Find out the best free SEO tools for keyword research to level up your content marketing game!


Keywords are queries that internet users type on search engines. The pages with the relevant keyword appear on the top of search results. Consider, keyword research is the fundamental building block of applying search engine optimization (SEO) best practices. 

You may write the best ever content without using a single keyword. But your page won’t show up on the top results of search engines. To remove the guesswork and save time, digital marketers use various paid and/or free online tools. To discover and analyse marketable phrases and words, here are the 10 best SEO tools for keyword research. All of them can be used for free!

Google Keyword Planner

A proprietary Google SEO tool, Google Keyword Planner is free to use. All you need is to have a Gmail id that you can use. 

Google Keyword Planner

By clicking on the ‘Discover new keywords’ section, you can enter a relevant keyword. You can filter out keywords based on search volume and use them in your content. 

Google Keyword Planner gives you the list of keywords, their monthly search volume range and shows you the competition you want to rank for. 


This powerful and affordable keyword tool from Neil Patel packs in tonnes of features. It also has a Google Chrome extension that you can install. 

Here you can just type a topic or a keyword and select the location where you want to target your website. Head over to the Keyword Overview section and find a list of keywords related to your search query that you can include in your content.


Ubersuggest pulls out data from Google Keyword Planner, but it differs from the native Google platform. It gives you the exact number of searches and offers various Content Ideas based on the keyword you choose. 

You can use Ubersuggest for free but it comes with a daily limit of three keyword searches. 


This search listening tool understands what users type or speak on search engines such as Google. 


The tool is extremely easy to use and understand. Just type in the keyword, choose the location and language before hitting the Search button.

You can arrange the results based on questions, comparisons, prepositions, and more. The questions section covers who, what, when, why and how. The prepositions section include the primary keyword along with another query with a preposition. And so on. 

Keywords Everywhere

The best part about using this tool is that it shows you the keyword stats on other sites apart from the Google search engine. They include platforms such as YouTube, Amazon, Etsy, Instagram, etc.

It offers both free and paid versions. Both of them provide a list of ‘Related Keywords’, “People Also Search For’ and ‘Long-Tail Keywords’. But the free version does not show you the search volume for any of the sections.

A Google Premier Partner, WordStream offers a free keyword tool without any paid subscriptions. It sources results not only from Google keyword search API but also from Bing.

And you can filter keyword results from different 23 countries and 25 industries to narrow down the search even more. You will find more keyword ideas by choosing the email option. 


The purpose of any keyword tool is to help you find keywords that you can improve your content with. QuestionDB shows you what users ask based on the keyword. 

While you can use any of the keyword tools mentioned so far, use this to cover the common queries to create a relevant content outline. 


If you are going for its paid version, it is much more affordable than AnswerThePublic’s premium solution. But you can also use it for free which has a limitation of 50 questions. 

Best for local SEO, Google Trends offers real time information on topics people search on the native search engine.

Google Trends is also beneficial for finding topics in your niche. You can filter out a topic, see which regions it is trending.

 And this keyword tool is completely free without limitations.
