The KDI can be used to gain valuable insights into the marketability potential of any given keyword. It can be especially beneficial for marketers who are looking to gather more in-depth knowledge about a keyword's competitive landscape. For example, a marketer could use a KDI score to assess the most viable keywords for target audiences regardless of competition.

What Is Involved in Calculating a KDI?

In order to accurately calculate a KDI, a few different metrics need to be taken into account. A few examples include:
