Did you land here searching for the keyword research tools that you can use? Then make sure to read this article as we have listed down some of the best tools that could help you in performing keyword research and pick the right keywords that have great potential to drive traffic to your blogs.

Millions of blogs are published online regularly by bloggers with the main goal to drive organic traffic from search engines. One can get traffic for free from them on a consistent basis as long as the web pages rank higher in the search engines.



Additionally, spending more time on keyword research wouldn’t just help you gain traffic but you would be able to plan a good content strategy for your website. You can get new content ideas that you might not get just brainstorming. 

Even though you can easily do keyword research, picking the right keywords that can drive traffic to your website isn’t that easy. You should understand the intent and check if your content can rank higher in the search engines competing with the other websites that are ranking for a keyword.

Depending on your budget and affordability you can use either free or paid keyword research tools. However, mostly paid keyword research tools provide more valuable insights about a particular keyword than a free keyword research tool that makes it easy to select a keyword.

So we have listed some of the best keyword research tools below:



With billions of searches being made on popular search engines like Google and Bing, autocomplete suggestions are highly useful to understand the phrases used around a particular keyword. Answer The Public is a great tool that can help in finding such search queries especially long-tail keywords in a visualized manner.

Using this tool you can get a lot of content ideas that can help in performing keyword research and plan your content strategy.All you have to do is enter the primary keyword related to your niche selecting the country where your target audience resides as shown in the image below.

When you enter a keyword it shows the data of the search queries using that particular keyword under 5 sections Questions, Prepositions, Comparisons, Alphabeticals, and Related Searches. 

Didn’t get what they are? Well, then let me explain each section in detail with an example.


The first one is the “Questions” section under which the keyword suggestions that get started mostly with Question Words like Why, What, When, Where, etc are displayed.

For example, when the keyword “start a blog” is entered there are many Questions shown up as you can see the results obtained in the form of a visualized cloud.


However, if you feel overwhelmed with the visual display of results, you can easily utilize the DATA tab as shown in the image below

Keyword Tool is my favorite because this shows the data related to social media platforms apart from the search engines. Entering a seed keyword, you can get the keyword-based search terms selecting the search engine of your choice that is mostly used by your target audience.

Here I have selected Google as my search engine and when “Start a blog” is used as the main keyword, the keyword tool displayed 232 unique keyword ideas as shown in the image.

Semrush is an All In One Digital Marketing suite of tools that can help you with many things like SEO, Competitor Research, Social Media Scheduling, Lead generation, Content Writing, Digital Advertising.

Using the keyword magic we can find the search volumes, Keyword Difficulty score, CPC, Trends , etc that can be highly useful in picking the keywords. It also provides you a tool called keyword manager to save and easily export them later.

Even though the tool has a large set of tools, it still offers a free plan with some limitations on accessibility. I would recommend you to get started with this as it is one of the best tools out there with a free plan.

Ahrefs is similar to Semrush with a suite of tools that can be highly useful for content, keyword and advertising research. It has a tool called Keywords Explorer that can provide you the keyword data from different search engines like Bing, YouTube, etc apart from Google.

Ahrefs is one of the most preferred tools by many bloggers as it can provide a lot of information about clicks on the results that are essential in picking the potential keywords that can drive traffic to a blog. Remember you cannot drive traffic to your blog even though you rank higher when most people don’t actually click on the results.

When I have entered the keyword “start a blog”, it has provided the estimated clicks data along with the search volume and other metrics. Here the search term has a keyword difficulty score of 84 which according to ahrefs is hard to rank.

Also, there are many keyword ideas with the same terms and questions displayed below that can be viewed and filtered based on the metrics like Keyword Difficulty, search volume, etc. You can also export the keywords just saving them in the form of a spreadsheet with all the keyword data.

But Ahrefs has no free plan like Semrush and there is only a free trial that you can get for a week. So if you are just getting started and looking for an affordable solution then Semrush would be a great choice to get started with keyword research.

Final Note:

Publishing quality content without making a research about the type of content your target audience is looking for might not help in reaching the target audience. Using keyword research tools in the right way you can get new content ideas and potential keywords that are easy to rank higher driving more traffic to your blog.
