What Is a Sticky Add to Cart Button and Why It HelpsUpdated 2 months ago

A sticky add to cart button stays visible at the bottom of the screen as a buyer scrolls through a product page. On desktop, the add to cart button is usually reachable without much scrolling. On mobile — where the majority of Shopify traffic arrives — a buyer can scroll through images, descriptions and reviews without the button ever being in view.

When the button is not visible, the buyer has to scroll back up to find it. That interruption breaks the momentum of the purchase at exactly the moment they have finished reading and are ready to act.

Here is what a well-implemented sticky button includes:

• The product name and selected variant visible so the buyer confirms they are adding the right option
• Price displayed clearly so there is no last-second uncertainty
• The button itself large enough to tap accurately on a small screen without mis-tapping

The sticky add to cart button requires no content changes and no redesign. It simply keeps the most important action on the page in reach at all times — removing a moment of unnecessary friction from the path to purchase that costs a percentage of potential sales every single day it exists.
