Is it possible to share content across pages on Squarespace?

Assume you need to duplicate a few pieces of copy and blocks on 3 different pages, so if I update it in 1 place, it automatically updates everywhere.

The Short Answer

Natively, Squarespace doesn't have a built-in "Shared Content" or global component feature for individual page blocks. Once you copy a block to another page, it becomes an independent duplicate.

However, depending on your setup, you have a few ways to tackle this:

Method 1: The Native Workaround (Summary Blocks)

If you're looking for a quick, zero-cost native hack:

1. Create a hidden Blog Page.

2. Add your content/copy as a blog post.

3. Use Summary Blocks on your target pages to pull and display that post.

The Catch: It’s slightly limited in layout and works best for text or simple media rather than complex forms or interactive blocks.

Method 2: The Direct Solution (Synced Blocks)

If you want a true, flexible "Edit Once, Update Everywhere" experience for any native Squarespace block (text, forms, newsletters, images, etc.):

You can use Synced Blocks.

It allows you to turn any block into a master reusable asset. Drop it across as many pages or blog posts as you want, and whenever you edit the master instance—whether it's tweaking copy or updating form storage - every single instance across your site updates automatically.
