How It Works

The Upstack Pixel detects pinch-to-zoom gestures on touch devices. While zooming on product images is a positive engagement signal, excessive zooming on text or UI may indicate the content is too small or images lack detail.

When to Use

Scenario	Action
High zooms on product images	Provide native image zoom functionality
High zooms on text content	Increase font size or improve mobile layout
Comparing product categories	Identify which products need better imagery
Mobile UX audit	Ensure content is legible at default zoom

Metric	Relationship
Avg. Swipes	Another mobile gesture
Avg. Interactions	Total interaction events
Intent Score	Zooming on products may indicate intent
