What types of tests will someone in e-commerce frequently run?

• A. Ad copy tests, landing page tests, and video creative tests
• B. Price tests, color tests, and font tests
• C. Mobile responsiveness tests only
• D. Email subject line tests only

Answer: (A)

In e-commerce, testing focuses on the assets that drive how users first respond to your offers and how they convert. Ad copy tests reveal which messaging, benefits, and calls to action resonate and push people to click. Landing page tests compare different layouts, headlines, hero images, and social proof to maximize the chance a visitor becomes a buyer. Video creative tests evaluate which video variants best communicate value and keep viewers engaged long enough to act, often boosting both engagement and conversions across ads and landing pages. Together, these areas cover the main points where marketing assets influence the customer journey from initial interest to purchase.

Other options can play a role in specific situations—price, color, and font tests can be useful, but they’re not as universally central to ongoing e-commerce experimentation as ad copy, landing pages, and video creative. Mobile responsiveness is essential, yet it’s a single aspect of the site experience, and email subject lines pertain to email campaigns rather than the broader testing you’d typically do across ads and the site.
