When viewers sense a hidden layer, they pause and interact; that tiny moment of engagement increases memory and sharing.

Good digital pop-ups do not attempt to deceive the viewer with illusory affordances. They offer a clear visual clue that something will be different when swiped or tapped. That clue is the invitation, and the disclosure is the payoff.
