The main benefit of using this tool is easy to understand: you can extract information directly from Google, the search engine you are most likely to target when optimising your site for it.

Of course, being a Google product helps build an important user base. What marketers really appreciate is the large number of long-tail keyword suggestions you can get: 100% free and that quite impressive.

There are two ways to use the Keyword Planner: search for new keyword opportunities, see the search volume, and other metrics for your current keywords for our post.

To use Keyword Planner to search for keywords, select “Search for new keywords.” Next, you will be asked to enter basic keywords or the URL of a relevant page.

The Keyword Planner is expected to have hundreds of keyword ideas on hand, including key metrics such as average monthly searches, competitive quotes, and average CPC bids.

Final Remarks on Google Keyword Planner | What We Like Most?

Google Keyword Planner really offers you more than just the opportunity to provide many keyword ideas for SEO (Search Engine Optimization). The ability of the tool to automatically group similar keywords ideas and that’s really interesting.

If you are looking for a keyword research tool with the most advanced filtering capability, the Google  Keyword Planner should be your first choice.  Even you can just filter the keywords by competitiveness, search traffic, organic impression exchange, etc.

The Keyword Planner is also one of the few tools to simply eliminate “adult keywords” immediately.

All of the features of the Google Keyword Planner tools makes it’s the best free option available out there in the market.

2. AnswerThePublic

If you want to do keyword research for your post and content, I recommend AnswerThePublic. Actually, it’s a  keyword research tool that consolidates Google’s and Bing’s “autocomplete” data to display the most reliable results.

Unlike the  Ubersuggest, it is not necessary to create an account with AnswerThePublic to perform a keyword search. Simply insert seed keywords or phrase and click “Ask questions” to begin the search.


The AnswerThePublic engine generates search clouds with long-tail keyword ideas as well.

To understand what I’m talking about, let’s simply go to the search query “questions”, which is located at the top of the results page: and type in the keyword blogging.

Answerthepublic 01
Answerthepublic 01

Basically, a search cloud is a ideas map of long-tail keywords that contain specific terms, such as “WH”, question words, prepositions, and other conjunctions.

In the previous example, you can see that your target keyword is preceded by question words: who, why, where, when, who, who, what, what, what and how. These reflect the queries that users search on Google or Bing that is what make this tool one of the best free SEO tools on the market.

If you have trouble finding keywords with the Search Cloud visualisations, go to the Data tab also.

Final Remarks on AnswerThePublic  | What We Like Most?

AnswerThePublic fills the context with long keywords and gives you a clear idea of ​​the user’s intention. And better data insights. However, there are usually fewer suggestions than other search tools in the market.

I will recommend AnswerThePublic bloggers who need ideas on topics but don’t totally rely on it.

It is true that you can download keywords as a CSV file with a single click, but there is absolutely no metric that can be found in the tool. As a suggestion, you should always use AnswerThePublic with another keyword research tool to retrieve metrics for your keyword because the search volume, keyword difficulty, and many others parameter are worth looking at.

3. Ubersuggest

Ubersuggest is one of my favorite keyword search tools and I think after using it once you will be going to love it.

While loading the Ubersuggest page, you can start searching for keywords immediately. Simply enter a domain URL or start a keyword, set preferences for your region and click on Search. And bravo! You get the best keywords for free.


As we want to explore the search capabilities of Ubersuggest, let’s say you entered the keyword “blogging” here.

After a few seconds, the tool should present an introduction page right with important statistics, such as the average monthly keyword search volume, the  , the cost per click or the CPC and more.

Ubersuggest 01
Ubersuggest 01

For long tail keyword suggestions, simply menu on the left and click on Keyword Ideas. This should give you a long list of suggestions for keywords and from where you are going to get a list of best long tails keywords.

In my experience, Ubersuggest can easily generate hundreds of useful long-term keyword suggestions without putting many efforts.

It will also display the first 99 pages of the search engine or the SERP page of your original keyword and your estimated traffic as well and that quite impressive.

The most difficult aspect of keyword research is finding keywords that meet your needs, and with this, you are going to get the solution to this problem.

Ubersuggest solves this problem with its “Push Button” filter tool, that generally extracts keywords that contain specific terms or are within a specific range in terms of search volume, payment problem or search engine and CPC optimization as well.

Final Remarks on Ubersuggest  | What We Like Most?

For a free tool, the amount of keyword suggestions you can get with Ubersuggest is impressive, and you should definitely get started with it.

While Ubersuggest can provide hundreds of keyword suggestions, there are other tools that can do much more but we think you should definitely give it a try.

While doing the Keyword Research, Ubersuggest ensures that no important data is lost, even if it is a free tool.

However, your Keyword Research data can only be exported as a CSV file or copied to your clipboard and that is relevant as a free option.

4. Google Correlate

We all know that there is nothing better than seeking advice directly from the source. And again, I’m talking about Google one of the best search engine for several reasons.

Google Correlate is a tool that is often overlooked and can be extremely powerful to create a long list of keywords for free.

Google Correlate
Google Correlate

The main reason for using this tool is the ability to see what search terms are searched together. With this information, you can start to develop your list of keywords (especially the Longtails keywords) without putting that much of efforts.

The pattern generates the keywords, not the keywords that generate the pattern. So you have to think backward and understand what you’re doing.

