YouTube is more than just a platform for entertainment – it’s also a powerful search engine, second only to Google, and the second most visited website in the world.

As a result, smart marketers are focusing on YouTube SEO strategies, with one of the key components being the use of the right keywords.

YouTube keyword tools help eliminate guesswork and provide insights into consumer habits, giving businesses a potential edge over their competition.

In this post, we’ll explore the importance of YouTube keyword research and review 11 of the most popular tools available today. Let’s jump in!

What is YouTube keyword research?

Keyword research is an SEO best practice marketing pros use to find the most relevant search terms and discover other search terms people enter when looking for information. This research helps businesses understand what kind of keywords to work into website copy, page titles, tags and more, to help them optimise organic content discovery.

Specifically, as it relates to YouTube, keyword research is the process of discovering what search terms users type into the video platform when looking for content. How many people search for your keyword – and similar ones?

Once you know what your target audience is searching for, you can add those keywords to your video’s name, tags, description and transcript to boost your results and appear higher in YouTube SERPs (search engine results pages).

But more than this, you can be sure that you’re creating video content that you know your audience is likely to be looking for.

Our Insight
Businesses of all sizes, including one-man shops, local eateries and small businesses need to approach search engine optimisation thoughtfully and strategically. But not every business can afford to hire an SEO agency to do that work – which is why YouTube keyword tools, like the ones in this list, are so helpful.

1. TubeBuddy

TubeBuddy is a video SEO nerd’s best friend. This tool was designed to discover tags that are related to your search terms. In the below example, when exploring the search term “san diego surfing,” TubeBuddy shows users that there are many other popular video search terms like “san diego surfing beaches” and “san diego surfing season” that are trending. But the tool shows much more than that.


TubeBuddy’s dashboard also shows the overall score of your search terms, how competitive that term is, the total number of times that term was searched and more. And since it’s a light-weight Chrome extension, TubeBuddy isn’t just easy to use – it’s easy to install too. The best part: you can use the whole thing for free!

Pros: • Enhances YouTube SEO with robust features.
• We found it easy to navigate.
• Provides A/B testing for thumbnails.
Cons: • Free version is limited in functionality.
• Some features are behind a paywall.

2. VidIQ

VidIQ helps video content creators determine the best keywords for improving searchability. When you research a search term, VidIQ pulls data from YouTube to give you a look at what’s going on with that term. You’ll be able to see helpful information like recommended tags and what top-performing videos are currently displayed in SERPs.


If you want to get more granular, you can also use VidIQ to explore additional related keywords and look at search volume reporting in the past month or year, or even since YouTube was created.


This tool is great for helping marketers confirm whether they’re using the right keywords, explore new keyword options, and assess who they’re competing against for higher search rankings. VidIQ comes with dozens of other features designed for video creators, but the keyword research tool requires a subscription. However, at only $7.50 per month, it’s pretty affordable for even small businesses on tight budgets.

Pros: • Offers comprehensive competitor analysis.
• We achieved higher engagement with their recommendations.
• Useful video optimization tips.
Cons: • Interface can be overwhelming for beginners.
• Limited features in the free version.
• Pricey for full access.

3. Ahrefs


Ahrefs is a marketing analyst’s best friend. This tool has a huge collection of SEO, competitor analysis, keyword research and keyword identification functions to help you optimise your digital content. With clients like Facebook, Netflix, and Uber, you know it’s big time. We’re really impressed with the platform’s YouTube Keyword Tool, which pulls YouTube search volumes for keywords from up to 170 countries.


The tool is managed in a sleek, easy-to-use dashboard. Simply type your keyword in the search bar and Ahrefs pulls data from around the world to show you the total search volume for each term and how many clicks that search phrase earned.

If clicks are low, it might mean that users aren’t happy with the results they’re seeing; maybe they need an engaging video from you to be satisfied with their search results. Low clicks could also mean a video’s thumbnail, title, and description aren’t interesting enough for people to bother clicking on them; for more on that, check out this post.

Ahrefs also pulls a few other interesting data points, including relevant search phrases that use your keyword and other keywords or phrases that are relevant to your term, making this tool not just a research platform but a keyword generator, too.


Ahrefs offers four pricing tiers, ranging from $99 per month for a single user to $999 per month for 5 users. It’s one of the more expensive options on this list, but if you’re serious about keyword research, it might be worth the investment. You should definitely take advantage of the tool’s 7-day trial for $7 to see whether you like it before you subscribe.

