Let’s play a little A/B test game. If I show you two versions of a headline, can you guess which one had better results?
From my tests, the headline that states a concrete outcome with a number wins about 7/10 times, but only when the subhead echoes that outcome. Since you’re showing “two versions of a headline,” freeze the image/CTA and keep the first line under 12 words to isolate the effect. @OP, did you pit a number-plus-benefit against a clever question, and if so, what was mobile’s split?
