In order to decide whether to have autoplay videos on a newsfeed, there are several metrics that could be considered. One important metric to look at is engagement. This could include measuring the number of views, likes, comments, and shares on videos with and without autoplay. If autoplay videos are leading to higher levels of engagement, it could be a sign that users find them more compelling and are more likely to interact with them. Another metric to consider is user retention. If autoplay videos lead to users spending more time on the platform or returning more frequently, it could be a sign that they are having a positive impact on the user experience. On the other hand, if users are quickly scrolling past autoplay videos or becoming frustrated with them, it could be a sign that they are having a negative impact. It's also important to consider user feedback. Conducting surveys or user research to gather feedback on the use of autoplay videos could provide valuable insights into how users are responding to them. This could help determine whether autoplay videos are enhancing or detracting from the user experience. Ultimately, the decision to have autoplay videos on a newsfeed should be based on a combination of metrics and user feedback. By evaluating different metrics and gathering feedback from users, product managers can make informed decisions about whether to implement autoplay videos and how to optimize their use for the best possible user experience.