Pros: • Powerful backlink and site analysis tools.
• Extensive keyword research capabilities.
• Amazing suite of educational content to help educate users.
Cons: • Expensive compared to other options.
• Some features can be complex to use.

4. Keywordtool.io

Keyword Tool

When you search for a video on YouTube, the platform gives you a longer list of recommended results based on what other people searched for in the past. Keyword Tool leverages that data to help marketers like you improve your YouTube SEO.

Keyword Tool is a YouTube autocomplete keyword program that generates popular search phrases from base terms. For example, a company that makes clothes for toddlers and infants might regularly use the term “baby clothes” as a keyword.

Keyword Tool

After using Keyword Tool, that company could improve its keyword strategy with additional phrases like “baby clothes diy” and “baby clothes quilt,” both of which rank high as common search terms. You can also use the platform’s trend data to see what times of the year certain keywords perform best to change your strategy depending on consumer habits and holidays.

Keyword Tool

You can access Keyword Tool’s most basic features for free, but it has plenty of other features that are worth paying for, like cost-per-click data and competitor keyword analysis. Keyword Tool’s monthly plans range from $69 to $159 a month depending on the volume of keywords you plan to analyse.

Pros: • Simple interface with reliable keyword suggestions.
• We enjoyed its easy export options.
• Great for finding long-tail keywords.
Cons: • Free version has restricted data access.
• Limited advanced metrics.
Can get costly for premium features.

5. Keyword Keg

Keyword Keg

Keyword Keg is a 5 tool suite focused solely on keyword research, which collects data from 12 APIs in total. Where YouTube is concerned, Keyword Keg’s main use is as a tag generator.

All you need to do is pop your keyword(s) into the search bar and wait for the tool to populate a list of suggested keywords. You can then use these to help you decide which keywords to use in your titles, descriptions and tags.

Pretty standard so far, right? Well, there’s a neat little trick on offer – you can filter the results to only show keywords related to buyer intent, allowing you to shortlist keywords that are more likely to convert. Cha-ching!

Another handy bit of info can be found in the ‘Trend’ column – here you’re able to see whether a keyword is trending up or down based on search volume. Anything trending sharply downwards might not be worth your time.

Keyword Keg

Packages range from $38 per month for website owners and entrepreneurs to $762 per month for agencies, but you can save up to 40% on these prices with an annual package.

Pros: • Provides diverse data sources for keyword ideas.
• We appreciated the in-depth SERP analysis.
• Helpful for niche markets.
Cons: • Can be pricey for smaller businesses.
• Interface is not always THAT intuitive.

6. Keyword Tool Dominator

With a name like Keyword Tool Dominator, our expectations for this platform were high. While it isn’t quite as mind-blowing as its moniker would have you believe, it is a pretty easy-to-use tool for keyword research newbies.

Simply type a term into the search bar, and voila – Keyword Tool Dominator generates a lengthy list of the suggested YouTube search phrases that incorporate your term.

Keyword Tool Dominator

You can pick and choose which keywords you want to add to a custom list, and export your list all from the same screen. This tool keeps keyword research – and its pricing model – simple.

Keyword Tool Dominator is free for up to two searches per day. If you want to search more terms more frequently, you can get stuck in for a one-time price of $44. Keyword Tool Dominator also works with other major search engines, like Amazon, Etsy, eBay and more.

Pros: • Fast and accurate keyword suggestions across platforms.
• We found the platform really user-friendly.
• Great for multi-platform keyword research.
Cons: • Limited free searches available per day.
• Not as comprehensive as some competitors.
• Can lag with high volume searches.

7. Keywords Everywhere

Keywords Everywhere

Keywords Everywhere is a Chrome and Firefox extension that has a very specific set of features. Unlike the other tools on this list, it doesn’t focus on suggesting new phrases or tags. Instead, it’s all about cold hard data.

Search for a term on YouTube and you’ll immediately be shown monthly search volume, cost per click, competition level and trend data:

Keywords Everywhere

Another cool feature is the Search Insights Widget, which presents you with more handy data for each search you make. This sort of information should give you a good idea of what your video(s) will be up against in your chosen niche:

Keywords Everywhere

Keywords Everywhere is by no means the only keyword research tool you’ll need, but it’s a great addition to add to your arsenal. Some but not all of the data is free to access. Unlike the other tools we’ve covered so far, Keywords Everywhere uses a credits system – basically, you pay for a package ranging from $15 to $1000, each one coming with a certain amount of credits. You then spend these credits whenever you carry out a search (1 credit = 1 keyword).

