On a phone, a product page is long: photos, description, specifications, reviews. By the time shoppers are convinced, the Add to cart button is far above. Some scroll back up; many do not.
What a sticky add to cart bar does
It shows a slim bar, at the bottom or top of the screen, as soon as the real Add to cart button leaves the view. The bar repeats the essentials: product photo, name, price and the button.
What to look for
- Appears only when needed, not on top of the real button.
- Handles variable products: it follows the chosen variation, or brings the shopper back to the options if none is selected.
- Uses the real WooCommerce form, so validation and AJAX add to cart keep working.
- Respects mobile details: the iPhone home bar area and reduced-motion settings.
- Light: it should not slow down your product pages.
Setting it up
Install Stickyline, choose bottom or top, phones and/or desktop, light or dark, and your button colour. Then open a product page on your phone and scroll. You can try it on the live demo.
Measure the effect
Compare your mobile add-to-cart rate before and after over a few weeks, with similar traffic. Every store is different, so your own numbers are the ones that matter.
