Check 4 / 16 LOW impact In the full checklist
Collection filters as sidebar, not hidden drawer
What this check is
Filters buried behind a drawer icon get used far less than filters the shopper can see. A visible sidebar keeps size, colour and price within reach while the grid scrolls.
How to implement it
Switch the collection template to a sidebar filter layout on desktop, keeping the drawer for mobile where space is scarce, and order the facets by how shoppers actually narrow: availability, size, colour, price. Keep the selected filters visible as removable chips.
How to verify it
Apply three filters on desktop and confirm the sidebar stays in place while scrolling, the product count updates, and clearing a chip removes only that facet.
