Keywordtool.io is a keyword tool for YouTube which is, without a doubt, one of the most powerful YouTube keyword tools available out there. It ranks hundreds of keywords by popularity and captures the data from YouTube auto-complete so that you can create lists of keywords using that data.

Along with the auto-complete data, you can also search for additional questions that the audience is asking. This comes off as a highly beneficial YouTube SEO tool.

However, the only shortcoming that this tool comes with is that it is fairly limited on the free version. But look at the bright side: once you upgrade it to Pro Basic, you will receive almost double the keyword results.

It will also let you compare the volume of searches made for those terms. To upgrade it to Pro Basic, you will require around $68 a year. This means that it is going to be something of a decent investment if you decide to go for it.


To get more data on particular keywords, you can use this keyword tool for YouTube called Ubersuggest. It is inspired by the SEO guru that is Neil Patel who is one of the best SEO Experts out there.

What this tool does is that it shows the search volume and competition of the keywords. Along with that, you can also see other information such as cost per click and the seasonality of the keyword. It is a free application with no limitations or whatsoever at all, that is why it is well worth checking out.

Google trends

One of the most highly recommended keyword tools for YouTube is Google Trends. It is a tool worth checking out for YouTube keyword research, because of its powerful, accurate, and, best of all, free properties!

This tool comes with various options that let you narrow down the trend results to just YouTube searches. This is a great way for gaining insights into your search terms.

Google Trends is also capable of narrowing down the results to a specific country, helping you to acquire insight into what your target audience is currently interested in.


The keyword tool present in VidIQ is one of the very rare research tools that have a function for YouTube built-in alone. In this tool, you can paste in the keywords you want to research and select the country you wish to target.

Once you do this, it will return all the search volumes and amount of competition and will rank your keywords based on these data and figures.

There is only one downside that this tool brings with itself which is that there is a fairly complicated subscription process to go through if you want to upgrade from the free version.

Fortunately, the free version is suitable for new users, but not quite for in-depth analytics. So if you are interested in that, you will have to upgrade it eventually.

Keyword Tool Dominator

Keyword Tool Dominator is one of those keyword tools for YouTube which has got a brand name to itself but it is very easy to use. It is a great place to start if you are a newbie in the world of YouTube keyword research. Just like in one of the previous tools, here you are supposed to enter your seed keywords first.

Once you do that, the Dominator will present a list of relevant keywords that are related to those terms. Now all you have to do is select the most useful ones and download them to your device.

However, there is only one drawback that this tool comes with which is that you can only perform three searches a day on the free version of this tool. Even though it is enough for a newbie like you, to begin with, you can always upgrade it to the unlimited version for better facilities. This will also give you access to the search volume results. This tool has comes with a one-off fee of $39.99.

YouTube Auto Complete

If you are someone who goes on YouTube a lot, then you probably already know what this is about. Whenever you go over to the search bar to search for something on YouTube, YouTube starts to suggest some keywords to finish your search. This process is called auto-complete. Now you may have a question: how does this work?

The answer is very simple: it works by suggesting the most popular keywords that start with the letters/words that you have typed so far. Through this, what YouTube is essentially trying to say is that those are the terms that are most frequently searched for the words that you have already typed. Is this the most effective method?

Yes. Is it also the easiest method? Definitely yes. This proves that it is a great place to start building your keywords. Even though it is not exactly a proper tool, it acts as a fantastic YouTube keyword tool for your videos.

All you have to do is start your search for your video (e.g. gifts for…) and notice what comes up as the suggestions. In this case, we can see that the most popular keywords are ‘boyfriend’, ‘best friend’, ‘brother’, ‘girlfriend’, and ‘mother’.

Keyword Keg

Keyword Keg is one of the most powerful and efficient keyword tools for YouTube out there. It offers lots of data and figures, obtained from a huge array of data sources including Wikipedia, Alibaba, Playstore, and others.

There are filters for country and language and you can address all your varied issues like buyer intent and product information. However, there is a downside that comes with this tool which is that there is a strict maximum limit on what you can do before you pay. In this case, you get to see the top five results before you upgrade to the paid version.


Kparser is one of those keyword tools for YouTube which comes to your notice very early. It can help you to find YouTube keywords for free use. Apart from finding the best high traffic core keywords, this tool can also give you suggestions on long-tail keywords in every field possible.

Once you use this tool, you won’t have to worry your head up about the fact that you can’t seem to find the right keywords to use in your video title, description, and tags. You can also select the country and language when searching for a YouTube keyword. When you are searching for more than one keyword, always remember to separate them with a comma.

SEO Chat

SEO Chat is one of the most amazing free keyword tools for YouTube. It can generate keyword ideas for every search engine – Google, Amazon, Bing and YouTube. This means that you are presented with two options – you can either search for keywords from all of those sources or you can just search YouTube alone to find your keyword lists.

To begin with, you will need a ‘seed’ keyword, such as ‘shoes’, ‘make-up’, ‘gifts’ or ‘marketing’. What happens then is that SEO Chat organizes the results alphabetically with a bunch of other letters following your seed keyword. Now all you have to do is simply scroll through the results. This will allow you to get loads of ideas for keywords and possibly content too.

This keyword tool also lets you further increase your results by choosing a particular keyword and running ‘part two’ of the process. In part two, the phrases get expanded even further than before. Lastly, you can also export your chosen keywords from the software and make them ready for use in your YouTube SEO tool.


The above-mentioned list of the 10 best keyword tools for YouTube requires a bit of trial and error as there is no YouTube keyword tool to find video result keywords yet. However, you can use Google to search your keywords and see if they are legit video result keywords or not. All you have to do is type them in, and see if a video appears in the listings below. If it does, then you have successfully discovered a video result keyword that is well worth optimizing for.
