YouTube is the second largest search engine in the world. Therefore, keyword optimization of your videos on the platform is just as important as keyword optimization of your blog posts for Google.

Even if you’ve just made the next “Charlie Bit My Finger” video, remember that an algorithm dictates which videos YouTube makes available to the audience – and which not.

One of the best ways to keyword-optimize your videos for YouTube is to use tags. Below, we’ve put together a guide that explains exactly what YouTube tags are, why they’re important, and what best practices to follow.

What are tags for YouTube?

YouTube tags are words and phrases that you can include in the description of your YouTube videos. They let your viewers and YouTube know what your videos are about and can help them rank higher in the platform’s search results.

Why are YouTube tags important?

YouTube tags help YouTube understand the content and context of your video. This allows YouTube to understand the subject and category of your video and associate it with similar content, increasing the reach of your video. The rise in semantic search has made YouTube tags less important over time, but they’re still a strategic element that you can use to your advantage.

Although YouTube websites have a title, thumbnail, and description that are more important to video SEO on their platform, studies suggest that there is a slightly positive relationship between keyword-optimized tags and ranking (backlinko). Your neglect isn’t a deal breaker, but it can definitely help.

They’re even more important in cases where your target keyword is misspelled a lot because you can flag the misspellings without including them in your title and description.

As a secondary benefit, tags even help you organize and find your own content when creating self-reference tags (e.g. “Ireland trip 2019”).

YouTube tags best practices

Read these tips and tricks to get the most out of YouTube tags.

1. Make your first day your target keyword and rank the rest by importance.

YouTube takes the first few tags of your video into consideration when ranking content in search results, especially the first day. So make sure that your first day is exactly the keyword that you want to target.

2. Use some general keywords that describe the high-level topic your video falls under as other tags.

By using common keywords rather than other tags, YouTube can better understand the context of your video. For example, if you’re creating a video titled “How to Beat a Baseball,” you might want to add “Baseball” as a wide tag to indicate to YouTube that the overarching topic of your video is Baseball.

3. Use certain keywords that describe the topics covered in your video as other tags.

By using certain keywords that describe the topics you are covering in your video as other tags, YouTube can better understand the content of your video. For example, in the same “How to Hit a Baseball” video, if you add the addition of “Teeing Off” or “Hitting Hitting Practice” as specific tags, YouTube will see the exact topics covered in your video.

4. Keep most of your tags between 2-3 words.

While you should definitely include long-tail keywords and some broad match variations, YouTube seems to prefer 2-4 word phrases (Briggsby).

5. Don’t go overboard with tags.

The purpose of tags is to help the algorithm understand what your video is about so that it can be displayed to users looking for a video like yours. Using too many keywords can lead to confusion about what your video is actually about. Research suggests that the optimal number of tags is between 31 and 40 (if used correctly, of course). More than that dilutes their power.

6. Get inspiration from videos that are currently in the ranking.

When you know what you want to rank for, take notes from those who already rank the topic. Your keyword tags may be a great starting point for research and inspiration.

7. Get inspiration from YouTube Auto-Suggest.

Auto-suggest is a feature that helps users find what they need. YouTube doesn’t easily come up with these suggestions. There is a possibility that these keywords will be suggested. So don’t be afraid to go straight to the horse’s mouth, so to speak, and be inspired.
