The Top 7 Free Keyword Research Tools

Keyword tools are expensive—you need to shell out at least $40 per month to be able to use these services.

The thing is, these tools are best used by giant companies competing for the top spot.

If you are a blogger or an e-commerce entrepreneur, you would be hard pressed to purchase these tools. 

But this is not the end. Today, I will show you seven free keyword research tools that you can use to plan your articles and content. 

These tools are: 

  • Answer the Public
  • LSI Graph
  • UberSuggest
  • Google Alphabet Soup
  • Google Trends
  • Google Keyword Planner
  • Keywordtool.IO

Since these keyword tools are free, there are limitations as to what you can do.

As always, there is an option to upgrade if you want to get better results or if you want more juice out of the tool.


The Top 7 Free Keyword Research Tools

Let us now discus the top free keyword research tools that I highly recommend.

1. Answer the Public

Answer the Public is a tool where you can type a keyword and it will generate questions.

In the free version, it does not really tell you the search volume, but it does tell you what kind of questions people are asking and searching for. 

Here is a screenshot of how it looks like:

Answer-the-Public

Answer the Public is great for writing response posts.

Response posts are articles that aim to answer a question.

The keywords you see are questions asked on search engines, which means that they are looking for answers for their problems.

This is why it is called Answer the Public. It tells you what people are asking, and then it is up to you to provide and answer. 

Answer the Public has a paid version that costs $99 per month.

In this plan, you get a myriad of tools and features that are not available in the free version.

Examples of these features are: 

  • No limits on searches
  • No limits on users
  • A chart where you can compare data over time
  • Export the keywords to a spreadsheet
  • Priority customer support

As a niche site owner, you should not upgrade to the PRO version unless you have reached a phase where your sales can pay for the monthly cost of this tool.

Stick to the free version and create articles based on the search results.  

2. LSI Graph

In SEO, there is such a thing called LSI, which stands for Latent Semantic Indexing.

This refers to words that are not exactly keywords, but are related to the main keyword of the article. 

For example, the term PS can mean Photoshop or PlayStation.

The way Google will determine what your article is about is through LSI.

If you use words or phrases like “games” and “controller”, Google will know that the keyword you used is about PlayStation, not Photoshop. 

The words “games” and “controller” are called LSI keywords.

They support your main keyword, and they can sometimes act as the keywords that the user is searching for. 

Here is a screenshot of LSI Graph:

LSI-Graph

It is up to you to choose on the left-hand side what LSI keywords you want to use.

Naturally, you want to use those that have a high search volume.

You can use the blue bar charts as your guide. These bar charts represent search volume over time.

On the ride side of the panel, you will see the top performing content for the keyword that you used.

You can open these links and analyze what the content is about, and then you can write something better. 

3. UberSuggest

UberSuggest is a free keyword tool from Neil Patel. Over time, the tool is going to require you to log-in with your Google account. 

The tool not only provides search volumes, but also recommended keywords plus the possible cost of each click if you ever think of using the keyword for an ad.

Here is a sample keyword search on UberSuggest for Playstation 5. 

UberSuggest

As you can see, the tool tells you that the search volume for PlayStation 5 is at 450,000 per month, which means that a lot of people are interested in the product.

The SEO difficulty is 70, and this should tell you that it is difficult to rank for this keyword. 

The KW difficulty is set between 0 and 100. A score of 100 means it is a tough keyword to rank for.

The same goes with paid difficulty.

It just means that you are going to have to pay more on your advertising bids so Google will show your ad to more people. 

If you explore this tool, it has an area called keyword ideas.

In this section, you will get a lot of other keywords related to the first one you searched for, along with volume, CPC, and others.

You will also have access to content ideas—a list of articles that people already wrote and published, all of which are ranking high on search engines.

4. Google Alphabet Soup

If there is one reliable source of keywords, it is Google.

Since Google is the biggest search engine of all, it has a record of all searches made on its platform. 

If you type words on the Google search engine, it does an auto-complete.

Even if you are not yet done typing, you will see topics suggestions below the search bar. 

What does this mean? To begin with, the Google search engine is not going to suggest these keywords if nobody is searching for them.

