You can click on any of the results and you will be taken to the SERP of that term. There you can see which pages are ranking there. 

Their free version is well enough for bloggers and learners. But if you’re willing to perform research more often, you would need their pro plan. 

Keyword Sheeter

Keyword Sheeter approaches the research somewhat similar to AnswerThePublic. It too draws the autocomplete results from search engines and delivers them to you. The better thing is, it works on real-time data, so it could be more reliable. 

Also, it is a better option for those who want to make a long list of keyword ideas quick. As Keyword Sheeter on average delivers 1,000 keyword ideas per minute.

QuestionDB delivers you the questions based on the term that you enter. It pulls them from Reddit threads. 

It can be looked at as an alternative to AnswerThePublic specifically for finding questions. 

One of the best features is popularity.

Freemium Keyword Research Tools For SEO

Some of the websites offer paid tools to use for free for a limited time. The best thing is, you get the same amazing service as the premium plan. The only catch is you get to use it for a limited count of searches. But still, they are good enough to use as one of the best free SEO keyword research tools. 


Get smarter information. 

It hasn’t been a long time since Ahrefs have released their “Keyword Explorer“.

The best thing they offer is smarter or say more in-depth information on every keyword. 

It includes obvious information like volume and all. In addition, it gives you a breakdown of the competition between pages on the first page. Plus, how many users actually tap and read a result on a specific keyword’s SERP. 

Is that all? Nope. 

Here comes another fascinating feature, Keyword Difficulty. 

Yeah I know, it’s not something new but they got an out-of-the-box enhancement to the feature. Usually, keyword analysis tools give you the difficulty score as “easy” or “very hard” and others give scores like “55/100”.

But Ahrefs came up with an innovative idea. It gives you the exact number of backlinks you’ll require to rank on the first SERP. 

Generally, Ahrefs is well known for its amazing backlink analysis feature. But their Keyword explorer surely came out as a fascinating keyword research tool for SEO. 

SEMrush Keyword Magic Tool

The SEO juggernaut SEMrush offers its keyword magic tool as one of the various free tools it offers for SEO. To start using it, you’ll have to create an account and select the Skip Trial option. 

SEMrush’s Keyword Magic Tool have an immense database of 20 billion keywords ranging from 120 different geographics. 

Their free plan offerings are:

  • Search volume based on a monthly basis

The renowned name in the SEO world Neil Patel offers his own keyword research tool, Ubersuggest. It’s one of the most used SEO keyword research tools out there. Its offerings include search volume, related keyword suggestions, keyword difficulty for ranking and more.

Catering the traffic attracting keywords. 

Moz’s Keyword Explorer just like other tools have the feature of suggesting related or “lateral” keyword ideas. But the thing that makes it better is, it’s Smart. Or you can say Too Smart. 

General keyword research tools suggest related keywords that include the word of seed keyword. But Moz does it better as it does not focus on the word rather its meaning. 

It doesn’t limit to that, it gets more fascinating features that you won’t find anywhere else. They are “Organic CTR” and “Priority”.

Organic CTR: It is the estimated clicks to expect if you get ranked in the top 10 results. It works like, if a result page has too many PPC ads, the organic CTR value will be lower than the pages that do not have PPC ads. 

Priority: It mixes up the CTR, difficulty and search volume of a keyword to give you a score. That way you can see if you should target that keyword or not. 

Moz is undoubtedly one of the best SEO keyword research tools out there. But the catch is that you can access only 10 queries per month with the free account. 

There are several exclusive features in Moz’s keyword analysis tool. If you want to read more about its free and premium features, you can refer to MozBar Extension

Keyword Analysis Tools For Online Sellers, E-commerce And Multichannel Marketers

Generally, you’ll see most of the free SEO keyword research tools focus on search engines like Google, Bing and YouTube. But there are other platforms too like Amazon and eBay that are important to the e-commerce sector. And they have their own algorithms hence, their own data of keywords. 

Not to worry, there are keyword analysis tools that help you draw information about keywords for e-commerce platforms. That way, you can use better terms for your product and get more impressions and ultimately more purchases. 


Soovle brings you related or suggested keywords from various sources like Google, Amazon, YouTube, eBay, Bing and others too. 

It helps you get your hands on the keywords that your competitor most probably don’t know about. 

You can also save your favourite suggested keywords in one place and then download the list in a .csv file. 

Soovle does not limit the number of searches even on a free account. But the catch here is that it does not provide additional information like search volume or keyword difficulty. 

Keyword Tool Dominator

Keyword Tool Dominator tool lets you see the trends as they begin. Its speed and up-to-date database are what makes it special. It draws out autocomplete suggestions from platforms like Google, YouTube, Amazon, Walmart, Etsy and others.
