by Matthias Funk | | Category: YouTube Marketing

Did you know the description of your YouTube video is just as important as the video itself? It is…but do you know why? Because the YouTube description is the best way to control the searchability of your video and boost your video’s (and channel) SEO and YouTube rankings. How well you craft and design your YouTube descriptions, YouTube hashtags, and use your keywords, etc. will determine where your videos rank…or not.

What? You don’t know how to write a YouTube description?

No worries! That’s what we’re here for. So let’s get started!

We are going to start with the basics and walk you through the entire process. By the time you get to the end of this text, you will be a pro at writing a YouTube description that is intriguing… and ones that will have a positive effect on your SEO and YouTube rankings.

What Is a YouTube Video Description?

The YouTube video description provides a detailed overview of the video’s content.  What you put in the YouTube description box will help viewers understand what your video is about, as well as playing a major role in your YouTube SEO and rankings within the YouTube Search Engine – but only if it’s done right.

Where Is the Description Box on YouTube?

On YouTube, the description box is underneath the video and below the line where you see the title, the number of views, likes, shares, etc. On mobile devices, the description text is hidden by default. Just take this video of the Cute Life Hacks channel as best practice of how to write a YouTube video description:

When you compare how the description of this YouTube video gets displayed across devices you see some differences:

Both on a desktop and on mobile the full description text gets displayed. On desktop, you just have to click on the “Show more” link. On mobile, you just have to click on the arrow icon next to the video title.

Then, underneath the description box will be the comments about the video, if you have that feature enabled.

Parts of the description get displayed in search results as well, at least on the desktop.

Why Is A YouTube Description So Important?

A YouTube description is important because this is the space you will use to grab the viewer’s attention and tell them what your video is about. It’s also the place where you will enter your hashtags and keywords into the verbiage to help boost your SEO, YouTube rankings, and try to get more subscribers. The first three hashtags you enter will be automatically placed above the title so your viewers can click on them to watch other related videos.

How Do I Write the Text for a YouTube Video Description?

The best way to approach writing the text for your YouTube video description is to concentrate on writing it for people, not search engines. Yes, there are portions of the description where you will need to think about the SEO aspect of it; however, that should not be your main focus.

When writing the text for your YouTube video description, you should include the following:

  • Relevant text describing your video, your channel, and your brand. This needs to be intriguing enough to get viewers interested enough to want to watch your video, comment on it, subscribe, and share it with others when they are done.
  • A well-crafted call-to-action (CTA) telling your viewers exactly what it is you want them to do after they’ve watched your video. For example: “Click Here Now for a Free Marketing Guide” or “Contact Us Today to Receive Three Free Lessons.”
  • Focus on the first three lines of your text. The first three lines are the most important because these are what is displayed without having to click the “Show More” link. So you need to make the best of this area by presenting your keywords, hashtags, and the text you choose (naturally) because you need to create enough interest so the viewers will want to watch your video and watch it all the way to the end.

What Links Should I Include in My YouTube Description?

Every YouTube description you write should include the following links:

A Subscribe Link for Your Channel

Adding a YouTube subscribe link is easy. To create it you just have to make sure that your YouTube channel has its own ID (for example, the tubics YouTube channel ID is UCoSK_V3cwHyMNBTvzwfOELQ), then replace the channel ID in the following URL with yours.

If your channel has a custom channel URL and not a channel ID, your channel URL would have /user/ in it instead of /channel/), then format the URL slightly differently.

If someone clicks on this link in your video description, they will be taken to your YouTube channel. If they are not already subscribed, they’ll see a pop-up asking them to subscribe.

Links to Specific Video Parts

Especially for longer videos, it’s often handy to link to a specific point in the video. Just add a time stamp to the end of the URL, something you can do manually or automatically. When the link is clicked and the video is opened on YouTube, it will start at the specific time you’ve decided. Read how to add these below.

Links to Other Social Media Channels

Since YouTube most often is not your only channel to communicate with your audience you should also link to these channels: i.e. your other social media channels or your website.

Links to Related Videos, Playlists or Blog Posts

Many channels also link to other videos for SEO reasons. YouTube’s Creator Academy officially recommends linking to relevant playlists.

