Load Size: Initial

Initial load is the amount of data your ad loads when it first appears on a webpage.

Why do we test it?

A fast initial load helps the ad show up quickly. If the initial load is too big, the ad may take longer to display, and people may scroll past without seeing it. Keeping the initial load small makes sure the ad is visible quickly.
