Which term refers to a measurable indicator used to assess the results of a marketing effort?

The term that refers to a measurable indicator used to assess the results of a marketing effort is "Metric." Metrics are specific values that quantify an aspect of performance and can be used to gauge progress against specific goals. In marketing, metrics can include data points such as conversion rates, click-through rates, engagement levels, and return on investment. They provide marketers with the insight needed to make data-driven decisions and evaluate the effectiveness of their strategies.

While terms like "benchmark," "analytics," and "indicator" may relate to performance measurement, they do not specifically focus on quantifiable values. A benchmark typically refers to a standard or point of reference against which things may be compared or assessed, while analytics encompasses the systematic computational analysis of data, often involving metrics. An indicator is a broader term that signifies a sign or piece of information that suggests the state or level of something, but it is not as specific as a metric in terms of quantification.
