Google Discover Tests Marking Each Article with Hashtags
https://9to5google.comGoogle Discover is now testing applying hashtags to every article in the feed. The hashtag appears just after the article description and above the website’s favicon, name, and publish time. Some articles just have one for the company being discussed, while others specify a very general category. Google is presumably the one assigning the hashtag, with websites having no obvious control over what appears.
