5. Wordtracker Scout

While generating a cohesive and effective list of keywords is vital to SEO, it’s not the only aspect you should be worrying about. In fact, a large part of your SEO keyword research should be analysing what your competitors do. That’s where Wordtracker Scout comes in.

Wordtracker Scout, an umbrella application under Wordtracker, allows you to uncover the true keywords that attract your audience. Available as a Chrome download, you can visit any website and determine which keywords they’re trying to rank for. The Chrome extension will generate a summary of insights and keywords for that page.

6. Keyword Sh*tter

Generating new and fresh ideas for your keyword content can be tough. Especially when that writer’s block kicks in! Luckily, Keyword Sh*tter is here to help. All you need to do is input your seed keyword and press “shit keyword!” to generate a bulk keyword mine. As an added feature, you can filter your search terms by “positive” and “negative”.

For example, let’s put our seed keyword as “keyword research tools”. Then we’d input “free” as our positive filter.


As you can see, the results are only mining-related keywords with free in them.

On the other hand, the “negative” filter does the exact opposite. By inputting your negative filter, you are telling the tool to not include suggestions with that word in them.

This nifty tool is great for content generation. However, we do want to warn you that it can become quite an extensive list.


  • Customisable searches
  • Extensive results
  • Provides keyword data


  • Not specific to your location

7. SEMRush

We’ve saved the best for last – SEMRush is a top contender for those who aren’t looking to do massive keyword mines.

Enjoy all of the features that you’d expect from a paid research tool for free! The only catch is that you have to register and there are only 10 searches available per day. However, you do get to utilise the full range of SEO tools.

These tools are great for content and competitor research. SEMRush allows you to search either by domain or keyword. Based on your input, it will generate results for the keyword analytics, marketing insights, domain analytics and much more. You can even make use of the SEO Writing Assistant.



  • Accurate results
  • Extensive analytics
  • Full range of features


  • Only allowed 10 searches per day
  • Have to register for the services

There is a lot to be said about free keyword research tools! They save you time from mining appropriate keywords on Google and save you money from expensive platforms. However, paid tools do contain huge amounts of data and could be worth considering if you were to grow your SEO strategy.
