WhichTestWon's Analysis: (Click back to see versions A & B)
The entire test series – which over time pitted four differently worded privacy policies against a no-policy control – ran in four stages over 48 days. The testing team had originally only tried Version A against the control as a proof of concept test, to show the executive in charge that privacy policies are important. When that initial test tanked, the team kept at it, trying different policy wording until they found a winner (Version B here.) We applaud their tenacity.
