Top Ten Keyword Research Tools For SEO

If you have in mind to start a new website, make sure that you spend enough time on keyword research to guide your content strategy. By doing this you will have a clear idea as to where you want to take your site in the future and how to shape your content.

The basic foundation of SEO is keyword research. Fortunately, there are many tools available that can help you figure out which keywords work the best for your overall web strategy.  Most of these keyword research tools are paid and only a few of them are free.

Here is the list of tools listed below:

  1. Google AdWords: Keyword Planner
  2.  AdWord & SEO Keyword Permutation Generator
  3.   Google Correlate
  5.   Ahrefs
  6.  Keyword In
  7.   Wordtracker
  8.   KWFinder
  9.  SpyFU
  10.   SERPStat


1.  Google AdWords: Keyword Planner

The Google Keyword Planner tool is one of the most used and popular keyword research tools out there. The only reason for it being so popular is it’s free and is directly integrated with Google AdWords. To start using this tool you need to have an AdWords account.

Features: The biggest feature of the Keyword Planner tool is the deep information it offers on Google (the largest search engine).

Limitations: In some ways, that’s also a limitation. If you want to know how your site or a given keyword is doing on other search engines, you won’t get it here.

Pricing: Free to use.

AdWord & SEO Keyword Permutation Generator

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.

3. Google Correlate

Google Correlate is an often overlooked tool that can be extremely powerful for generating a large 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).


SEMRUSH is not a typical keyword research tool. It offers so much more than just researching keywords.

Unlike other tools where you need to add seed keywords to start your research, here you just need to add your URL (or your competitor’s URL) and it will show you all of the keywords that are ranking for that site.

This makes it easier for you to find short-tail and long-tail keywords that you can target and beat out your competition. You can get in-depth details on:

  • Traffic stats
  • Search engine reports
  • Adsense CPC

5. Ahrefs 

Ahrefs is one of the most popular keyword tools out there.
What I really like about them is extensive detail including the keyword difficulty. Ahrefs uses clickstream data to also show how many clicks you will get from the search engine. This is very useful after knowledge graph integration, as many keywords may have huge traffic but they hardly get any clicks from a search engine. Reason being, they get answers directly from the Google search result.

6.  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.

Keyword In is, by far, one of the simplest 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.

7. Wordtracker Scout

There are a lot of tools out there, including many on this list, that help you generate in-depth keyword lists. But, you could be missing the boat, if you’re not paying attention to what your competition is doing.

It goes without saying that you can visit any web page, such as a blog post on a competitor’s site and dig around for keyword data. After a few minutes, you should have a better idea of the primary and secondary keywords.
However, this can be time-consuming. And, you could also miss out on a few keywords, every now and again. Wordtracker Scout is a high-powered Chrome extension that ensures your success if this is a strategy that interests you.

8.  KWFinder  

If you are looking for one tool which is completely dedicated to Keyword research only, KWFinder is your best bet. They are new on the market yet they are one of the fastest growing SEO tool company.

KWFinder helps you get the Keyword that will help you drive highly targeted traffic. Using Questions based Keyword research option you can quickly find long tail keywords that are related to problem-solving. It’s no brainer that problem-solving content helps us get more targeted traffic & conversion.

9. SpyFU

SpyFu is one of the best SEO optimization software products on the market. It’s especially useful if you’re trying to analyze and stay ahead of the competition in a tight niche.

What you need to know about this one:

SpyFu is highly useful for understanding your competition’s SEO platform, and discovering under-served, untapped, or emerging markets.
It features :

  • Compare Websites module
  • Keyword History module
  • Domain History module
  • Related Keywords module

But it has its limitations because this program doesn’t have the depth of keywords that some competitors do, although this is changing. Also, the data for SpyFu is monthly, rather than real-time.

10.  SERPStat

Serpstat is another comprehensive keyword research tool that I discovered in 2018. They have done some really good work when it comes to helping us identify winning keywords. the Serpstat keyword tool gives you the following details:

  • Search volume
  • Competition
  • CPC
  • Keyword difficulty score

You have the option to search in based on country or also in Yandex search engine. The Keyword trends section help you to understand how the keyword search trend has been.

There is a detailed keyword difficulty score section that shows the top 10 web pages that have taken ranking for the keyword along with details like page rank, external backlinks and referring domains. These type of data is very useful when you need to evaluate if you can rank them for a specific keyword or not.
