Just to add a supplemental to what Mr. Kee just said, on your Google account writ more largely, you can go into “myaccount” and it will identify what we've identified as your interests across all of our products and services. You can go to myaccount and it will say in general terms that you like 1980s music and racing videos. It will give you that general observation, which you can then correct. You can delete that information or you can add in additional interests so that across our services we have a better understanding of what you're interested in and, as well, what you don't want us to serve.
On the page itself, there is a little three-dot bar beside the videos, the specially recommended videos—on mobile, as you mentioned—where you can signal that you're not interested in that content or that you would like more of it. There is granular control to not seeing that in your video feed, your newsfeed or across Google services.
