To complement established UX research, we conducted our own review of 50 ecommerce stores across fashion, beauty, furniture, home goods, outdoor gear, accessories, and online marketplaces. Rather than searching for a single "perfect" filtering experience, we wanted to understand how successful brands adapt filters to different catalog sizes, product complexity, and shopping journeys.
Each store was evaluated on both desktop and mobile using the same UX framework to ensure consistent comparisons. We scored nine core aspects of filter usability consistently across all 50 stores:
- Filter discoverability
- Multi-select support
- Applied filters
- Dynamic filtering
- Filter counts
- Price filtering
- Sticky filters
- Visual swatches
- Search within filters
Beyond these nine scored criteria, three additional patterns came up repeatedly while reviewing individual stores, ones that don't reduce cleanly to a yes-or-no per store, but that clearly separated the stronger implementations from the average ones: how filters are ordered within the panel, how mobile filtering previews results before a shopper commits, and how closely a store's filter set matches what shoppers in that specific category actually decide on. We've included all three as practices in this guide, but we're explicit throughout about which claims come from the full 50-store comparison and which come from specific examples we observed.
How we selected stores: We selected 50 established ecommerce stores across fashion, beauty, furniture, home goods, outdoor gear, accessories, and marketplaces, mixing Shopify-native brands with a small number of larger enterprise retailers to see whether filtering patterns held across platforms. The sample is directional, meant to surface recurring implementation patterns, rather than a statistically representative survey of all ecommerce stores.
