# How does OPTIS Combined Listings work?

OPTIS lets you show **separate Shopify products as one listing** with swatch options - without merging or deleting any products.

### The idea in one picture

### Step by step

1. You **create a group** (manually, by a rule, in bulk, or by splitting a product).
2. OPTIS publishes that group to your storefront through its **app embed**.
3. On the product (and optionally collection) page, shoppers see a **swatch selector**.
4. Clicking a swatch **opens the matching product** - with its own images, price, and URL.

### What it does *not* do

* It does **not** merge products into one - each stays a real, separate product.
* It does **not** change your prices, SKUs, or inventory.
* It does **not** delete anything when you remove a group; only the grouping goes away.

Because each product keeps its own page and URL, your SEO is preserved. See [Does combining products hurt my SEO?](/optis-combined-listings/frequently-asked-questions/seo-and-urls.md)
