Messaging mismatch between ad and landing page
US buyers — especially at higher CAC levels — are fast to dismiss pages that don't immediately confirm they're in the right place. When the ad copy speaks to a specific pain, feature, or offer, and the landing page opens with a generic value proposition, the signal is that the page wasn't built for them. Message match between ad and page is the first thing we audit because it determines whether anything else on the page even gets read.
