Hashtags are pervasive on numerous online social media platforms nowadays. With respect to Google’s own services, Google+ had hashtag support before it was killed off, and YouTube has had them for almost three years now. Discover is the most recent Google service to try different things with hashtags, however it appears to be somewhat unnecessary.
The implementation in Discover is to some degree like how YouTube shows them, with several hashtags appearing close to the bottom of each card. These hashtags are somewhat useless.
All things considered, on the off chance that you would like to see more content about said hashtag, you can tap on it to see more pertinent articles and videos. Tapping on the #FlatSixEngine hashtag shows some more content that Google thinks you’ll like.
For the time being, these hashtags appear to be part for a genuinely restricted A/B test.
