Keyword research has long been a key aspect of any effective content marketing strategy (although keyword stuffing should be avoided), and is the backbone of new content pillars and topical authority.
Using keyword research tools like Keyword Tool is brilliant for brainstorming new content ideas and concepts that also match your audience's search intent.
You need to ensure that the content you’re creating is what your audience wants to see. That’s where a keyword tool comes in.
They’re excellent for content marketing managers, small businesses, and even freelance content consultants who offer SEO as a service.
As mentioned, keyword research tools are fantastic for understanding what your target audience is searching online, allowing you to write content that keeps them engaged.
Creating great SEO-friendly content is not an easy process. After all, you’ve got to make sure it’s high-quality, unique, offers great insights, and meets all of the algorithm requirements.
So, you want to make sure that your audience wants to see what you’re creating, and that there isn’t too much competition in that area.
Keyword Tool is completely free to use with no paid plans, but there is a catch.
To access any of the important information, you need a Keywords Everywhere API key (see screenshots below).
To use the tool, all you have to do is enter your keywords into the search bar. You can enter as many as 10 or as few as 1 before hitting the magnifying glass to generate your results.
Here’s an example below from our search of ‘content marketing’:
You can then use the advanced filter to filter your results further if needed, before getting your final list of potential content ideas to work through.
As you’ll notice from the screenshot above, though, you can only get access to the monthly volume and traffic trends by putting in an API key.
So, while you can input a search into the tool, if you want to see the results, you’ll need an API key.
The Keyword research tool is the primary tool offered by the Keyword Tool platform, although you do need an API key to view results.
Within the tool, you can change the location you're targeting for more localized results, and also move from Google keyword research to YouTube and Amazon as well, which is helpful if you’re looking to create copy for those platforms.
While keyword research certainly plays a part in an effective content marketing strategy, it certainly isn’t the be-all and end-all.
Plus, with the constant updates to Google and AI Search, aspects such as authenticity, human voice, and content updates are becoming more and more important for digital success (learn more about the 2025 Google Search Quality Rater Guidelines).

Overall, the concept of having a free keyword research tool can be very appealing, but the particular offering of KeywordTool.net may not be suitable for everyone, especially considering that an API key is required to view the results of the keyword research. Further, it doesn’t offer several of the most important content marketing support tools that are essential in 2025.
