As a product manager, setting goals for any feature or product is crucial for its success. In the case of Facebook Marketplace, the goals should align with the overall business objectives and user needs. The following goals are essential in building a successful "Products You May Wanna Buy" feature on the Newsfeed: 1. Increase user engagement: The primary goal of the "Products You May Wanna Buy" feature should be to increase user engagement with the Marketplace and drive more traffic to it. This can be achieved by showing personalized product recommendations based on user preferences and browsing history. 2. Improve product discovery: The feature should improve the overall product discovery experience for users. It should help users find products that match their interests and preferences, even if they are not actively looking for them. 3. Drive sales and revenue: The feature should drive more sales and revenue for Marketplace sellers. By showcasing products to users who may not have otherwise discovered them, the feature can increase sales for sellers. To decide how to build this feature, user research and data analysis are critical. The product team should conduct user interviews and surveys to understand user preferences and pain points around product discovery. They should also analyze user browsing and purchase data to identify patterns and trends that can inform the product's design. Once the team has a clear understanding of user needs and preferences, they can start prototyping and testing different versions of the "Products You May Wanna Buy" feature. The team should use A/B testing to compare the performance of different versions and iterate based on user feedback and data analysis. In summary, building a successful "Products You May Wanna Buy" feature on the Newsfeed requires setting clear goals, conducting user research, and using data analysis to inform the product's design. With a user-centered approach and a focus on driving engagement, product discovery, and revenue, this feature can be a valuable addition to Facebook Marketplace.
