25. BE CLEAR WHY
YOU NEED A USER’S
LOCATION
Users should always understand why you’re asking
for their location. Participants trying to book a hotel
in another city became confused when a travel site
detected their location and offered hotels in their
current city instead. Leave location fields blank by
default, and let users choose to populate them
through a clear call-to-action like “Find Near Me.”
Key Takeaway
Always make it clear why you need
a user’s location, and how the information
will influence their experience.
