Google is making its flagship search product more personal with a revised feed that the company launched today. The updated feed — a lineup of cards personalized to each user’s interests — will first appear on iOS and Android, before expanding to other platforms. Users’ feeds are based on each person’s use of Google services. The factors that affect what content is shown in a feed include users’ search histories, YouTube watching habits, and activities in Chrome. In addition, users can choose to follow topics that they care about, like Labradoodles, health care policy, professional cycling, and more.
