When creating responsive ads, which guideline should you follow?

• A. Preview multiple ad placements
• B. Run only on mobile
• C. Avoid call-to-action
• D. Use a single image size

Answer: (A)

Previewing multiple ad placements is essential because responsive ads are designed to adapt to a variety of formats and sizes. By previewing, you can verify that your assets—headlines, descriptions, logos, and images—render correctly across different placements such as search results, the Display Network, and Gmail. This helps you catch issues like cropped images, truncated text, or imbalanced visuals before you publish, improving the ad’s readability and potential performance. Running only on mobile narrows reach, while avoiding a call-to-action reduces motivation for users to engage. Using a single image size goes against the flexible nature of responsive ads, which rely on multiple assets and sizes to fit different placements.
