About Sticky Add to Cart for Shopify

Seny's Sticky Add to Cart app gives Shopify merchants a production-ready widget for product pages after the primary purchase section scrolls away. It is designed to feel native to the storefront: clean typography, responsive spacing, brand controls, and conversion-focused states are built in. Start from the ready-made app, describe changes in plain English, adjust the visual details, and publish through an Online Store 2.0 app embed without adding theme snippets or maintaining another single-purpose app.

What merchants use Sticky Add to Cart for

High-intent use cases for this Shopify storefront app, from product-page conversion to cart and campaign moments.

  • Add Sticky Add to Cart where it matters

    Place the widget on product pages after the primary purchase section scrolls away, with copy and behavior tuned to the exact buying moment.

  • Match your storefront design

    Control colors, spacing, copy, rounded corners, images, and layout so the widget feels like part of the same store.

  • Lift conversion without extra theme work

    Use AI prompts or visual controls to create seasonal, product-specific, and promotion-specific versions quickly.

Sticky Add to Cart app vs custom Shopify theme code

A custom section can work for one version of Sticky Add to Cart, but an app embed is better when you need repeatable campaigns, easy editing, and a consistent library of conversion widgets.
