H-Supertools YouTube Keyword Tool – Free Forever

If you aren’t new to H-Educate, you already know I own H-Supertools. But that’s not the reason I’ve chosen it for this post. Rather, I’ve enlisted H-Supertools’ YouTube Keyword Tool because it’s free forever. And it has a reliable data background as well. 

You can use the tool without registering yourself on H-Supertools. For that, all you need is to enter a seed keyword into the search box and click ‘Search. For example, I have entered ’email marketing’ into the keyword research tool.

And I got to know:

  • The search volume (which is 408K per month for the keyword)
  • Difficulty (a pretty low 2.32 for ’email marketing)
  • Related keywords, including their monthly volume and difficulty

The awesome thing about H-Supertools’ keyword research tool for YouTube is that you can copy the keywords and export them to CSV. So if you want to create your YT channel, you may want to enter a seed keyword and cover all the relevant keywords.

So if you’re looking for no BS keyword tool for YouTube, I believe MorningFame is a solid choice. And it’s reasonably priced as well.

Final Thought:

Jump on H-Supertools YT Keyword Tool, enter it into the YouTube search bar, and go with the auto-suggested keywords. Trying Google Trends will also be helpful. Go for MorningFame if you want one tool to do it all. is based on a freemium business model with many useful keyword tools, including the one for YouTube. When you enter a seed keyword into the search box, you get relevant keywords with their volume, trend, CPC, and competition.

The ’email marketing tutorial’ result has 2000 monthly search volumes with $21.73 CPC and 27 competition, which is low according to the tool. 

You can also use the ‘Negative Keywords’ feature, which helps you exclude unwanted words or phrases from your keywords. For example, if you are looking for keywords about a fruit called ‘apple,’ then negative words should be ‘iPad,’ ‘iPhone, or ‘MacBook.’’s YouTube keyword tool also divides your keywords into questions, prepositions, and hashtags. It’s helpful when you’re looking to prioritize your content. Sorting the keywords with ascending or descending order is also seamless on 

Final Thought:

Keyword Tool Pro offers a lot of value in terms of keywords’ volume and competition. And I believe it’s a super helpful tool to boost your YouTube success. But it’s a little more on the pricey side, and the plan starts from $69/month and goes on to $159/month. 

vidIQ – Best Chrome Extension for YT

It’s a free Chrome extension with a paid version as well. The keyword tool shows data within YouTube, which means you don’t need to go outside of YT. It’s quite similar to TubeBuddy and shows search volume, competition, related keywords, stats, keyword score, and more. 

When looking for competition, vidIQ doesn’t have a particular formula. But they state that they look at the total amount of engagements across social media, view velocity, and views. The stats are somehow identical to TubeBuddy. 

vidIQ gives you the ability to import all the video tags to CSV with just a click. It shares the tags of any YouTube channel. And it also recommends tags for your video. If you go to a channel’s page, you will see the ‘Trending’ tab.

The tab allows you to discover the newly published videos and how they’re performing on YouTube. The pricing is simple, the Basic plan is free, Pro starts from $7.5/month, and Boost starts from $39/month.

Ahrefs Keywords Explorer for YouTube

Keywords Explorer by Ahrefs uses over 640 million YouTube keywords, which is phenomenal. You enter your seed keyword and get valuable data from clickstream like global and local volume to clicks and more. 

You can see how many people search for a keyword on YouTube every month. And you can also get to know how many people click on a video after searching for a particular keyword.


Ahrefs allows you to export all the data to CSV or other file formats. You’ll never run out of ideas if you buy a subscription from Ahrefs. Why? It’s because it has tons of keyword ideas for almost every keyword in the world. 

Final Thought:

Digging Ahrefs’ Keyword Explorer can be gold for YouTube growth. If you already have an Ahrefs subscription. But I wouldn’t recommend buying the subscription solely for YouTube keyword research. 

Google Trends shows interest in a topic over some time in a particular region of the world. It’s free and yet extremely valuable at the same time. You can see which topics are rising on YouTube comparatively. 

For example, when I search for ’email marketing in the US, I get this result:

Google Trends for 'email marketing'

As you can see, you can select a particular country or the entire ‘world.’ For researching YouTube only, select ‘YouTube Search’ from the last tab. If the topic shows consistency in the graph, you should make a video on it.

Google Trends as a YouTube Keyword Tool in 2021

You can also compare between two or more keywords to see which one has more interest. For example, from Google Trends, I concluded that people search for email marketing more than content marketing. 

Google Trends for Youtube Keyword Research

What I like about Google Trends the most is that it gives you a comparison breakdown by subregion. For example, Nevada, Arizona, and New York are the subregions with the most interest in email marketing. Also, it shows some related queries as well. 

Final Thought:

My final thoughts about Google Trends for YouTube keyword research are positive. No matter what, you must always use the tool to decide on the topic or keyword for your YT videos. 

YouTube Autosuggest (Not a Tool, But Worthy YT Feature)

Nothing is better for YouTube keyword research than its platform. Hover over to the YouTube search bar and enter your seed keyword without pressing search for it. YouTube suggests a few keywords related to your seed keyword. 

And if you use the YouTube Auto-Suggest feature, you’ll not need to go further down the road. It will give you all the keywords that people are using to watch videos. Benefiting from the long-tail keywords for YouTube, success can be phenomenal without a doubt. 

YouTube Auto Suggest

Unfortunately, YouTube doesn’t give you any information like monthly search volume. For that, I recommend using H-Supertools’ YouTube Keyword Research Tool. It’s free and lets you know the volume and ranking difficulty in seconds. 

Final Thought:

YouTube Auto Suggest is a must when you are looking to make videos on YouTube. It’s free. And it’s gold because of authenticity. 

Making videos on targeted keywords with substantial search volume and low ranking difficulty is a recipe for YouTube success. Targeting trends may also help grow your YouTube channel. And I can say this because I have seen this on my YouTube channel, having 400K followers and tons of views. 

So, I highly recommend using the tools I have shared here in the post. Let me give you direct suggestions if you feel overwhelmed with the list. Do you want to go free forever? Choose H-Supertools’ YouTube keyword tool and Google Trends. 

Do you want to enjoy a premium tool? Get started with TubeBuddy because it has plenty of useful features without a doubt. Are you into digital marketing and have an Ahrefs subscription already? Then, hover over to ‘YouTube’ in Keyword Explorer.
