15 Free Keyword Research Tools For 2023 via @sejournal, @MaddyOsman

One of the biggest opportunities of search engine optimization (SEO) is performing keyword research and designing a content plan supported by the results of your research.

Keyword research helps you to:

Understand your target audience’s search intent. Gather information about related topics and questions searchers often ask. Monitor the current competitive landscape for your topic.

All of these things can affect your resulting content quality.

Keyword research is crucial in shaping your article’s structure and creating something that meets your customers’ needs.

But not all website owners do it. Many think it requires complicated or paid keyword research tools — but that’s not necessarily true.
