Before
After
IF we make the mobile filter button sticky, THEN users will be more likely to use filters and find relevant products, BECAUSE keeping the filter button accessible throughout the scroll improves usability and navigation.
A sticky filter button was implemented on mobile collection pages, positioned at the bottom of the viewport. The button opened the existing filter panel and was styled to be clear and non-intrusive while remaining accessible during scrolling.

Change in amount of clicks
The sticky mobile filter button led to a steep -16.0% conversion rate drop and -6.74% revenue decline despite a strong +11.6% AOV increase. While the persistent filter access may have encouraged users to refine their searches more aggressively—potentially narrowing options too much—the higher AOV suggests those who did purchase were finding more relevant, higher-priced products. The -4.2% add-to-cart decline indicates the sticky element may have disrupted the natural browsing flow on mobile rather than enhancing it.
