Here in this blog, We are listing Top 11 Free Keyword Research Tools for SEO which are manually tested and used by us for doing SEO of websites. Start finding keywords without paying anything.

1. Soovle

Scrape suggested keywords from multiple sources.

Soovle gives you suggested keyword ideas from Google, YouTube, Bing, Yahoo, Amazon and more.
(All in one place)

That way, you can find untapped keywords that your competition doesn’t know about.

Soovle is one of the best free keyword research tools out there.

2. Jaaxy

Get thousands of related keyword ideas within seconds.

This is a straightforward (yet powerful) tool.

So, what makes Jaaxy unique?

First off, it gives you LOTS of different keyword ideas. (Including some that you won’t find in most other tools)
Plus, you get helpful data on every keyword that it generates (including competition, search volume and potential traffic).

You get first 30 search free of cost then you need to upgrade for more keyword research.

My Favorite Feature: QSR

QSR stands for “Quoted Search Result”.
This is a fancy way of saying: “how many other websites are trying to rank for this exact term?”.
Obviously, the lower this number, the better chance you have of ranking #1.

Jaaxy is a decent freemium tool. Not nearly as good as something like SEMrush or Ahrefs. But at $50/month, it’s not a bad deal.

3. Google Search Console

Find hundreds of “Opportunity Keywords”. The Google Search Console isn’t a traditional keyword research tool.
But it does have a feature that makes finding awesome keywords a CINCH.

The feature?

The Performance Report.

This report list out the pages on your site that get the most clicks from Google.
(And the exact keywords that brought them there)

So: how can you use this feature for keyword research?

It’s easy: use it to find “Opportunity Keywords”.

Opportunity Keywords are where you rank between #8-#20 in Google for a specific keyword. And with little extra on-page SEO, you can find yourself with a nice rankings boost.

For example, average rankings for the keyword “SEO tool” is 6.2.

That keyword is an Opportunity Keyword. And if I optimize my page around “SEO tool”, my rankings for that term should go up.

My Favorite Feature: Google Analytics + Google Search Console

Did you know that you can combine your Google Search Console and Google Analytics accounts?

Well, you can. And it’s VERY helpful.

When you do, you’ll get in-depth keyword data than you would with either tool by itself.


The Google Search Console is an underrated keyword research tool. No other tool can help you find Opportunity Keywords like the GSC.

4. Google Keyword Planner

Tap into Google’s massive keyword database.

The GKP is pretty vanilla compared to most other keyword research tools.

So why use it?

Because the data you get from it comes straight from Google. (So you know its legit)

My Favorite Feature: “Top of page bid”

This is how much people advertisers are bidding on a keyword.

For example, of you see a top of page bid of $10, people are spending an average of 10 bucks per click.
Obviously, the higher this number, the more commercial intent that searcher has.

The data in the GKP is the most reliable out there. That said, because it’s designed for Google Ads, using it for SEO can be tricky. This Google Keyword Planner Guide shows you how the GKP for SEO-focused keyword research.


Get boatloads of targeted keyword ideas. Here’s another Google Suggest scraper (just like UberSuggest and Soovle).

What makes KeywordTool unique?

Two things:

First, KeywordTool gives you A LOT of keyword suggestions.

For example, I just did a search for “SEO service”… and got 198 relevant keywords.

Not bad.

Second, you can easily filter, drill-down or expand the results to find the right keywords for you by filter the results and include negative keywords to filter out Unwanted keywords.

You can also Analyze Competitors and Check Search Volume in pro version.

My Favorite Feature: Analyze Competitors

This is a very cool feature I don’t see in many other keyword research tools.
Just enter a competitor’s site… and the tool will generate a list of keyword ideas based on that site’s content.

One of the best overall keyword research tools on the market. Worth a try.

6. Google Trends

Find new keywords and search trends.

There are two ways to use Google Trends for keyword research:

First, you can search for a specific keyword…

…and take a look at the “related topics” section.


Second, you can see if whether or not a keyword is growing in popularity.

Why is this important?

Well, let’s say you’re debating between two keywords: “Search Engine Optimization” and “Pay Per Click”.

As you can see, interest for “Search Engine Optimization” is growing fast… and fewer people are searching for “Pay Per Click” than ever before.

This isn’t to say that “Pay Per Click” is a bad keyword. But the fact that it’s trending down is one factor to keep in mind as you decide on your next keyword.

My Favorite Feature: News Search

See whether a given keyword is growing on the world’s news.

