Best Keyword Research Tools (Paid and Free) Updated

Best Keyword Research Tools (Paid and Free) Updated

A digital marketeer without relevant tools is like a soldier without weapons. No matter how skillful the soldier is, there is no chance he can overcome his enemy, who is equipped with heavy ammunition. 

Similarly, you cannot rank a website/blog without a good keyword research tool. 

Luckily there are more than a dozen tools available in the market, both paid and free. While this is a good thing as it gives you a variety to choose from, it might confuse some people, especially beginners.

Therefore, I have created a comprehensive guide of the best keyword research tools in the market. The list includes both paid and free tools so that you can choose according to your budget. 

So let’s dive straight in

Free Keyword Research Tool

Keyword research doesn’t always have to be a costly endeavor. That is why we begin our guide with a list of free tools.

Free doesn’t mean they are substandard. Just read out the features of the tools as you will go by me that they are worth using. 

So let’s get started


Many free keyword research tools are limited to one channel. As such, if you want to do research for multiple channels, e.g., Google, Bing, YouTube, etc., you either require going for a paid tool or have to access multiple free keyword research tools. 

With Soovle, that is not the case at all. It allows you to search for multiple platforms, including eBay and Amazon.

Soovle provides data such as search volume, competition (whether it is high or low), and Cost Per Click (among other useful metrics)

Apart from finding the difficulty of a keyword, you can also use Soovle to brainstorm different keywords. For that, you should enter your seed or root keyword, and Soovle will provide you with the related keywords.


  • Keyword research from multiple channels at a time, e.g., Amazon, Youtube, Bing, Wikipedia etc
  • No limit to the number of searches you can make


  • You can only find keyword suggestions and no search volume, keyword difficulty and other important metrics
  • Poor layout of the website might put off some people

Google Keyword Planner

Note: You need to have an AdWords account in order to access Google Keyword Planner. That is why the hyperlink leads to page.

No list of keyword research tools will be complete without the mention of Google. 

Google Keyword Planner provides you with average monthly searches, Cost Per Click (CPC), and competition level of the keyword. All these metrics are important for effective keyword research.   

But you can find these stats in every other keyword research tool. What sets Google Keyword Planner apart is the keyword synonyms and variations it provides. 

Also, note that you can also get data on CPC, which means in case you need to rank your keywords using paid method i.e., Search Engine Marketing (SEM), the data will be a good guide.


  • Unlike almost all other keyword research tools, Google Keyword Planner can show you the data for the past four years. Impressive, isn’t it?
  • Data is almost 100% accurate as Google pulls it from its own search engine.


  • Keyword filters have been reduced, which makes it difficult to search data for exact match keywords
  • You can only search for three keywords at a time, which is very limited.

Here comes another free tool by Google. It differentiates from others as Google Trends doesn’t show you the keyword difficulty, search volume or the usual metrics of keyword research tools.  

 Rather, it allows you to see which of the keywords are trending via a graph. The best part is that you can do a couple of searches simultaneously and be able to extract out a relative value of different keywords. 

You may search for your targeted keyword in different geographical locations and at different times. For example, you are searching for ‘Home Maker’ in the USA and the UK region for the past 12 months.

This will show you the graph for “Home Maker” in both regions, and you will be able to make a comparison. 

Another encouraging feature is the fact that you can carry out the search for a wide variety of platforms. Google Trends gives you the option to make an image search, youtube search, news search, google shopping, or a web search. 

This option will truly be handy for those aiming to carry out keyword research for multiple platforms, rather than just Google.

Google Trends lets one have a thorough insight into the audience needs, to its exact. It does not just help you get through with the keyword research, but it guides you to a subtle market strategy that enables you to win over more clients than before. 


  • User friendly, easy to use interface. You just have to make a few clicks to use it.
  • The best part of this is, it uses graphs to compare search queries over different times to make analysis much more effortless. 


  • The graphs are mainly not available for long-tail keywords. 
  • Google Trends is not as specific in its searches. There isn’t an absolute graphical representation for your searches. Rather it depends on relative values. 

Answer The Public

Right keywords can legitimately win potential customers. Answer the Public is an insight keyword tool that helps you optimize your content in the right direction. It offers a combination of searches from Bing and Google in a search cloud. 

Answer the Public offers Google suggested search options as a SEARCH CLOUD or in a cluster. This lets you discover what your target audience is searching for. Answer the Public is the right tool to search for ideas for your blog posts or even for podcasts.

This tool is different from others as it presents the questions related to your typed keywords in a carousel ring. These questions are who, when, where, how, and a lot more interrogative words. 

For example, you type in Coffee. Answer the Public shows various questions such as “Where coffee is grown,” “How coffee affects the brain,” “What coffee machine to buy,” etc

Additionally, there is also the option of adding a preposition to your keyword as well as comparison phrases such as verses, like, etc.

