Time to Visual Start

This is the time taken for the first visible part of the ad (often the first pixel) to appear on the screen.

Why do we test it?

If it takes too long for an ad to show up, users might scroll past before it even appears. By making sure the ad shows something quickly, you increase the chances that people will actually see it.