If you write lots of evergreen content, you NEED to use Google Trends. That way, you can see if a keyword is going to bring you traffic over the long haul… before you write a word of content.

7. QuestionDB

Find lots of question-focused keyword ideas (for free).

QuestionDB pulls question-focused keywords from threads on Reddit. So if you’re looking for an alternative to Answer The Public, QuestionDB does the job.

My Favorite Feature: Relevancy

Sort the results by relevancy. That way, you can create content that answers these burning questions.

With Relevancy, there are two other options like Topic and NEW for further accurate relevancy.
Note: You can see first 40 results in this. You have to upgrade for more results.

When it comes to finding question-keywords for blog content, QuestionDB can’t be beat.

8. Serpstat

Analyze the first page competition.

Serpstat is a SEO software suite with tools for content, link building, and more. Which means Serpstat doesn’t specialize in keyword research.

Even so, it still has a VERY decent keyword research tool.

My Favorite Feature: Competitors Graph

This lets you visualize the sites that are competing for a given keyword (and related terms). So if you see big bubbles for “Wikipedia” or “Amazon” it’s probably time to look for a different keyword.

Is Serpstat one of best tools on the market? No. But at $19 a month, you get a lot of pro features for your money.

9. Keyword Sheeter

Keyword Sheeter pulls thousands of autocomplete suggestions from Google.

To get started, enter one or more seed keywords and click “Sheet keywords.”

If you want to generate a lot of keyword ideas fast, this is the tool for you. It pulls around 1,000 ideas per minute, and you can export the results for free in one click.

The only downside to Keyword Sheeter is that it’s quite basic.

It doesn’t show search volumes or trends data, and it doesn’t group keywords as Keyword Planner does.

But it does have one other notable feature: positive and negative filters.

The easiest way to explain how this works is to show an example. So let’s add “how” to the positive filter.

Now it only shows queries that contain the word “how”—i.e., informational keywords that might make for good blog posts.

The negative filter does the opposite and excludes queries containing certain words.

This is useful for eliminating anything irrelevant. For example, if you run a tech blog and scrape results for “apple,” then you probably only want to see keywords relating to Apple the company, not the fruit.

So you could exclude keywords like “pie,” “crumble,” “fruit,” and “cider.”

10. Answer the Public

Answer the Public finds questions, prepositions, comparisons, alphabeticals, and related searches.

Confused? Let’s tackle each of these one-by-one.

We’ll start by entering a “seed” keyword—let’s stick with “protein powder.”

The first thing you’ll see are questions.

These are search queries containing who, what, why, where, how, which, when, are, and is.


• what protein powder tastes best?

• how protein powder is made

• are protein powders fattening?

• when does protein powder expire?

You’ll see a visualization by default, but you can switch to a regular list.

Next up, we have propositions—i.e., for, can, is, near, without, with, and to.
These are search queries that fit the [seed] [preposition] [______] format.


• protein powder without carbs

• protein powder for weight gain

• protein powder is it safe

We then have comparisons—i.e., versus, vs, and, like, or.
Once again, the format is [seed] [comparison] [______].


• protein powder versus meat

• protein powder or chicken breast

• protein powder like quest

And finally, we have alphabeticals and related.
Alphabeticals are Google autocomplete suggestions.

And related, well, who knows?

In my experience, the number of suggestions in the related category is almost always ~20. I have no clue how it derives those keywords. But it does kick back a few gems from time to time.

But where does ATP get its data from?

As far as we’re aware, that would be Google Keyword Planner and Google autosuggest.

11. Keyword Surfer

Keyword Surfer is a free Chrome extension that shows estimated global and monthly search volumes for any query typed into Google.


Keyword Surfer works much the same way as another popular extension called Keywords Everywhere. This tool used to be free but recently switched to a paid model. Keyword Surfer’s developers have promised to keep this tool “100% free, forever.”

Right now, Keyword Surfer shows local search volume estimates for 19 countries. These include the United States, the United Kingdom, Canada, Brazil, France, and Germany.

There’s also an option to turn global search volumes on or off.

That said, these aren’t true global search volumes. It’s the total sum of searches from the 19 countries currently in their database.
Beyond this, the extension also adds search volume estimates to the autocomplete results:

And shows 10 “similar” keywords in the search results:

The only downside is that there’s no way to get search volumes in bulk.

That said, bulk research isn’t the aim of this extension. It’s more for assessing queries as you browse the web.


There you have it: 11 of the best free keyword research tools.
