Check 10 / 21 LOW impact In the full checklist
Color / size swatches with photos, not dropdowns
What this check is
A dropdown hides the colour; a swatch shows it. On a product where colour or pattern is the reason to buy, a picture of each variant in the selector reduces both the wrong-variant order and the hesitation.
How to implement it
Map each variant to an image, enable swatches in the theme, and use the real product photo for each colour rather than a generic paint chip. On mobile keep the swatches large enough to tap without zooming.
How to verify it
Tap through every swatch on the product page and confirm the main image, the variant price and the URL update, and that an out-of-stock variant is visibly disabled rather than silently selected.