Before continuing with the specific use cases of Google Correlate, let me make some comments on the warnings.

First, Google Correlate does not generate an absolute search volume and that’s the down part of it. Like the trends, it is based on the proportion of the total volume. All the terms are basically relative to each other. You should always use the Keyword Planner or another keyword search tool to search for a search volume of keywords in order to have better insights.

Here the fact is that the terms are related does not mean that they have a cause and effect relationship. The correlation data contains a lot of noise, but also many hidden gems. You must use your best judgment in order to hunt down the best working keywords for free.

Final Remarks on Google Correlate  | What We Like Most?

Google Correlate is an incredibly powerful tool. The use is not intuitive, such as Google Trends or Google Autosuggest but it’s worth a try.

Google Correlate is also a great complement to other tools. You can make informed decisions from public relations campaigns to cross-selling in your online store as well too.

5. is another popular tool in keyword research that comes for free.

At first glance, it may seem the vast majority of keyword search tools in the market, until you find that you can also search for keywords for YouTube, Amazon, Play Store, and other websites as well. And this one is the best option available.

The main difference is that shows the results of the keywords not in the search clouds, but in the traditional list view as well.

You can also filter the results as per your requirements. . It’s always a great way to diversify your group of keywords, find location options and create other content ideas easily without putting any efforts. also comes with the details like the average search volume, the CPC, the competitiveness rating and the traffic evolution of each keyword in the last 12 months and that I think you should expect with a reliable keyword research tool.

And if you wanted to have the pro version then you should pay $ 89 a month.

Final Remarks on  | What We Like Most?

Compared to other keyword search tools, the number of keywords you can get with is not particularly good. And it also lacking in monthly search volume of keywords as well. is recommended to find matching keywords for YouTube, Instagram, Google Play Store, Twitter, eBay, Amazon and Bing and as a free option available you should definitely give it a try.

But here the Pro measures a decent amount of metrics. Unfortunately, it is not difficult to find alternatives with many more functions at this price. You should try the free version and if you liked it then go get the pro version.

Now I’m going to list the best working paid keyword research tools available in the market.

6. Ahrefs

No doubt, Ahrefs is a well-known all-in-one tool that is used mainly used to scrape the backlinks. What most SEOs do not forget is that they can do much more. With its massive data index, Ahrefs is undoubtedly one of the most sought after SaaS tools in the market.

One of the best tools to easily grow your search traffic along with researching your competitors and monitor your niche as well.


 Tools like this have helped eliminate the extra efforts and time in doing effective search engine optimization.

They have helped the industry leader to become the best, and SEO has never been so easy. With tools like Ahrefs available in the market, it has been easy for SEO Evangelists to improve.

Even you can here remove keyword suggestions for YouTube, Amazon, Yandex and some foreign search engines.

In terms of results, Keyword Explorer implements a card-based approach. This makes each piece of information more presentable, readable and easy to find and that’s quite impressive.

The user experience in Ahrefs Keyword Explorer is slightly higher and smarter than that of the SEMrush Keyword Creator tool. Its structure is easy to organize, which makes the keyword data more readable.

Ahrefs offers all the keyword filter options that are indispensable for your research. You can also filter keywords based on the rate of return, which measures the users search for the same keyword within 30 days as well.

Final Remarks on Ahrefs  | What We Like Most?

Without having any second thought, Ahrefs has more keyword suggestions than SEMrush or any of the above tools. In addition, the keyword browser also creates keyword ideas for various search engines like Google, Yahoo, and Bing.

7. KWFinder

KWFinder may look like the Ubersuggest homepage. The main difference is that you can use KWFinder to search for phrases based on Google’s autocomplete questions and suggestions too.

Actually, I have used  KWFinder many times and it really helped me in finding the best keywords for my blog. On a page, not only are more keyword data loaded, but also the metrics are more accurate. The down part is that the interface is not like that of Ahrefs and SEMRush as here you have to scroll back and forth in order to access more data.


Keyword lists can also be created with KWFinder, an indispensable feature that a free tool like Ubersuggest can’t come up with. It’s not a cheap option available out there in the market.

In order to simply use the lists, check the boxes to the left of the keywords you want and click Add to list simply. You will be asked to create a new list if you have not created one yet and you’re done.

KWFinder is as relevant as you can get it with keyword search tools. All the information you need (keyword suggestions for your lists) is always available with two clicks and that’s quite impressive.

Some of the points that are worth looking:

First, with KWFinder, unlike Ubersuggest, you can search for keywords in a specific range of word numbers as well.

Secondly, with KWFinder, unlike Ubersuggest, you can hide the keywords that are already on your list and filter them easily.

Third, KWFinder will charge you at least $ 29 per month to access these filters, while Ubersuggest is free to use.

Final Remarks on KWFinder | What We Like Most?

For the keywords of the search engines, the results of KWFinder are comparable more and reliable to those of Ubersuggest. You may not get as many keyword suggestions as possible, but it will help in finding the less competitive long tail keywords.

As a paid keyword search software, the reporting features of KWFinder are much better than those of a free tool like Ubersuggest.

But you should also check the parameters like Search volume, average CPC, Keyword Difficulty, CSV Reports: all these reports are now available through Ubersuggest.

KWFinder is recommended to save keyword lists and view the search history of your account.
