What are Keyword Research Tools?

Keyword research tools are an essential part of SEO that is used to find the most relevant, profitable, search-oriented, traffic-driven, and sales targeted keywords that people search online.

As the name suggests these tools are used for keyword research, which is an SEO process used for revealing what exactly the majority of people type in search engines in order to find their desired results, and keyword research tools are used to perform this process.

If someone was looking for a criminal lawyer in Milwaukee they would probably type something like “Milwaukee Criminal Defense Lawyer” or “Milwaukee Criminal Defense Attorney” and many other variations of the same. Using keyword research tools we can find out the keywords people are typing into search engines to find a criminal lawyer in Milwaukee.

Some of you may still be confused about the use of keyword research tools or find it a bit expensive or even would be looking for more ways to find productive keywords.

We got some alternatives that would help you enhance your keyword research skills.

Here are keyword research alternatives:


Quora is a one of the worlds biggest Q&A website and you can find answers to almost every question.

You can also use Quora for keyword research, simply login and type in your keyword into the search box and hit enter.

You should now see all the questions, discussions and answers around your keyword, you can now pick the questions with the highest engagement and add a new version of it to your website.

This strategy has been quite effective, as you are creating fresh content on the topics your audience is discussing on the web, thus you are directly connecting with your audience.


The would number one social media platform, Facebook has a ton of data stored in it and all you need to do is explore it and you will be able to extract some quality keyword research data out of it.

One of the methods to use Facebook for keyword research is to simply type in your keyword or niche into the search box of Facebook and click groups.

Join the groups and look at the posts that have above average likes and comments.

You can also check general public posts outside of the groups however groups often offer the best keyword topics as compared to any other method.


Reddit is strong and powerful platform that have a sensible audience base, please don’t kill me for this, but yes, from my personal experience I have found Reddit to have the most sensible audience and you will find less amount of irrelevant content on it.

The trick to use Reddit as a keyword research tool is simple, pop your keyword into the search box and look at all the discussions around your topic, then copy all the relevant Reddit discussions and create something unique around that topic on your own website.

How do Keyword Research Tools Help with SEO?

Keyword research tools give us the monthly search volume of a particular keyword using which a business can plan their internet marketing strategy in a better way. It also provides us with a list of useful keywords that can be targetted for maximum profitability.

Over the years, while providing SEO services to my clients I have personally tried and tested almost every keyword research tool out there and was able to find a handful of them to be really helpful and in this article, I am going to not only name them but also explain why and how they are helpful.

Do Free Keyword Research Tools Work?

Yes, free keyword tools like UberSuggest definitely work however you cannot go deep with it and get a highly-optimized keyword data. It is perfect for small business with low competition however if you are in a highly competitive niche then you should definitely go for a paid tool such as Ahrefs for in-depth keyword research and analysis data.

Free tools for keyword research helps us get a quick report on the keyword ranking difficulty, keyword cost for paid ads as well as LSI keywords and supporting keywords that can be targeted for internal linking and growing web traffic.

What is the difference between Free and Paid Keyword Research Tools?

Both free and paid keyword tools are aimed to do the same thing however free tools provide limited data as compared to paid tools and this alone is the major difference between both of them.

The second difference that I found was that most of the free tools do not allow you to save your research within tool itself thus you have to download it or save it on your system whereas paid tools understand the importance of allowing clients to store data based on each project.

Lastly, free tools tend to provide less and old data which sometimes may hurt your SEO and paid tools tend to provide latest and up to date keyword report.

Importance of Keyword Research Tools

There you have it the top and best keyword research tools to help SEO professional, content writers, and webmasters achieve their target. Keywords are important and knowing which keyword to use on your pages and posts is the best practice to bring in better rankings and higher traffic to your website.

If you have a new website then use the tools mentioned above that focus on providing long-tail keywords with less competition first and they build your way to the medium and high competitive keywords.
