How to Write YouTube Descriptions That Rank [SEO Guide]

Your YouTube description is one of the most powerful SEO tools at your disposal—yet most creators completely waste it. While everyone obsesses over titles and thumbnails, the description box offers 5,000 characters of ranking potential that directly influences whether YouTube and Google show your video to viewers.

This comprehensive guide will show you exactly how to write YouTube descriptions that rank, drive traffic, and convert viewers into subscribers.

Why YouTube Descriptions Matter for SEO

YouTube descriptions serve three critical functions:

1. Search Engine Ranking

• YouTube's algorithm reads your description to understand video content
• Google indexes descriptions for traditional search results
• Proper keyword usage signals relevance to both platforms

2. Viewer Experience

• Descriptions provide context before someone clicks
• They offer additional value (links, resources, timestamps)
• Well-written descriptions increase watch time and engagement

3. Conversion Tool

• Strategic CTAs drive specific actions
• Links direct traffic to your website, products, or other videos
• Affiliate links can generate passive income

According to YouTube's official recommendations, descriptions should be at least 200 words and contain your primary keywords within the first 150 characters.

The Anatomy of a Perfect YouTube Description

First 150 Characters: The Critical Zone

The first 150 characters appear above the "Show More" button—this is your description's most valuable real estate.

What to Include:

• Your primary keyword (naturally, not stuffed)
• A compelling hook that makes viewers want to read more
• Clear value proposition of what the video delivers

Example (Bad):

In this video, I talk about how to grow your channel and get more subscribers. Watch to learn more!

Example (Good):

The second example includes the primary keyword ("YouTube SEO Strategy"), provides specific value (0 to 100K in 12 months), and creates intrigue.

Main Description Body (150-300 words)

After the critical first 150 characters, expand on your video's value:

Paragraph 1: Detailed Overview

• Expand on what viewers will learn
• Include 2-3 secondary keywords naturally
• Address the viewer's pain point directly

Paragraph 2: What's Covered

• Bullet points or numbered list of main topics
• Each point should include relevant keywords
• Make it scannable and easy to digest

Paragraph 3: Who This Is For

• Define your target audience
• Use language your ideal viewer uses
• Include demographic or psychographic keywords

Example Structure:

Links Section: Strategic Placement

Position your most important links after the main description but before timestamps:

Priority Order:

1. Your Primary CTA (course, product, service)
2. Free Resource (lead magnet, template, guide)
3. Social Media (Instagram, Twitter, TikTok)
4. Related Videos (internal linking for session time)
5. Affiliate Links (disclosed properly)
6. Website/Blog (traffic driver)

Pro Tips:

Hashtags: The Final Touch

YouTube allows up to 15 hashtags, but only the first 3 appear above your title.

Best Practices:

• Don't use misleading or spammy hashtags

Example:

#YouTubeSEO #VideoMarketing #ContentCreator #YouTubeGrowth #SEOTips

Keyword Research for Descriptions

Finding the Right Keywords

Step 1: Identify Your Primary Keyword

Your primary keyword should:

• Include long-tail variations

Tools to Use:

• YouTube's autocomplete (free)
• Google Trends (free)

Step 2: Find Secondary Keywords

Identify 5-10 related keywords to include naturally throughout your description:

• Questions your audience asks
• Long-tail variations

Example for "YouTube SEO" video:

• Primary: "YouTube SEO strategy"
• Secondary: "video optimization," "YouTube algorithm," "rank YouTube videos," "YouTube search," "video SEO tips"

Keyword Placement Strategy

Density Guidelines:

• Primary keyword: 3-5 times total
• Secondary keywords: 1-2 times each
• Keyword density: 1-2% of total description

Strategic Positions:

1. First 150 characters - Primary keyword once
2. Main body - Primary keyword 1-2 more times
3. Timestamps - Primary and secondary keywords
4. Hashtags - Primary keyword

Common Description Mistakes to Avoid

Mistake #1: Keyword Stuffing

What It Looks Like:

YouTube SEO YouTube SEO YouTube SEO tips tricks YouTube SEO guide YouTube SEO strategy YouTube SEO tutorial YouTube SEO optimization YouTube SEO best practices...

Why It Fails:

• YouTube penalizes obvious keyword stuffing
• Terrible user experience
• Makes your channel look spammy
• Can trigger manual review/penalties

The Fix: Write naturally for humans first, optimize for search engines second.

Mistake #2: Copying Old Descriptions

Many creators use the same generic description for every video:

Problems:

• Misses video-specific keywords
• Wastes ranking potential
• Confuses viewers and algorithm
• Reduces relevance signals

The Solution: Customize each description to the specific video's content while maintaining your brand elements.

Mistake #3: Ignoring the First 150 Characters

Treating the beginning like filler text:

Example of Wasted Potential:

Hey guys! Thanks for watching this video. Don't forget to like and subscribe if you enjoyed it. Let's get into the video...

Lost Opportunities:

• No keywords for ranking
• No hook for viewer interest
• Generic content that could apply to any video

Mistake #4: No Call-to-Action

Descriptions without CTAs miss conversion opportunities:

What to Include:

• Primary CTA (subscribe, visit website, buy product)
• Secondary CTA (free resource, social follow)
• Engagement CTA (comment question, poll)

Mistake #5: Broken or Missing Links

Common Issues:

• Outdated links to deleted/changed pages
• Shortened links that expired
• Missing tracking parameters
• No disclosure for affiliate links

Best Practices:

• Test all links before publishing
• Use branded short links (bit.ly custom domain)
• Add UTM parameters for tracking
• Include FTC disclosure for affiliates
