Strong visuals are often the single biggest factor in whether someone stops scrolling to notice your ad. This lesson covers best practices for ad creative — using bright, high-contrast visuals, keeping text on images minimal, and designing for the platform (square or vertical formats tend to perform better on mobile feeds and Stories/Reels). It also covers the growing importance of video ads, particularly short-form vertical video, and how the first 2-3 seconds of a video ad are critical for stopping the scroll and holding attention.
