The 5 Best Free Keyword Research Tool  

Here are the four factors we have taken into consideration to select the 5 best free keyword research tools in 2024:  

Data  

Keyword Optimization Guidance  

Free Plan 

Unique Features  

The best keyword tool is the one that provides you with maximum and clear data you require for a specific keyword. So, all the keyword research tools we have selected provide keyword difficulty, SERP analysis, and much more.  

The top keyword research tools should not require you to be a 10-year SEO pro. Rather they should be very intuitive and simple to optimize for your keywords! 

This is essentially what we are seeking here. 

We have selected tools so simple that any business owner or marketer can effectively understand their focus keyword and optimize a page for ranking. 

Some tools have very restricted features in their free "plans" and call it all 'free'. 

Or they started adding time restriction on the free plan which meant essentially forcing all their users onto a trial. 

Because we only highlight tools with free access which are reliable and those that do not burn a hole in the pockets. 

As you are looking for a free solution, your keyword tool should have it all — so you do not need to install any additional tools or extensions, especially paid ones. 

 

Now let us talk about 5 best free keyword research tools in detail:  

Moz Keyword Tool

Pros  

Cons  

Pricing  

Approachable data presentation

Less data than other tools

Basic Plan - Free up to 10 queries per tool per month with up to 1000 keyword suggestions and 10 SERP analysis per query  

Pro Plan- Start at USD 99/month for 150 keyword queries per month

Clear prioritization metrics  

Free plan includes only 10 queries tool in a month

Multiple free tools and features  

 

Moz can be called an SEO stage; Moz contains numerous tools that are explicitly for keyword research. 

One thing we quite like about Moz is that it does not have as many data points as some of the other full-featured SEO tools. Yes, we count this as a benefit. Wondering why? 

Well, it means a cleaner user interface for those who are not professional search marketers with the number of metrics you actually care about still available. 

Google Keyword Planner  

Pros  

Cons  

Pricing  

Completely Free; even if you do not use Google Ads 

 

 

Not suitable for organic keyword research 

 

 

FREE 

Efficient forecasting features for budgeting 

Pull keyword suggestions from just your website  

Google Keyword Planner, as one of the most useful tools in PPC keyword research.  

According to a survey by Ahrefs in 2021, Google Ads Keyword Planner overestimates search volumes 54.28% of the time and is roughly accurate 45.22% of the time. 

It is free (works without buying Google Ads), so you do not have to worry about any limits or any costly upgrades. 

There are two main features within the Google Keyword Planner: one for exploring and discovering keywords, and another for more intricate research around search volume and forecasting. 

Like many other tools, the Keyword ideas feature allows you to enter a seed term and from that generates other keyword ideas with details like monthly search volume, change over time, competition level, ad impression share and bid ranges. 

If you have also got Google Ads running, its new "Forecast" tool can help you prepare paid ads and budget beforehand.

Semrush

Cons  

Pricing

Pro Plan- Start at USD 129.95/month for up to 10,000 results per report and 500 tracked keywords per month 

Multiple keyword research tools  

Extremely costly upgrade

Pocket-friendly FREE plan 

If you need something more sophisticated, Semrush will give you lots of keyword information (including plenty of long-tail and less competitive keywords) and segmentation that allows to get deeper insights with features like featured snippet, reviews, site links, image pack, etc. 

And these not only include standard traffic and search volume data, but also many of the more popular features that other web analysis tools offer such as content-driven keyword research and competitive keyword gap analysis. 

A just launched Copilot AI (Artificial Intelligence) in the app will now go as far as to suggest things like pointing out when your rankings have dropped for tracked keywords, suggesting technical SEO fixes, or asking if you would respond with additional information that may assist you better fine tune their data. 

This certainly means that the upgrade is going to be expensive, although you can use it for free at a very high volume.  

Free Keyword Research  

Pros  

Cons

100% FREE 

Unique suggestions for content angles  

No built-in way to save your research 

 

You should choose Ryan Robinson's Free Keyword Research Tool if you are seeking a simple tool to provide basic keyword data. 

The Explorer tab brings related queries for any keyword you search, along with (ballpark) search volume numbers and a keyword difficulty designation from “low” to “very high.” 

The feature we are most impressed with is the suggested angles for content. 

You must also use the Ideas tab (or click on the lightbulb icon next to any of the related keywords) and you will see long-form suggestions which can shape your angle in content production. 

But you know what, as many times we used their free tool, we got a lot of data which unfortunately is not enough—and also there is no upgrade option anytime when you can afford to invest in your search strategy. 

But if you simply need basic keyword research, this tool may be worth a look. 

Ahrefs Webmaster Tools  

Pros  

Cons  

Pricing  

Advanced keyword explorer 

Involves a learning curve 

Basic Plan – Free (Limited) 

 

Pro Plan- USD 83 per month (billed annually)

If combined, all of these features can enable you to better construct and execute an intelligent search strategy. 

Plus, Ahrefs allows businesses to make better-informed SEO-related decisions by helping them determine which pieces of content are more likely to rank quickly or dominate over their competition, which gives them the ability to use other marketing resources and their team's time more efficiently.
