A campaign might attract lots of attention because creative, targeting, or incentives are broad, but that traffic may be low-intent or unfamiliar with the brand, so they don't convert when they reach branded search or site. Tracking user paths shows where curiosity fades, like landing pages that entertain but don't persuade. Engagement metrics act like heatmaps of interest, but conversion drop reveals mismatch between message and intent. Comparing branded search volume and assisted conversions helps spot leakage. Over time, refining targeting and aligning ad promises with landing experience improves efficiency overall performance.
