Which is an example of a headline change that could be tested?

• A. Switching to a completely different product
• B. Changing the color of the button
• C. Changing "Act now while supplies last" to "Huge Savings, Limited Time Offer"
• D. Testing a new payment method

Answer: (C)

Headline testing focuses on how the wording at the top of the page influences user behavior. The example given changes the actual copy of that top message from “Act now while supplies last” to “Huge Savings, Limited Time Offer,” which directly alters the headline text and the urgency/value framing it conveys. This kind of variation targets messaging and how users interpret the offer, which can shift engagement and conversions.

The other options involve changes to elements other than the headline: switching to a completely different product changes what the page is about; changing the color of the button is a UI cue change rather than headline text; testing a new payment method affects the checkout process, not the headline. In a test, you’d compare the performance of these two headlines to see which drives better metrics like click-through or conversion.