For Coffee, you can see prepositions such as “coffee with,” “Coffee is,” “Coffee can,” etc. Similarly, you will see comparison phrases such as “Coffee versus,” “Coffee like,” etc. 

Answer the Public, lets you know your audience, target the mainstream keywords, optimize long-tail keywords, and increases the chances of being featured on Google snippets. 

Snippets are the short answers that appear on Google in response to the questions that you type in. 

In short, Answer the Public extracts useful phrases people search for and lets you have a detailed insight into various topics.  


  • Presentation of data is easy in two forms; visual format and straight data. 
  • Several suggestions are just there on a single click. 


  • Search Volume is not displayed; hence, an alternate keyword tool is required. 
  • It only helps you generate keyword ideas, therefore not a tool to extract keywords you’re supposed to rank on. 

Paid Keyword Research Tools

If you are an advanced blogger or your site has started to get traffic, and now you want to take it to the next height, a free keyword research tool won’t do the job.

That is why we share a few paid tools that are well known in the market. 

So let’s dig into them


Ahref is one of the most popular keyword research tools in the market. In fact, there are a few things that only Ahref can do

It has all the things that you will need for keyword research. For example, you can check the usual keyword difficulty and search volume. Ahref also provides keyword suggestions based on the seed keyword you enter.

Additionally, you can also analyze the entire website of your competitor. This includes finding out what keywords they are ranking on, the overall traffic, and backlinks to the site, among other things.

In short, Ahref is your all in one tool for keyword research and competitor analysis. 


  • Ahref provides detailed keyword research as well as competitor analysis
  • Free backlink checker


  • Price is a bit higher compared to many other tools
  • Traffic stats are not very accurate

Long Tail Pro

As the name suggests, Long Tail Pro helps you generate long-tail keywords. In case you are not aware, a long tail keyword ranks in no time and, as such, is preferred by bloggers over short-tail keywords.  

The software generates over 400 keyword suggestions from a seed keyword in a couple of seconds. You can use these keywords for all types of sites: affiliate, Adsense based etc.

Apart from keyword research, you can also use Long Tail Pro to analyze your competitors’ keyword strategy and dissect it.

The thing I love the most about Long Tail Pro is the option to save and group keywords. In this way, you don’t have to copy-paste the keywords into a separate document. Isn’t this interesting?


  • You can get over 400 words from a single seed keyword
  • In one go, you can check the ranking on Bing, Google, and Yahoo


  • Speed is a bit slow
  • Shows limited results for the competitors


SEMRush comes in three different packages, so you can choose from the one best suited for your needs. There is also a seven days trial you can avail if you are not sure if SEMRush can fulfill your requirements. 

The tool allows you to deeply analyze the competitor’s keyword strategy by seeing what are the top keywords they rank for as well as the search volume and CPC. 

Just like Ahref, SEMTRush has it’s own ranking metric called “SEMRush Rank” data. This is the ranking of the site based on SEMRush’s extensive database.

Apart from the competitor analysis, you can also perform keyword research. For that, you have to follow the same procedure that you do for other tools I.e., enter a seed keyword, and SEMRush will show the long-tail variation of it. 

Even better, SEMRush will show you related keywords, which are again long tail and can help you generate good content. 

Keyword research and competitor analysis are just two of the thing the tool does. Apart from this, you can do a site audit, backlink analysis, and link building as well. 

In short, SEMRush allows an individual to perform a wide range of things and might be a good option for anyone looking for all in one tool. 


  • There is a site audit option that analyzes every issue on your website. This is rare to find
  • Extremely good interface with lots of charts and graphs that are easy to understand


  • SEMRush only provides data from Google
  • Using a free trail requires you to enter a credit card, which might scare a lot of people 


Keywords always form the basis for SEO only if you’re going right. Moz is a potential SEO tool that not only allows you to do SEO of your website but also helps you diagnose crucial issues your site owns. To discover this, you need to have pro access to the site

Once you’re a premium member and have logged in after agreeing to their terms, you may have access to numerous keywords via the KEYWORD EXPLORER. Now, you may enter the exact keyword or may have a search for keywords as well. But, make sure you’re searching in the right country. 

Moz helps you get to the metrics that help you analyze keywords’ monthly volume, landing difficulty on the first page, organic click-through rate, and the Moz score. Moz score enables you to prioritize what comes first and what next.  

It, too, helps you evaluate while going through SERP analysis. Additionally, it allows you to broaden your horizon by suggesting a wide variety of keywords to pin-down the stuff on your priority. 

Moz also allows you to dive into the suggestion page that helps you get the comprehensive keyword database, which you can filter according to your need. 

Not just this, it helps you to do Link Analysis via the LINK RESEARCH TOOL/LINK EXPLORER.


  • 95% accuracy is attainable with Moz’s search volume metrics making it the most reliable keyword research tool in the market. 
  • Moz Potential Metric allows you to narrow down your search list to target the most relevant keywords very first. 
  • Help you analyze your competitor’s websites and their keywords side by side. 
  • Moz’s dashboards are just right for keyword searching, planning, and web analysis.


