Javier designed a new Carousel Ad to support his company’s new product launch. Which two actions should he take before he launches the campaign?

Explanation: The correct answer is to **"Ask a colleague to review the creative"** and **"Build the campaign so that he can test one variable at a time"**. Before launching the Carousel Ad campaign, Javier should seek feedback from a colleague to ensure the creative aligns with the brand's messaging, is visually appealing, and effectively communicates the key features of the new product. This step helps catch any errors or inconsistencies that may have been overlooked during the design process. Additionally, building the campaign to test one variable at a time allows Javier to assess the impact of individual elements such as images, headlines, and copy on the ad's performance. By systematically testing each variable, he can identify which elements resonate best with his target audience and optimize the campaign for maximum effectiveness. This approach enables Javier to make data-driven decisions and refine the Carousel Ad to achieve the desired objectives of the product launch campaign.