Affiliate Links (if applicable)

It’s important to include the above-mentioned links so the viewers can click on them to find more information and/or make a purchase before or after watching your video.

Don’t forget to put the http:// or https:// prefix in front of all web addresses to make them clickable. If you just type it won’t be a clickable link.

What Tags/Keywords/Hashtags Should I Include in My YouTube Description?

The tags, keywords, and hashtags are what YouTube uses to determine what your video is all about and how it determines your video’s ranking.

“YouTube is one of the largest search engines in the world. And writing a description with keywords can help viewers find your videos more easily through search.” YouTube Creator Academy

Your description should include the following:

  • Main keywords/tags (1-2) in the first sentence.
  • Keywords should be visible in the SERP snippet (we will talk about this in a moment).
  • Related keywords.
  • Related hashtags.

In addition, you should never type a string of keywords/tags in your description and avoid using irrelevant keywords. If you do, your video could be penalized or banned.

Why Is It So Important to Pay Attention to the SERP Snippet?

The SERP snippet is a few lines of data that are displayed as text on a search engine results page such as Google and YouTube.

Here are some of the YouTube best practices for how to make the most of the SERP snippet.

  • Your main keyword should be in the first sentence in the visible area (not where it can only be seen after clicking the Show More link).
  • Always place your call-to-action (CTA) in the first one or two sentences where it is visible before the text cuts off.
  • The easiest way to make sure your SERP snippet is perfect is to use a SERP preview tool.

How Many Characters of a YouTube Description Are Visible?

The number of characters of the YouTube description that are visible on a search results page will vary depending on the search engine you are using.

Here are the current number of visible characters of a description on the search results page for:

  • Google Search:  150 to 160 characters are visible, including the spaces.
  • YouTube Search: 138 characters are visible on desktop, including the spaces.
  • YouTube Watch Page: 5,000 characters are available for the description, but only the first few lines will be visible before having to click on the Show More link where the rest of the description can be read. On smartphones not even the first few lines get displayed, only the title is shown.

How Long Should a YouTube Description Be?

YouTube gives you 5,000 characters (about 800 words) for the description; therefore, you should use every bit of it, or at least make it as long as possible. Just remember to keep the text relevant to your video.

the length of a youtube video description can be up to 5000 characters

Also, be sure to include some hashtags and don’t forget to add your keywords at a rate of about 1-2%.

HOT TIP: Some people add the transcript of their video for the description and a link to the original transcript if the entire transcript doesn’t fit within the description box.

How Should I Design My YouTube Description?

When designing your description for the YouTube description box, you should try to find ways to make them stand out such as using ASCII characters and symbols like the arrow on both sides of a word or phrase. You can also structure paragraphs with separator lines. Anything you can do to make your text easier to read and your important information to stand out.

What Should I Avoid When Designing My YouTube Description?

YouTube is very clear about what should be avoided when scripting your description.

  • Special characters like <> because YouTube doesn’t want you to write HTML code in the description.
  • Copyright infringement.
  • Hashtags that violate the YouTube Community Guidelines
  • Anything else that violates the community guidelines.

What About the YouTube Algorithms?

YouTube, just like any other search engine, uses algorithms to determine the rankings of the videos on their site. The way they do that is by looking at patterns so it’s important that you use some text paragraphs across all your videos to increase the chances that one of your other videos will be suggested after the current video your viewer is watching has finished playing.

How to Write a YouTube Video Description Efficiently

Five Quick Tips for Creating a Compelling YouTube Video Description

1. Make the most of the first three lines because this is the only part of the description that will be visible.

2. Create timestamps if your video is on the longer side because this will make it easier for the viewers to navigate the video.  Timestamps get entered in the format hour:minute:seconds such as 00:01:06 for 1 minute and 6 seconds into the video.

3. Include links to relevant sources. If you mentioned any tools, products, services, or other resource information on your video, consider including a list of them in your video’s description to make it easier for your viewers to find and access them.

4. If you used someone else’s music or someone else’s video under the fair use act, make sure you give them credit by mentioning them in your video’s description and include a link to their YouTube channel, social media pages, etc.

5. Always include YouTube hashtags to make it easier for your viewers to seek out more information. And, craft your hashtags in an attention-grabbing way. Just make sure you keep them relevant to your video and always follow the YouTube community guidelines.
