Which metric is commonly used to measure engagement with digital content?

Click-through rate (CTR) is a widely recognized metric for measuring engagement with digital content. It calculates the percentage of users who click on a specific link or call-to-action, reflecting how effectively the content captures interest and drives user action. A high CTR indicates that the content resonates well with the audience, prompting them to engage further.

This metric is particularly valuable in digital marketing as it provides insights into the performance of advertisements, email campaigns, and website content. By examining CTR, marketers can assess the effectiveness of their messaging and make necessary adjustments to improve audience engagement.

The other options—cost per click (CPC), return on investment (ROI), and cost per acquisition (CPA)—focus on different aspects of performance measurement. CPC measures the cost incurred for each click on an advertisement, ROI evaluates the profitability of investments compared to costs, and CPA calculates the cost associated with acquiring a customer. While important for assessing campaign efficiency and financial success, these metrics do not directly measure how engaged users are with the content itself.
