YouTubers generally don’t get paid if you skip ads, although there are some exceptions. Traditionally, advertisers pay YouTube per engagement (usually somebody watching an ad for at least 30 seconds). If a viewer skips before this time, YouTube doesn’t charge the advertiser or pay the YouTuber. If they click on the ad, the YouTuber gets paid. There are now non-skippable bumper ads of six seconds, charged on a CPM basis, i.e., per thousand views. They count if a viewer watches for at least 2 seconds.
