Which metric would not typically be classified as a performance indicator in digital marketing?

Market share is a broader metric that measures the percentage of an industry's sales that a company or product holds compared to competitors, reflecting a company's overall standing in the market. This metric encompasses not just digital marketing performance but also factors such as brand reputation, customer loyalty, and competitive dynamics.

In contrast, engagement metrics, website traffic, and conversion rates are direct indicators of performance in digital marketing initiatives. They provide insights into how well marketing strategies are performing in real-time by showing user interactions, the number of visitors to a website, and the effectiveness of turning visitors into customers, respectively. These metrics are crucial for assessing the efficiency of campaigns and making data-driven decisions to optimize marketing efforts.
