Quizplus · Accepted Answer

Copytesting is a process of testing an ad before it runs by presenting it to a sample audience to determine the effectiveness of its content and message. This helps marketers to spot any issues with the ad and make necessary changes to improve its overall impact. Other options such as narrative testing, concept evaluation, brainstorming, and comparative analysis may be useful in developing an ad, but they do not offer the same level of insight as copytesting.
