What Is Keyword Research?

Keyword research is the process of discovering and evaluating the words and phrases people use when searching, to guide what content a site should create.

Example

Before writing an article, a content team might use a keyword tool to compare “email marketing tips” against “email marketing strategy,” checking search volume and difficulty to decide which term to target as the primary focus.

Why it matters

Keyword research grounds content decisions in actual search demand rather than guesswork, helping teams prioritize topics that real audiences are searching for and avoid spending effort on terms with little to no search interest. In practice, that means weighing search volume against keyword difficulty and intent together, not any one of the three alone.
