SuperCoolKicks wants to see which landing page experience is best for users who have clicked the Cool Kicks sneaker ads. What best practice should they follow while they’re running this test?

When testing landing page experiences, it's crucial to isolate the variable you're testing. By keeping the content on the landing pages unchanged, SuperCoolKicks ensures that any observed differences in user behavior or performance metrics are attributable to the landing page experience itself, rather than variations in content. This allows for a clear and accurate assessment of which landing page design or layout performs best. Testing many landing pages simultaneously can dilute results and make it harder to pinpoint the impact of individual changes. Testing landing pages in every ad is unnecessary and adds complexity without improving the test's validity. Keeping landing pages generic would likely lead to poor performance and wouldn't provide valuable insights into optimal user experience.