  • Moz’s crawls are not very ideal for complicated websites.  
  • The custom reports option is not handy to be used. 
  • Keyword tracking restrictions exist with Moz. 


This was all about the top free and paid keyword research tools in the market. As you have read, each tool has its own pros and cons, and as such, you carefully need to make a choice.

To do so, closely examine your needs. For example, how many keywords you will need to research on a daily basis, whether you need to do keyword research only for Google or other sites as well? 

And a lot more questions!

After you have asked yourself all these questions, select the tool which best answers them. In this way, you won’t regret your decision.

So which tool have you decided to purchase? Let me know in the comments below. I am eager to hear from you.

How to use Ahref to find low competition keywords?

How to use Ahref to find low competition keywords?

Finding low competition keywords is the foundation of Search Engine Optimization (SEO). After all, the epic content you have written would be hardly of any use if it doesn’t rank on the first page. 

If you search “how to do keyword research”, you will literally come across dozens of articles written on the topic and hundreds of YouTube videos.  That makes it harder to digest information, especially if you are new to SEO. 

Realizing this problem, we decided to create a comprehensive guide on keyword research using Ahref. 

We will begin by talking about what exactly is keyword research, and it’s importance in SEO. Next, we will mention why Ahref should be your go-to tool for keyword research and finally, how to actually carry out the research. 

Sounds interesting? Let’s get started.  

What is keyword research (KR)?

At its core, KR is the process of finding those words (also called keywords) which have low competition but good traffic on a search engine. 

Low competition means they can easily be ranked among the top 10 results of a search engine. 

You can then use these keywords in your article or your website, which will help you rank above your competitor. 

If your KR is good, as well as the content, you may even land on the top spot of Google. Imagine how much traffic you could get and the resultant growth of your business if you manage to grab the top spot. 

That is why we said earlier that KR is the foundation of SEO.

Why use Ahref for keyword research?

If you are to summarize the definition of keyword research (KR) in a sentence, it is to reverse engineer your competitor. 

To do so, there are dozens of tools available in the market. Ahref is one of the best as it provides very detailed information about the competitor. It is literally like you are spying on your competitor. Of course legally.

Ahref also ranks among the top KR tools in the market. Therefore, we selected it to explain the KR process. In fact, there are 13 things that only Ahref can do for you.

How to use Ahref?

Here comes the main part of the article, I.e. how to actually use Ahref to find low competition keywords. The process is much simpler than you might be thinking of, thanks to the user-friendly interface of Ahref.

Step 1: Find seed keywords or the competitors site

A seed keyword is that word which you will type into Ahref to kickstart your keyword research (KR) process. 

You might be wondering what seed keyword can I type into Ahref. Well, that depends on your business. 

If you sell mobile phones, seed keywords could possibly be mobile phones, mobile cover, name of a particular mobile phone, etc. 

You need to enter the seed keyword in the “keyword explorer” section of Ahref. It will show you the difficulty as well as other related keywords.

Scrolling down will show the related keywords

Another simpler way is to copy-paste the URL of your competitor and analyze the keywords. For this, you need to click on “dashboard” which will lead you to a homepage where you can insert the link.

Step 2: Filter the keywords

You will be getting thousands of keywords via the above method. Therefore, it is pertinent to filter them down and select the most relevant ones. 

Let me demonstrate how to do so. 

Continuing the above example, let’s assume you want to start a blog where you inform the public about different things related to mobile phones. 

This could be information on various mobile brands you sell, the latest phone released in the market, or troubleshooting guidelines. 

So you type in “mobile phone blog” in the search engine and insert the link of any competitor in Ahref. Here is what you will see.

On the left-hand sidebar, you need to click on “Organic keywords” which will lead you to another page showing the keywords the competitor is ranking for. Additionally, you can also find other useful metrics such as volume (which is the search volume), keyword difficulty (KD), and the position of the keyword in the search engine.

This is where the real game begins. You need to see which of the keywords are related to your business and have low competition. 

Now the low competition is a subjective term. For some people, a low keyword difficulty (KD) can be anything between 0-10, while others might even go beyond.

Step 3: Analyze the content that ranks for these keywords

As we mentioned above, the URL section will tell you what content has been written for each keyword. 

This analysis of content is important as it will help you figure out the loopholes of the competitor which you can cover. Resultantly, you will succeed in providing more value to the reader and have better chances of ranking above your competition. 

Keyword research is a never-ending process. Using the above three steps will allow you to extract low competition keywords. However, you need to remember that this practice needs to be repeated again and again. 

The reason being, you need to constantly release content in order to stay in the limelight. People want to be informed about the latest happenings, and that would not be possible if you are publishing just one blog post per week.

Keyword research is the first step

What use would be the keyword if it isn’t converted into words? Therefore, make sure you don’t stop at keyword research but work on converting them into highly informative content that readers will love.
