Keyword research is the pillar of the SEO industry, and it is also one of the starting points when creating an appropriate content strategy that connects with your target audience. Performing keyword research reveals to you the true search intent of your audience, the topics and frequently asked questions people search for and the competitive environment in your desired topics. Despite the fact that each of these attributes contributes to the quality and usefulness of your content.
