If you're a small business owner, then you know how important it is to do keyword research.

It's the key to getting your website found online and generating traffic that converts into sales.

But what if you don't have the budget to hire a professional and can't spend on paid tools?

Don't worry - there are plenty of free tools out there that can help you get the job done.

Let's take a look at 10 of the
best free keyword research tools available to help you find just the right keywords for your website.

ahrefs keyword generator

The first free keyword tool in our list is Ahrefs Keyword Generator. It is a paid tool, but they offer a free keyword generator that can be used to get keyword ideas.

With Ahrefs Keyword Generator, you can generate up to 150 keyword ideas.

You have to enter your
seed keyword and it will generate your similar and related keywords, plus related questions that users might type in when searching for that seed keyword.

The free version also provides you with a metric, which is Keyword Difficulty. This is a metric calculated by how many backlinks the top websites have and it is on a scale from 0 to 100. The higher the number the harder it will be to rank for that keyword.

In our opinion, it is the best free tool at the moment!

google trends

Google Trends is another free keyword tool offered by Google and it can be a great way to get ideas for keywords.

Simply enter your main keyword and you'll see how that keyword has performed over time, including seasonality data, regional variations, and more.

This can help you identify trends in the market so you know what keywords to target to get the most traffic.

It can also help you create a seasonal content plan by looking at what people are searching for during different times of the year.

google keyword planner

The third tool on our list is the Google Ads Keyword Planner, a free keyword tool offered by Google that allows you to enter keywords and get keyword suggestions along with search volume for those keywords.

It used to be very good, but since then Google has modified how the tool works and instead of exact search volume, you can now only see a range of the search volume for those keywords.

It also shows the competitiveness of the keywords that it finds, but that is not the Organic search competition, it's the competition when advertising for those keywords.

If you have an ongoing campaign in Google Ads, it will show the exact search volume for the keywords.

It is still a very useful tool though, for generating keyword ideas!

Whether you have your own website or are considering starting a blog, this is one of the best tools available to help you find just the right keywords for your audience.

answer the public enter your query

Answer the public is a very unique tool that allows you to find questions that people are searching online.

To use the free keyword tool, simply enter your main keyword and it will generate a list of questions related to that keyword.

The results are divided into different tabs including Questions, Prepositions, Comparisons, Alphabetical, and Related Questions.

This is a great way to create content that directly responds to what people are searching for online.

It pulls its data from the autocomplete suggestions on the SERPs of Google and it can generate a good list of long tail keywords.

Unfortunately, it only gives you ideas, it doesn't give you data on the monthly search volume or competition, so you'll need to use that in conjunction with the other tools on this list.

keyword surfer

Keyword Surfer from the Surfer SEO team is a free Chrome plugin that shows you the estimated monthly search volume for search queries you enter into Google.

To use the tool, simply install the plugin and then do a search on Google. The results will show you an estimate of the monthly search volume for that keyword.

At the moment, Keyword Surfer 3.0 provides dataset from 70 different countries.

With this free Chrome extension, you can also generate NLP optimized content guidelines. You can use this to create
highly SEO Optimized content for the keyword you have searched for.


Keyworddit is another free keyword tool that you can use for keyword research.

To use the tool, simply enter a subreddit and it will generate a list of related keywords that people are using on that subreddit. It will look at the comments, titles to find the keywords.

Keyworddit can be a great tool to learn about a niche or a market that you don't know a lot about. It also can pull lingo that you might not find elsewhere and it might have a good search volume.

It gives you the estimated search volume for each keyword, plus it has a "Context" button which shows you the threads in that subreddit where the keyword can be found.


WordTracker is a paid keyword research tool which has a free plan for you to work with. With the free plan you can do 12 searches, which you can reset by browsing from incognito.

To get the keyword ideas, you have to enter a seed keyword. Each search will give you 50 keyword ideas, with historical data, search volume, competition and IAAT which mean In Anchor In Title.

This metric looks at how many websites have the keyword in their title and in the anchor of their backlinks.

The higher the number, the harder it will be to rank for a keyword.


Questiondb is a free tool that finds questions that people are asking about a specific niche or topic.

The datasource of this tool is reddit, which has a database of 48 million questions.

You simply enter a seed keyword and the tool will give you a list of questions related to that keyword.
