Keyword Research Tools – Free & Paid

One of the most crucial and pivotal part of SEO is keyword. The primary foundation of SEO is keyword research. In addition to keyword research, there are other factors such as Writing SEO friendly content, a good UX and drafting content which satiates the user intent. There are a few other factors, along with the ones already mentioned, that are crucial in performing SEO.

All the keywords that you wish to focus on for the right search engine optimization (SEO) efforts are extremely important for the success and the ranking of your website.

It is not always intuitive or easy for you to pick the right keyword. You will not only need a lot of research but also a lot of data to decide whether the given keyword is right for you or not.

Now, when you have the adequate knowledge of the basics of keyword research and know how valuable it can be, it is time to delve deeper and get a better understanding on the subject.

At present, there are mainly two types of Keyword research tool available. These include:

  • Basic Keyword research – The Basic Keyword research can be used by you to seed the keywords so as to dig in the most profitable ones.
  • Competitor based Keyword research – Under the Competitor based Keyword research, you can find the proven keywords which are actually helping other sites to pull out more traffic.

Honestly, in my personal opinion, I like the Competitor based Keyword research a little more effective than the Basic Keyword research tool since the function of the Keyword research is to dig in some profitable keywords. And there just couldn’t be anything more profitable than something that is already working great for someone.

So, basically, all that you have to do is create a page which targets profitable keyword and reap in great benefits of your keyword research.

However, in the exclusive guide provided here, we have included both the type of keywords. Please note that almost all type of these keyword research tools are paid. However, there are some mentioned here, which are free too.


When you think of those typical keyword research tools, you limit your thoughts. However, SEMRUSH does a lot more than just researching keywords. You know, what happens with most of the keyword research tools? You’ll have to add seed keywords before you can start your research. On the other hand, with SEMRUSH, you can just add your URL or the URL of your competitor and on the basis of it, you’ll see all the keywords which are ranking for the site. Based on this, it is really simple for you to find both the short tail as well as the long tail keywords which you can target and thereafter, beat your competition.

With this, you can get in depth details on:

  • Traffic stats
  • Search engine reports
  • Website Analysis
  • AdSenseCPC
  • Backlink Analysis

In addition to these, you can get other details which are needed by you to properly manage your SEO campaign.

Ahrefs Keyword Explorer Tool

If we judge by popularity, Ahrefs is definitely one of the most popular keyword research tools available out there. Honestly, what I really like and appreciate about Ahrefs is its extensive detail including the keyword difficulty. With Ahrefs, you can even see how many clicks you’ll get with the search engine.

This is undoubtedly, a very useful tool after knowledge graph integration. You must have experienced, that there may be some keywords which have massive traffic yet despite that they do not get any clicks on the search engine.

You know what’s the reason behind it is? The reason is, that they get answers directly from the Google search result.

For instance, one such query is the “date of any festival.”

This is not it. There is more to what Ahrefs Keyword research tool offers. This tools, has a great User Interface and the amount of data it offers is unmatchable. So, when you have Ahrefs, you don’t have to use excel. And this is an amazingly time saving feature of Ahrefs.

Google Keyword Planner 

When we talk about the keyword research tools, the first name that comes in mind for most people is the Google Keyword Planner tool. This is definitely the most popular and undoubtedly the most used keyword research tool out there.

The primary reason for the popularity of the Google Keyword Planner tool is that it is 100% free for use. Moreover, it is integrated with Google AdWords and this adds on to its popularity. Further, this is very easy to use.

Now, before you begin using this tool, you need to have a Google AdWords account. In case you still don’t have one, just click hereand you can begin creating your account.

Let’s understand the Google Keyword Planner tool a little more.


The best feature of the Google Keyword Planner tool is that it offers deep information on the Google, which you all know, is the largest available search engine.


Of course, the feature mentioned above, can sometimes, even act as a limitation. Moreover, if you wish to know how your site or even a given keyword, is going to perform on other search engines, that’s something Google Keyword Planner tool won’t help you with. So, this definitely is a big limitation of the Google Keyword Planner tool.


As for the pricing of the Google Keyword Planner tool is concerned, it is absolutely free to use

On the whole, if your website’s SEO is on its initial stages, the Google Keyword Planner tool can be a great tool to use.

Sometime ago, this used to be my favourite free tool however, the fact that it is limited and does not provide the exact data is disappointing. So, if you need a detailed and a competitive analysis, I would recommend you to opt for the other advanced tools that I have listed below.
