Why a small flourish near a button lifts the click

An e-commerce checkout page added a subtle sparkle animation next to the “Complete order” button. Click-through on the button rose by fourteen percent, and time-to-click dropped by 1.2 seconds. The sparkle was eight pixels wide — small enough to avoid ad-schema suppression, large enough to trigger peripheral motion detection.

What everyone sees

Shoppers describe the button as “easy to find” without mentioning the animation. The sparkle operates below conscious notice for most users — it serves as a peripheral attractor that guides the gaze to the button zone without registering as a deliberate visual cue.

What is actually happening

Franconeri and Simons’s research on attentional capture by small transient changes showed that even minimal motion in the periphery can redirect fixation. Because the flourish is small and non-rectangular, it avoids the banner-shaped schema that triggers suppression (Benway and Lane). The result is a cue that captures attention through motion detection while remaining invisible to the learned ad filter.

Why it stays hidden

The flourish hides because it is tiny and decorative. Users process it as ambient interface polish rather than as a gaze-directing mechanism. Its effectiveness depends on being below the threshold of conscious detection — if it were large or flashing, it would trigger ad blindness and be suppressed.
