What it was
The SRP filter bar scrolled out of view once users moved past the first few listings, requiring them to scroll back to the top to refine. The hypothesis was that a sticky filter bar — fixed below the header during scroll — would reduce refinement friction and increase the share of sessions that applied at least one filter, with a downstream effect on contact rate. The test ran on 50% of authenticated SRP sessions on desktop web.
What we learned
Learning
Sticky filter bar increased filter application rate by +4.2% (95% CI: +2.1% to +6.3%, reliability 0.96). Dealer contact rate increased +1.9% (CI: +0.4% to +3.4%, reliability 0.93). SRP bounce rate dropped 0.6% — flat within noise. Effect was stronger on desktop than on smaller viewport sizes. Decision pending sign-off from Search engineering on the layout impact to ads placements.