At first, people thought that it was just an auto-spelling, but it is now known that it is not an auto-spell but an auto-suggest feature.

Take a look at this:

what-is-dropshipping

There are so many possible words that start with the word “drop”, but drop shipping is at the top.

If you are the writer, then you know that there are people who are using the long-tail keyword “what is dropshipping”.

You can use this to your advantage and write an article about it.

Or you can use the alphabet soup as shown below. 

best-dropshipping-apps

If you type “best dropshipping a”, Google will show topics that start with the letter A such as apps, ads, agents, etc. 

If you type “best dropshipping c”, Google will suggest topics that start with the letter C such as courses and companies.

Remember: these long-tail keywords are things that people are searching for.

You have a guaranteed audience—people who are using these search phrases because they need information, and you can create content for them.   

5. Google Trends

Google Trends is another Google keyword traffic tool.

With this, you will see how keywords and terms are fluctuating in search volume over a period of time. 

Here is an example:

Google-Trends

For the long-tail keyword “what is dropshipping”, it shows that the trend is erratic, but there are searches for it.

The term you search for is rated between 0 and 100, with 100 meaning that there is a lot of interest about the term.

You can use this a guide and find out if a lot of users are using this term on the Google search engine. 

It is up to you to narrow down your search. You can toggle your search demographics with the dropdowns.

You can search by country, by time, by category, and by platform. 

The web search area is a dropdown, and you can tell the software to search only for trends in Google news, the search engine, or only in YouTube.

This tool is one of the most helpful and reliable keyword tools out there because it is owned by Google.

Naturally, the results you see here are not guesses, but real data from Google itself. 

6. Google Keyword Planner

The Google Keyword Planner is a tool that advertisers use.

It allows them to see how much they would have to bid for a keyword if they plan to advertise, and which keywords have a high competition.

You need a Google Ads account before you can use this too. 

Signing up for an account is free, and it is easy to learn how to use Google keyword planner.

Take a look at this: 

Google-Keyword-Planner

As you can see, I used the keyword “what is dropshipping” and Google is now showing me several variations or related terms with it.

The Competition column is what tells me whether this keyword is sought after by many advertisers or now.

What you want is a Low and Medium score if you want to write about stuff that nobody is advertising for.

For High competition, it means that a lot of advertisers are paying for it. 

And if advertisers are paying for it, it means that there is a massive search volume for the keyword.

It is your choice whether you want to attack low-competition or high-competition keywords.

What’s important is that that you also look at the Average Monthly Searches column. 

This column tells you the range of search for a keyword from a particular location and the month that you searched for.

Use this number as a guide to determine if there is a volume for your chosen keyword. 

7. Keywordtool.IO

This tool is helpful if you want to narrow down your search on specific platforms.

As you can see on the screen shot below, you can choose how the tool will give you results.

If you only want results from Amazon, eBay, or social media, this tool can help you with that. 

Keywordtool.IO

You can also choose which country to search for.

This will help you plan your keyword in a really precise and targeted manner.

This tool uses the Google auto-complete function, but it does a good job of segregating search results based on country and platform. 

free-keyword-spy-tool

It is like a free keyword spy tool because you will know what people are looking for on a specific platform.

In the example above, you will see that on Google, the keyword “dropship” yielded “dropshipping” as a term with a million search volume.

The trend is positive at +123%, and the competition is only medium.

If you continue scrolling down, you will also see more keywords related to your original search term.

With a free account, some of the results are hidden and you need to subscribe to a paid version if you want to see them. 

The paid version is not so important unless you are a big-time corporation, like if you are a news channel or a marketing agency driving traffic to a client.

If you are operating a small business, the results of the free tool will work just fine.  


Summary

While keywords are important, the focus of every article you write should be the user.

Google has long recognized the problem with keywords such as stuffing and publishing useless content with lots of backlinks.

Over time, Google introduced new algorithms that can detect if an article is useless.

Despite using all the keywords that you can, Google is not going to rank your blog page if it does not add value to the user. 

Google knows if your content is valuable, so make sure that you publish useful content.

Use keywords as a guide, but not as a means to game the search engine system.
