Load Size: Total

Load size is the total amount of data (like images, scripts, and files) that your ad uses when it loads. Ads with too much data can take longer to show up.

Why do we test it?

If an ad takes too long to load, users may not see it. By keeping load size small, ads can appear faster, which means more people will notice and engage with them.
