If you're planning to use your display banner for social media ads as well, it's a good idea to make a few changes so it fits better. Social media is more fast-paced, so your design should be simple and straight to the point. Keep the text short and make sure it's large enough to read on a small screen. Place your main message and call-to-action where they won't be covered by buttons or cut off in different formats. Bright colors and bold visuals can help your ad stand out while people are scrolling. Also, since people often browse with sound off, it's better to avoid designs that rely too much on audio. Have you tried adjusting banners for both platforms before?
