13 Unique & Free Keyword Research Tools You Didn’t Know You Needed

You may already have favorite paid and free keyword research tools for SEO – but don't count these unique keyword research tools out.

13 Unique & Free Keyword Research Tools You Didn’t Know You Needed

One of the biggest SEO mistakes you can make is neglecting keyword research in favor of producing “great content.”

That’s because you need keyword research to pinpoint where your customers are at in the customer’s journey.

In general, a person searching “How to do [something]” is seeking information, while a person who enters “[product] sale” is looking to buy the product.

Using that information, you can produce relevant content that gets customers to click through and convert.

In a nutshell, keyword research determines the keywords that matter most for the objectives of your website.

When done well, it provides direction as to what you should be optimizing for awareness, consideration, or conversion.

Due to Google’s popularity, most SEO professionals first turn to Google Keyword Planner and its related tools, which can be limiting or difficult to use.

The good news: Several free keyword research tools are available in the market.

Don’t ignore uncommon keyword research tools that are ideal for when you are in a rut and looking for additional options.
