Google has rolled out the Video indexing feature recently. For all my vimeo implementation I get the following warning:
Google could not determine the prominent video on the page
I noticed that Google shows me two Video URL sources
https://vimeo.com/sitemap_media_redirect?video_id=VIDEO_ID(Provided by video hosting platform)https://player.vimeo.com/video/VIDEO_ID(Source: HTML tag)
The video is implemented like this:
<iframe src="https://player.vimeo.com/video/VIDEO_ID" allow="autoplay; fullscreen" allowfullscreen></iframe>
Any idea how to solve this issue?
