I added product videos in the "Images and Videos" section of the product and they get displayed on the frontend.
Problem is as long as i don't click on the video-image/thumbnail the video only gets displayed as an image resp. Google recognizes the video not as a video but as an image. Is there anyway to change that so Google recognizes the product videos as videos when it crawles my shop?
if want to rightly craw product video, you may use schema. For the product data, you must try add your product details inline with schema in your head tags to inform google to know about your product details, imageObjects, etc.
I hope this will correct your crawling perfect.
Sorry i am new to Magento. I don't understand how to implement what you meant and i also don't really understand how that helps Google to find videos on the product page when it crawls and indexes the product.