Pros: • Integrates seamlessly with browsers for on-the-go research.
• We saved time with its instant metrics.
• Affordable credits system.
Cons: • Credits-based system can add up quickly with heavy use.
• Lacks advanced features.
• We struggled to find historical data analysis.

8. Sitechecker

Sitechecker is a keyword tag generator. Simply type in a word or phrase, and Sitechecker will generate a list of other high-performing tags that are related to your topic, search volume for those tags, and their cost per click. This tool is specifically great for international businesses; you can review keyword data and generate terms based on geography to modify your SEO strategy by country and by language.

Sitechecker is free for its basic features, but those won’t get you very far. If you decide to upgrade to a monthly membership, it’ll cost you from $41 per month for a Basic plan, up to $208 for a Premium account.

Pros: • Comprehensive website analysis and monitoring tools.
• Real-time updates.
Cons: • Some features require a premium subscription.
• Can be overwhelming for beginners.
• Occasional inaccuracies in reports.

9. HyperSuggest

HyperSuggest is a single keyword tool that works across nine different search channels, including YouTube, Amazon and eBay. Specifically, as it relates to YouTube, this tool is super easy to use.

Simply type in a search phrase and in seconds HyperSuggest pulls the top tags for YouTube videos related to that term, giving you a qualified list of search terms to include in your video title, description, tag list and transcript.

HyperSuggest also makes it easy to see what videos currently own the top spot for those terms; it links every phrase to its corresponding YouTube SERP. HyperSuggest gives you a basic list of results for free, but if you want to upgrade to see a complete list, you’ll need to pay for a Pro plan, which costs around $49 per month.

Pros: • Generates keywords from multiple platforms quickly.
• We found it a particularly speedy tool to use – good for quickly brainstorming content ideas.
Cons: • Limited in-depth analysis.
• Free version is quite restricted.

10. YouTube Autosuggest

Here’s a completely free tool hiding in plain sight! Ok, so perhaps not technically a tool, YouTube’s own autosuggest functionality is an under-the-radar option when it comes to keyword research. Simply head over to the search bar and start typing a keyword. You’ll then be presented with a host of suggestions containing that keyword.

For example, after typing “ab workout” we’re shown a number of useful ideas including “ab workout with dumbbells” and “ab workout for beginners”:

Crucially, these aren’t just random suggestions cooked up on the spot – they’re actually based on real search queries that people have previously searched for on YouTube.

Pros: • Provides real-time, trending keyword data directly from YouTube.
• No cost involved.
Cons: • Lacks advanced features found in dedicated tools.
• Data can be too broad.
• No export options.

11. Google Trends

Google Trends is another free resource worth checking out as part of your research. Enter your keyword, select your preferred date range and change the filter to “YouTube Search”. You’ll then have a good idea of whether that topic is becoming more or less popular over time.

You can also compare the relative popularity of two or more topics.

Pros: • Excellent for identifying trending topics and seasonal interest.
• We tracked market shifts effectively.
• Free and easy to use.
Cons: • Limited to relative popularity, not exact search volumes.
• Requires additional tools for deeper analysis.
• Not always specific enough for niche markets.

Our favourite YouTube keyword tool

Our #1 spot on this list goes to TubeBuddy. Why? We could go on and on, but here are the top four reasons we think this YouTube keyword tool rocks.

  1. It’s easy to use: TubeBuddy takes the most important information you need to do effective keyword research and populates it into a simple, sleek interface. It’s so uncomplicated even tech novices will feel comfortable using it.
  2. It’s comprehensive: TubeBuddy combines multiple functionalities into a single tool, meaning you won’t have to download several different programs to do all the research you need to do.
  3. It’s light-weight: TubeBuddy doesn’t require you to navigate a complicated, tiered subscription model or install yet another clunky piece of software onto your computer. This simple browser extension was designed to be straightforward and painless.
  4. It’s free: For most small and medium-sized businesses, paying for a tool that does something this specific isn’t in the budget, which is why we love TubeBuddy’s price tag: $0.
