Clear direction and obvious value are the strongest predictors of ad success. Three clarity elements consistently boost engagement: explicit offers (+5.2% lift), clear call-to-action language (+2.9% lift), and prominent CTA buttons (+4.4% lift).
When combined, these elements create powerful synergy. The most successful ads in our dataset featured specific offers ("Claim Offer"), clear action words ("Buy Now”), and made these elements visually prominent with button design.
