File Size

File size refers to the amount of data the file contains, measured in kilobytes (KB) or megabytes (MB). Large files can take longer to load, affecting ad performance.

Why do we test it?

File size has a direct impact on ad load times and overall user experience. Large files can lead to slow loading ads, increasing bounce rates and reducing user engagement. This test ensures that file sizes are optimized to strike the right balance between quality and performance, making ads faster and more efficient while avoiding penalties from ad networks that impose file size limits.
