As a product data scientist at Airbnb, measuring guest experience throughout the user flow is important to understand how well the platform is serving its customers. Here are some metrics that Airbnb might use to measure guest experience at each step of the user flow: 1. Search: - Search result relevance: Airbnb could measure how often a guest clicks on a search result and books a stay, indicating that the search results were relevant to the guest's needs. - Search result diversity: Airbnb could measure how often a guest clicks on multiple search results before booking, indicating that there is a diverse selection of listings that meet the guest's needs. - Search time: Airbnb could measure how long it takes for a guest to find a suitable listing, with a shorter search time indicating a more positive experience. 2. Booking: - Conversion rate: Airbnb could measure the percentage of guests who complete the booking process, indicating how easy and intuitive the booking process is. - Booking abandonment rate: Airbnb could measure the percentage of guests who begin the booking process but do not complete it, indicating potential pain points in the process that need to be addressed. - Booking confirmation time: Airbnb could measure how long it takes for a guest to receive a booking confirmation, with a shorter confirmation time indicating a more positive experience. 3. Stay: - Review ratings: Airbnb allows guests to leave ratings and reviews after their stay. Airbnb could track the average rating and the number of positive reviews to measure guest satisfaction. - Response time: Airbnb could measure how quickly hosts respond to guest inquiries and requests during the stay. A fast response time could indicate a positive guest experience. - Length of stay: Airbnb could measure how long guests stay in a listing. A longer length of stay could indicate that guests are having a positive experience and are satisfied with the listing. 4. Post-stay: - Repeat bookings: Airbnb could track how many guests return to book another stay on the platform. Repeat bookings could indicate that guests had a positive experience and are likely to return. - Net Promoter Score (NPS): Airbnb could use the NPS metric to measure how likely guests are to recommend the platform to others. A high NPS score would indicate a positive guest experience. - Guest retention rate: Airbnb could measure how many guests return to book another stay on the platform. A high guest retention rate would indicate that guests had a positive experience and are likely to return. Overall, there are many different metrics that Airbnb could use to measure guest experience at each step of the user flow. The key is to identify the metrics that are most relevant to the platform's goals and to track them consistently over time to identify trends and areas for improvement.
