Have you ever thought about how YouTube viewers find your content? 

Typically, they find it by typing specific terms, called keywords, into the YouTube search engine. If your video matches or is relevant to those terms, YouTube will rank it higher up in the search results.

To rank for certain keywords, you must insert them throughout your video metadata. Metadata is the text that describes your video and mainly includes the title, description, tags, thumbnails, and captions.

But before you can place keywords, you have to know which ones to use. That’s where keyword research comes in! 

Across the internet, you’ll find a wide variety of tools, both free and paid, that do the hard work of keyword research for you. In this article, we’re bringing you 15 of the best keyword research tools for YouTube that are available in 2024.

Before we delve in, let’s clarify the concept of YouTube keyword research.

What is YouTube Keyword Research?

When you research keywords, you’re looking for terms that users commonly enter in the YouTube search bar to find the videos they’re looking for.

If you learn what some of those terms are, you can include them in your video metadata to improve your chances of ranking higher in search results. The higher you rank, the more views you’re likely to generate. The entire process is known as YouTube keyword research, involving finding, analyzing, and selecting keywords for effective YouTube search engine optimization (SEO).

Let’s say, for example, you plan to make a video showing how to build a table. To research keywords related to this topic, you would enter the topic into a keyword research tool, and the tool would pull up dozens if not hundreds of results. These are the terms that users are searching for when they want to know how to build a table, and the terms at the top of the list are the ones that are being searched for the most.

Referring to this list, when selecting a YouTube keyword, consider relevance, search volume, competition, audience intent, and trends. Ensure the keyword aligns with your content, has a good search volume, manageable competition, and reflects current interests.

A keyword research tool is also helpful if you’re not sure what topic you want to make your next video about. Just research general topics that you’re interested in and see what popular keywords come up. Then base your video on those top search terms.

If you’ve never used a keyword research tool before and don’t know where to start, we’ve got you covered below!

3 Tips For Conducting YouTube Keyword Research Effectively

You can have the most comprehensive, most expensive keyword research tool that exists. But if you don’t know how to use it to optimal effect, it doesn’t matter how many features it comes with – it’s not going to help you rank your content and grow your channel. Here are three tips that will take your keyword research to the next level:

1. Start With a Seed Keyword

Rather than get super specific with your research, start with a seed keyword. 

A seed keyword is a short, one or two-word keyword that describes your video topic or niche on a broad scale. It’s designed to help you discover a wider range of longer-tail keywords and sub-topics, which you can then use as content ideas or as tags for your existing videos. 

2. Use the Metrics to Your Advantage

Metrics such as search volume, competition level, CPC, and trends data are crucial to helping you find the most effective keywords for your topic or seed keyword. Use them to your advantage, and to figure out which keywords will generate the most views for your video.

3. Pay Attention to Your Competitors

Sometimes, your competitors provide you with the most insight for keywords to use (and not to use). Analyze the other creators in your niche to find out which keywords they’re using to rank their content that’s similar to yours.

Bonus Tip: In addition to researching a topic or keyword, research-related or alternatively spelled versions of it, as well. This can help you catch a variety of keywords that users might type in to look for your content.

How To Extract YouTube Keywords From a Competitor’s Video?

Another way to perform keyword research is to extract the keywords from one of your competitor’s videos that’s similar to yours (or to a video you intend to create in the future). 

To do this, you need a tool called a YouTube tag generator (or a YouTube tag extractor), which reveals the keywords that another creator uploaded as tags on their video. All you have to do is input the video’s URL into the tag generator, and it will produce the list of keywords you’re looking for. Here are the few examples of YouTube tag generators that are free to use on your mobile device:
