2 months agoHow Google Picks Image Thumbnails In Google Search & Google Discover
Google's selection of an image preview is completely automated and takes into account a number of different sources to select which image on a given page is shown on Google (for example, a text result image or the preview image in Discover). You can influence which image gets selected by providing your preferred image through one of the following metadata sources: Specify the schema.org primaryImageOfPage property with a URL or ImageObject, or specify an image URL or ImageObject property and attach it to the main entity, or specify the og:image meta tag.
