What's the difference between a Conversion Block and a section?

Blocks and catalog sections are separate products, even with the same name. Learn how to tell them apart and which settings belong to which.

Updated November 4, 2026

A Conversion Block is a small piece that sits inside a section, usually your product buy box. A section is a full part of a page from our Sections catalog. They are separate products with separate settings, even when they share a name.

Settings that belong to sections, not blocks

If a guide names one of these, it is about a catalog section. The block doesn't have it.

  • Addons Position, Form Class and a Custom Liquid <div id="ss-addons"> are for add-on sections. The Addons block has none of them. It finds your product form by itself.
  • Year, month, day and hour fields and UTC are for countdown sections. The Countdown timer block has none of them.

How to check what you have

  1. In Shopify admin, open Online Store → Themes.
  2. Click Customize on your theme.
  3. Open the product template and look in the left sidebar.

An item nested under Product information is a block. An item on its own level, like SS - Product Addons #2, is a section.
