Page test preferences
Choose which website tests you take part in. Your analytics choice stays separate.
First-party test cookies remember your assigned version for 30 days, separately from analytics cookies. Turning a test off removes its assignment and saves your choice for one year. Shopping and booking stay available.
How your preferences are used
The test cookies hold a random identifier and your assigned version to keep each test consistent. Declining analytics cookies does not reset your assigned version.
The delivery test applies to UK shopping in pounds. Switching it off restores the standard UK delivery threshold. Delivery eligibility is checked again at checkout.
The website tracking check compares two identical versions to check that our testing works. Its assignment applies across countries. Measurement still follows your analytics choice.
Analytics and outcome tracking require your separate analytics permission. Switching a test on does not grant that permission.
