They surely get analytics on how well a sponsorship works since they use dedicated URLs. And if a sponsorship does not produce a return on the investment, the sponsor will stop giving money to the content creator.

I would also guess there's some watch time data access through the YouTube API, too. Plus tracked links in those cards at the corner of a video.

YouTube does show the creator/uploader engagement throughout the video, so you can tell if there are less viewers for sponsor segments. My point is that info isn't necessarily shared through to the advertiser

What I mean is, it's entirely possible for sponsors to ask for channel data.

The sponsor segments are ads. You're getting doubled-dipped.

And that's why I've been using this sponsor block plugin.

I thought about using that plugin, but I'll be missing out on the creative sponsored ads done by some YouTubers like Daniel Thrasher (plus his sponsored section is at the end so I can always skip them anyway).

Does YouTube share a part of your premium/fee to the creators based on what you watched? That is actually pretty neat.

That is my assumption and it would be shocking if that were not the case. This is the case for ad revenue. Youtube premium replaces ad revenue with a fee.

The interesting question I'd like to know the answer to is if creators get more money per ad impression or per premium subscriber view.

Creators are paid "a majority" of revenue from YouTube premium based on watch time.

Do demonetized channels get their share? A couple of channels I watch swear a lot, and are demonetized. It's a bliss to watch YouTube without ad interruptions. I don't mind product placement by the content creators. I would be happy to pay if I knew they are paid too.
