Here are a few common questions about keyword research.

What is keyword research?

Keyword research is the process of finding keywords that your target audience searches for on a given platform. With keyword research, the goal is to develop a list of keywords you can then use to create content. 

Why is keyword research important?

Keyword research is essential for any online operation. Since keywords are the terms that users search online, you need to know them to create content that ranks. They are also the backbone of SEO and help your pages rank in relevant search results.

Keyword research helps you avoid creating content for the wrong audience as well. If you know what your ideal user wants to see on your site, you will have better luck attracting and converting them.

Should I use a free or paid keyword research tool?

Whether you use a free or paid keyword research tool depends on your budget and needs. 

Many free tools have basic keyword research capabilities that can help you get started with keyword research. However, if you want something more in-depth and have the room in your budget, investing in a paid one helps you get more data on keywords.
