File Size

File size is the amount of digital space an ad takes up, typically measured in kilobytes (KB) or megabytes (MB).

Why do we test it?

File size directly impacts ad load time, and larger files may lead to slower page loading, negatively affecting user experience. Ensuring that the file size meets the recommended limits ensures a fast-loading ad, which is crucial for improving engagement rates and reducing bounce rates on the publisher's site.
