Best Free Keyword Research Tool

1. Google AdWords: Keyword Planner

The most obvious choice for the top spot, this free keyword tool has been a favorite for many years.

Not only is the Google Keyword Planner a right choice when starting a new site, but it can also be your best friend as you grow and produce more content.

The primary benefit of this tool is easy to see: you’re able to pull information directly from Google, which is the search engine you’re most likely to target when optimizing your website.

The first step is as simple as entering your keyword or keywords into the search box.


From there, everything you need is laid out clearly and concisely.

In addition to your search term(s), you’re provided with many other ideas. Some of these will work, some won’t. Either way, you want to pay close attention to all of the keywords. You never know when you’ll find a gem.

Along with the keyword list, you’ll find:

  • Average monthly searches
  • Competition
  • Suggested bid (if you’re using AdWords)

I’ll be the first to admit that the Google Keyword Planner doesn’t do anything special. However, it does everything right, and that’s what matters most.

If you’re seeking keyword data from the source, you can’t go wrong with this tool.


2. AdWord & SEO Keyword Permutation Generator

Are you struggling to uncover new keywords in your keyword research?

This is a challenge that you may face when launching your new site. While you’re familiar with the top keywords in your niche, you don’t know where to go from there. And, as you know, that can be a problem as you create more content.

Consider this keyword tool a great way to help.

With the AdWord & SEO Keyword Permutation Generator tool, it’s easy to get creative as you search for keywords that align with your site, marketing strategy, and goals.

The thing that I like best about this tool is the way that you can get creative. You can enter a keyword in each of three boxes, hit “generate permutations,” and watch the magic happen.

Here’s an example:


As you can see, the more keywords you add into the first three boxes, the more results you’ll receive.

The only downside to this tool is that some of the keyword results may not make sense. For this reason, you must be prepared to spend a reasonable amount of time moving through the list, searching for those that best suit your site.

If keyword creativity is an issue for you, let this tool be your guide. It’ll point you towards some ideas that you may not have previously considered.

3. Google Correlate

As noted above, there’s nothing better than getting advice straight from the source. And, once again, Google is the source I’m talking about.

Google Correlate is an often overlooked tool that can be extremely powerful for generating an extensive keyword list.

The primary reason to use this tool is the ability to see which keywords get searched together. With this information, you can begin to grow your keyword list (especially longtails).

In the example below, you’ll see that people who search for “diet plan” also search related phrases:


So, while a diet plan may be your primary keyword, there are several others that you can focus on as you create your content calendar. For example, you may decide to create a blog post based on some or all of the “correlations.”

If you find yourself in a keyword rut, Google Correlate can help you escape. You enter your primary keyword. From there, the tool does all of the work for you.

4. IMforSMB Bulk Keyword Generator

Some keyword tools are suitable for every type of website. Others, however, are only a good fit for a particular site type.

This is where the IMforSMB Bulk Keyword Generator fits in. This tool works best for local service companies, as it’s designed with the idea that you’ll want to find local keywords.

Using the tool begins with selecting a category:


From there, take the time to choose your service type carefully:


Finally, enter your service location and click “Generate Keywords.” Then, get ready to be mesmerized by the results.


These results aren’t anything special, as you could eventually come up with the same keyword list by using another tool. However, with its local approach, you’ll feel as if you’re on the right track quickly.

Pro tip: even if your business type isn’t available, you can still use this tool. You’ll have to replace some of the keywords with your own, in the search results.  But, you’ll end up with the same primary results.

5. Keyword In

If you want to “combine your keywords the easy way,” you’re in the right place.

It all starts with a long tail (or seed) keyword or keywords. From there, this tool mashes everything together to provide you with a long list of potential keywords.

Here’s the example shared that’s when you first visit the site:


Once you hit the “generate” button, you’re shown the following:


Keyword In is, by far, one of the most straightforward keyword research tools to use. It only takes a couple of seconds to plug in your keywords, choose your options, and generate results.

You may not always like what you see, but it’s easy to double-back and change your seed keywords. The more you do this, the more results you’ll generate.

Pro tip: experiment with each match type, including broad, phrase match, and exact match.

I like keyword tools that are easy to use. Furthermore, I always tell people who are launching a new site to keep things as simple as possible. With Keyword In, you get the best results without any complications.


When it comes to keyword research, there’s a right and a wrong way of performing your analysis.

Rather than guess and hope for the best, I urge you to experiment with all 10 of these free keyword research tools. Doing so will go a long way in ensuring that you choose the right keywords for your new site, thereby guiding your content strategy, increasing your ranking with search engines, and edging you closer to success.
