The increase in view time for YouTube Shorts is a positive sign for the platform, as it indicates that users are engaging with the new short-form video format. This could be due to the fact that Shorts are prominently featured on the YouTube homepage, making it easier for users to discover and watch them. However, the decrease in watch time for YouTube overall is cause for concern, as it suggests that users may be spending less time on the platform or watching fewer videos. As a product manager, it would be important to investigate the root cause of this decline in watch time and develop strategies to address it. This could involve improving the recommendation algorithm to surface more engaging content, enhancing the user experience to make it easier to find and watch videos, or exploring new content formats to attract and retain users. Ultimately, the goal would be to increase user engagement and drive growth for the platform.
