Creative Border

A high-contrast border is often required for ads, particularly for images that blend into the background, to ensure they stand out.

Why do we test it?

A high-contrast border helps ensure the ad catches the viewer's attention, avoiding the issue of blending into the website background. This is particularly important for compliance with certain ad networks, which may require clear differentiation between content and ads. Adding this border can also enhance the overall visibility of the ad.
