It will assist you in finding all the best possible keywords relevant to creating content for your business. Simply by entering a main word or website URL, you will be able to obtain several related keyword suggestions according to your target audience and industry.
  • Researching and Prioritizing the Keywords: The next thing these tools do is research and prioritize the right keywords. They will display a proper insight into the search volume of all keywords, i.e., how frequently some specific words are searched and how the exact google searches have altered over time.

QuestionDB 

QuestionDB 

Last but not least, QuestionDB is a free tool that discovers questions asked by netizens and produces question-focused keywords out of them. It mostly pulls out such questions from the threads of Reddit. The questions are chosen based on popularity and are best for use in blog-type content as question keywords.

Free vs. Paid Keyword Tools: How do they compare?

Both the free and paid keyword tools are beneficial in their own ways. However, free keyword tools have certain limitations in comparison to paid keyword tools.

The amount of suggested keyword and accessible data provided by Free Keyword Tools is inferior compared to the data generated by Paid Keyword Tools. Even the database on which the Paid Keyword Tools run their programs is far more extensive than the Free Keyword Tools.

The Paid Keyword Tools also display several estimated data related to CPC, monthly search volumes, clicks, KD (Keyword Difficulty), and more. This makes the process of searching, filtering, and selecting keywords far quicker with the help of Paid Keyword Tools.

Due to the above reasons, Paid Keyword Tools are preferred over Free Keyword Tools, especially while dealing with highly advanced content and keyword research.

Final Thoughts

Though all the above-mentioned keyword research tools have their own share of benefits, one should determine their budget and analyze their brand objectives and content goals to select the best keyword research tool.
