In a campaign analysis, what primary factor should be evaluated when measuring customer interaction with forms?

Evaluating the completion rates of forms submitted is critical in campaign analysis because it directly indicates how effectively a form is engaging users and driving them to take action. Completion rates measure the proportion of users who successfully complete the form compared to those who start it, providing insights into the form's clarity, user-friendliness, and overall effectiveness in compelling users to finish the interaction.

High completion rates suggest that the form is performing well and that users find it relevant and easy to navigate, which is essential for campaign success. This metric helps in identifying potential issues, such as if users are dropping off at specific points in the form, which can indicate opportunities for optimization.

While factors like time taken to fill out forms, user demographics, and device types are also useful for in-depth analysis, the primary evaluation focus should be on completion rates since they directly reflect user engagement and the effectiveness of the form in achieving its intended purpose.
