How to Write YouTube Descriptions Like a Pro (15 Tips)

When you upload a video on YouTube, your job is not done with just a good title and thumbnail. The description is equally important. Think of it as your video’s sales pitch—it tells both YouTube’s algorithm and your viewers what your content is about.

A well-written YouTube description:

• Improves your video’s ranking in YouTube and Google search results.
• Encourages viewers to watch till the end.
• Drives people to take action—like subscribing, sharing, or clicking links.
• Adds credibility and professionalism to your channel.

Yet, many creators either ignore it or write one or two random lines. That’s a big mistake. If you want to grow like a pro, you need to master the art of writing YouTube descriptions.

Here are 15 powerful tips that will help you do just that.

1. Start with a Strong Hook

The first 150 characters are the most visible part of your description. They appear in search results and before the “Show More” option. If you waste this space with filler text, you risk losing potential viewers.

👉 Example: Instead of writing “In this video, I talk about fitness”, try “Learn 7 simple home workouts that burn fat fast without equipment”.

2. Use Your Keywords Naturally

Your description should include the keywords people search for. This helps YouTube understand your video and recommend it to the right audience.

But avoid keyword stuffing. Write like you are talking to a friend.

👉 Example: If your video is about “digital marketing for beginners,” mention it naturally: “This digital marketing tutorial for beginners covers SEO, social media, and email marketing basics.”

3. Summarise the Video Clearly

Viewers want to know what they’ll get from your video. In 2–3 sentences, explain the main points. A clear summary increases watch time because people know what to expect.

👉 Example: “In this tutorial, you’ll learn how to edit YouTube videos using free software. I’ll show you step by step how to cut clips, add text, insert music, and export in HD.”

4. Place Key Info in the First Two Lines

Most people never click on “Show More.” That means you need to place your most important information (topic, benefit, or CTA) in the first two lines.

👉 Example: Start with: “Want to grow on YouTube? These 15 tips will help you write professional descriptions that improve SEO and boost views.”

5. Add Timestamps for Easy Navigation

Timestamps (chapters) make your video user-friendly. They also appear in Google search results. Break your video into sections with timecodes.

👉 Example:

0:00 Introduction  
1:25 Why Descriptions Matter  
4:10 How to Add Keywords  
6:50 Using Timestamps  
10:20 Call-to-Action Examples  

This small step can dramatically improve watch time.

6. Include a Call-to-Action (CTA)

Never assume viewers will take action automatically. Tell them what to do—like, share, subscribe, or visit your website.

👉 Example: “Enjoyed this video? Hit the like button, subscribe, and turn on the bell so you don’t miss future tips.”

7. Link to Related Videos or Playlists

YouTube rewards channels that keep people watching. By linking to your own related content, you increase session time.

👉 Example: “Watch next: [Playlist: YouTube Growth Hacks]”

8. Add External Links Smartly

It’s okay to promote your website, products, or social media. But do it neatly and avoid spamming. Always place external links after your video summary.

👉 Example:

• 🌐 Website: www.example.com
• 📲 Instagram: @yourhandle

9. Use Hashtags Strategically

Hashtags help your video appear in more searches. Use 2–3 relevant ones at the end of your description. Avoid overloading.

👉 Example: #YouTubeSEO #VideoMarketing #YouTubeTips

10. Optimise for Mobile Viewers

Over 70% of YouTube watch time comes from mobile. Keep your descriptions scannable with short sentences, spacing, and emojis (if suitable for your audience).

👉 Instead of a big block of text, break it into clear sections.

11. Highlight Collaborators or Mentions

If you’re working with another creator or brand, mention and link them. This builds trust and expands your reach.

👉 Example: “Special thanks to @JohnDoe for co-hosting this video. Check out his channel here: [link].”

12. Add Credits When Needed

If you use music, images, or external content, give credit in your description. It’s professional, ethical, and avoids copyright issues.

👉 Example: “Music by Audio Library: https://youtu.be/example”

13. Use a Template for Consistency

Having a description template saves time and keeps your channel organised. A good template includes:

• Intro hook
• Summary
• Timestamps
• CTAs
• Links (internal + external)
• Hashtags
• Disclaimers (if needed)

14. Add Social Proof or Achievements

People trust creators with authority. If your channel hit milestones or got featured somewhere, mention it briefly.

👉 Example: “Our channel has crossed 1 lakh subscribers—thank you for the support!”

15. Test and Analyse Performance

Every audience is different. Experiment with styles—short vs long descriptions, more vs fewer links—and then check YouTube Analytics.

Look at:

• Click-through rate (CTR)
• Average view duration
• Subscriber growth from that video

Then refine your descriptions accordingly.
