Ask If a user barely notices a display ad but converts later, did the ad actually matter?

[Dean101]

Even if a user doesn't consciously register the ad, it can still plant a subtle impression that shapes later decisions. Tracking view-through conversions, time gaps between exposure and action, and multi-touch attribution helps reveal this hidden effect. Patterns like increased brand searches or higher engagement after exposure suggest the ad played a role. It's less about direct attention and more about cumulative influence. Over time, these small impressions can build familiarity and trust.
