Free Keyword Research Tools

This article talks about top 5 free keyword research tools based on my own experience with different tools. Read on to find out more on optimizing your website/blog using these tools.

SEO Book Keyword Suggestion Tool

This one stands at number one in my list of top 5 keyword research tools. I have been using this for years. There are two methods to use this tool. One is to use the online keyword research tool and other is to download its add-ons for Firefox. I prefer the online one as it provides more insight into the keywords.

Google Adwords Keyword Research Tool

Another good keyword research tool, Google Adwords, is designed specifically for Adwords users so that they can create their campaigns around the keywords suggested by Google. You can use this tool for optimizing your blogs and websites. The best way to use the Google Adword Keyword Research Tool is to use it without signing in. If you sign in, the resulting keywords will be biased – based on your own Internet usage. To get an unbiased view of what all keywords people are using, do not sign into the tool and use it as such.


The best thing about this tool is that you can add different filters to fine tune your keyword research. You can opt out of keywords related to adult content too. You can specify the category of your website and blog to get more customized results for your industry. You can also add your country if you wish to serve only locals.

ALEXA Keyword Research Tool

Unlike the above two tools that let you search for keywords for using with content, Alexa provides tools for researching different factors related to yours and your competitor’s websites. You can enter both yours and your competitor’s website into search box on Alexa to get a detailed report on:

  1. Traffic to the sites
  2. Keywords that pull traffic to the sites
  3. Global and local traffic rank (Alexa Rank)
  4. Inbound links
  5. Audience information and more


This provides for a detailed analysis that you can use to improve your sites’ ranking. It also allows you to click on the keywords to see who all are advertising on that keyword so that you get to know who all your real competitors are worldwide. You might love this feature not available with any other free keyword research tool.

Good Keywords –Desktop Software For Keyword Research

Good Keywords was the first software I used for learning SEO. It was probably the best because of its easy to use interface and detailed user manual. Earlier, it queried for keywords based on Google and some other search engines. Softnik redesigned the software so that it now works with Google Keyword Tool discussed above. You can either open Google Keyword tool manually or from the Good Keywords software. Once you export your keywords to a CSV file, you can import them into Good Keywords and play with them to find out the best keywords that suit your needs.

Among other features of Good Keywords are brilliant online articles that explain how SEO works and how you can use keywords and other things to optimize your blog or websites.

WordTracker’s SEO Blogger For Firefox

Wordtracker is a popular name when it comes to keyword research. It has a free keyword research option but that is limited to 20 searches per day and does not show competition among keywords (available with the paid version). It shows number of searches per month. You can use that or better still, download the SEO Blogger Tool For Firefox. This tool works with any blog writing software and suggests you keywords even when you are writing the blog.

Note that no single tool above is complete on its own though each might provide you with different details about different keywords. For best results, use more than one keyword research tools. Generally, I use the Google Keyword tool to get an idea of keywords and then put each keyword through SEO Book Keyword Suggestion tool to get further insights.
