What Are YouTube Tags?

YouTube tags (also known as “video tags”) are words and phrases used to give YouTube context about a video. Tags are considered an important ranking factor in YouTube’s search algorithm.

Why are Tags Important?

Like any piece of metadata, your tags are an opportunity to give YouTube and Google information about your video… including your video’s topic, category, and more.

And a recent industry study found a small but significant relationship between YouTube tags and ranking in YouTube:

With that, here’s how to optimize your video tags.

Best Practices

First Tag = Target Keyword

When it comes to video SEO, YouTube pays special close attention to your first few tags.

(Especially your very first tag)

First tag equals target keyword

So make sure that your first tag is the exact, word-for-word keyword that you want to rank for.

For example, let’s say you want to rank your video for the keyword “public speaking tips”.

You’d want to make your first YouTube tag that exact term:

Keyword tag

Use a Mix of Broad and Focused Tags

Focused tags (like “get bigger biceps” or “how to start a blog”), help YouTube figure out your video’s specific topic.

But it’s important to use broad tags too. Broad tags help give YouTube important context about your video.

For example, let’s say the primary keyword for your video is: “how to do a pushup”.

You’d want to use that keyword (and variations) in your tags:


You’d also want to throw in a couple of broad tags that describe your video’s broad category or high-level topic. In this case, broad tags would be terms like “fitness” and “workouts”:

Don’t Go Overboard With Tags

Stuffing videos with dozens of tags is a mistake that lots of new YouTubers make.

As it turns out, this can do more harm than good.

Remember: tags are designed to help YouTube understand your video content. And if you hand them 20+ tags, they’re going to have a hard time knowing what your video is actually about.

For example, check out the YouTube tags on this video:

Too many tags

Imagine that you’re YouTube. Based on these tags, what would you say this video is about? One tag says that the video is about blogging. But it’s also about life lessons and CSA?

If you’re confused, YouTube is confused. So if you overload your video with tags, you’re only going to hurt your rankings.

Instead, stick to 5-8 tags that accurately describe your video’s topic. These should be a mix of focused and broad keywords that you found from video keyword research.

For example, check out the #1 result for “passive income”:

Good amount of tags

This video uses 8 total tags that describe the video content. Simply, yet effective.

Use YouTube Tags That Are 2-3 Words In Length

How long should each of your tags be?

According to data from Briggsby, the best tag length for SEO is 2-3 words.

YouTube average views by number of tags

Does this mean you should make sure every single tag is in this exact range?

Of course not.

In fact, in some cases (like with broad tags), it makes sense to use really short, 1-2 word tags.

That said, this data does give you a rough idea of how long tags should be in general.

Are your tags too short? That may not be enough information for YouTube.

Are your tags too long? That might give YouTube information overload.

For example, let’s say you just made a video about: “the health benefits of coffee”.

Instead of a group of single-word tags like “coffee” and “health”, use descriptive tags like: “coffee health benefits” and “is coffee healthy”.

Generate Tags With Tools

Nothing’s worse than staring at your screen trying to come up with tags to use on your latest video.

That’s not only annoying, but bad for SEO too.

Tips and Advanced Strategies

Read Your Tags: Try reading your tags without looking at your video title or description. Would you be able to understand your video based on tags alone? If so, you probably have an awesome set of tags on your hands.

Add Long Tail Keywords: If you have room, add 1-2 long tail variations of your target keywords as tags.

For example, you’re about to upload a video optimized for: “chili recipe”.

Type that keyword into YouTube and see what they suggest:

Chili recipe suggested

These suggestions are perfect long tail variations of your keyword to use as tags.

Use Accurate Tags: Some people add their competitors’ YouTube channel names as tags (the idea is that this can help you show up next to videos from that channel as a Suggested Video). Some people also use the name of a celebrity as a tag for the same reason. While this might work, it’s risky. According to YouTube, misleading tags can get your video taken down.

Track Your Performance: You’re using tags in order to improve how your videos’ rank, so tracking the rank and then acting on it will help you grow faster.

Copy Tags From Popular Videos: Tags aren’t only important for YouTube Search. They also help you rank as a Suggested Video. Specifically, if your tags match the tags of a popular video, you can show up next to it.

Find popular videos on your topic copy a few relevant tags

So feel free to use a few relevant tags from a popular video as your tags.
