What are redirect tests used for in A/B testing?

• A. To test different color schemes of a single page.
• B. To test separate webpages against each other, useful for complete redesigns or testing different landing pages.
• C. To measure user engagement on mobile devices only.
• D. To optimize email subject lines.

Answer: (B)

Redirect tests compare whole pages by sending users to different URLs. This approach lets you evaluate an entire page design and user flow, which is ideal when you want to test a complete redesign or alternate landing pages rather than just swapping out individual elements. By directing traffic to different URLs, you can see how the overall page performs in terms of conversions, engagement, and navigation.

Other options focus on smaller, on-page changes like color schemes, which are tested within the same page rather than via full-page redirects. Measuring engagement on mobile devices targets device-level analytics rather than testing different page designs. Optimizing email subject lines belongs to email marketing, not on-site redirect tests.
