouTube SEO: Keywords, Metadata & Search Hacks That Still Work

January 12, 2026

YouTube is the second-largest search engine in the world, yet many creators underutilize its SEO potential. Posting videos without a strategy for keywords, metadata, and search optimization is like setting up a store in the middle of nowhere you might have amazing products, but no one sees them.

Understanding YouTube SEO

YouTube SEO is not just about adding keywords to your video title. It’s about signaling to YouTube exactly what your video is about and who it’s for, while ensuring the algorithm predicts strong engagement and watch time.

YouTube ranks videos based on multiple factors:

Click-through rate (CTR) on search and suggested pages
Watch time and retention
Engagement (likes, comments, shares, and saves)
Session duration (how long viewers stay on YouTube after your video)

Keywords: How to Find the Right Ones

Keywords are the foundation of YouTube SEO. They signal topic relevance to both YouTube and viewers.

Steps to find strong keywords:

Start with seed keywords — the topic of your video
Use YouTube autocomplete — see what people are searching
Check competitor videos — analyze top-performing titles and descriptions
Leverage tools like TubeBuddy, VidIQ, or Reachism insights for trending topics

Placement tips:

Include your primary keyword in the title
Add it naturally in the description
Use relevant tags, though tags are secondary signals today

Metadata That Still Works

Metadata includes your title, description, and tags, and it’s one of the most important ways YouTube understands your video.

Titles

Must include your primary keyword early
Should be clickable but clear, avoiding clickbait
Use numbers, “how to,” or problem-solving language

d) Optimize Thumbnails for CTR

Consistent branding
Faces, objects, or text overlays that match the keyword intent

Engagement & Retention Signals

SEO isn’t just keywords. YouTube cares how users interact with your video.

Watch time & retention: videos that hold viewers longer rank higher
Likes, comments, and shares: measure audience approval
Saves: shows value and increases long-term visibility

Repurpose Content for Maximum SEO

One video can power multiple assets:

Shorts for quick discovery
Clips for social media promotion
Blog posts for organic traffic

Using this approach increases keyword footprint and authority without creating new videos constantly.

Track & Optimize Continuously

SEO is not set-and-forget.

Track impressions, CTR, watch time, and retention
Update titles, thumbnails, and descriptions for underperforming videos
Experiment with keyword variations and metadata tweaks

Reachism can help creators analyze performance, suggest keyword optimizations, and monitor trends to keep your YouTube SEO strong.
