What is Google Discover?

Google Discover is a personalized content feed on Google products (primarily on Android devices and within the Google App) that displays articles, videos, and other content based on a user's interests, search history, location, and Google activity. It aims to provide users with information they may find relevant and interesting without them having to actively search for it. It is commonly used to increase website traffic by having content surface to users who may be interested in it. Unlike Google Search, Discover focuses on surfacing content related to topics users are interested in, even if they haven't explicitly searched for them recently.
