Yep. Ad viewability standards simply require that a video ad was 50% onscreen for a continuous 2 seconds in order for it to count as an impression. Google probably usually gets that even for skippable ads.

> Picture this: an advertiser pays premium rates for space on your site, but their carefully crafted creative sits unseen at the bottom of a page your readers never scroll to. Despite technically delivering the impression you promised, you've essentially sold empty air. This disconnect between ads served and ads seen is why viewability has emerged as the cornerstone metric in digital advertising's maturity.

> Video ads require at least two seconds of continuous play while 50% visible ... These seemingly arbitrary thresholds represent extensive research into human attention patterns.
