I have embedded a
<video> in the header of a website. It is only used for cosmetic reasons and is present on almost all sub pages.
Now I noticed that whenever I enter a search term in Google's Everything Search, some of the links to my page (including the actual landing page) are displayed as a video result, with the 12-second video thumbnail included.
Of course that doesn't fit the page's content at all, since the video is far from a core element on this page.
How can I prevent Google from showing my results this way? Other questions only seem to deal with adding a video, whilst I want mine removed.
