Extensive user feedback and relentless rounds of user experience lab testing have helped us implement many of these changes. We also test new features among a small percentage of live users as they use Google normally. In the last year alone, we made over 530 changes and ran over 58,000 experiments, all to see how these changes would affect real users.
