Upselling with tags
Broadcast includes a 'Goes with' feature to help upsell products on individual product pages
This article is for Broadcast v3.0 to v3.3.1 only. Tags are not supported as of v3.4
With Broadcast, you can suggest a pairing product on any of your Product pages. This allows the customer to purchase two separate products within one product page.
Two upsell opportunities
One - Broadcast can suggest a product to pair with. The customer can choose the upsell product from the Cart after adding the primary product.

Two - Customer can add the upsell product to the Cart directly from the main product page and also add the primary product to Cart.

How to:
There are two steps involved with setting up upselling:
Add the Upsell theme block to the default product template
Tag your product with a custom upsell tag to pair/link with another product
1. Add the Upsell theme block to the default product template

Position the upsell promotion
Use drag-and-drop to position the upsell theme block on your product page:

2. Tag your product with a custom upsell tag to pair with another product
To pair a product with another, you simply add a tag to the main product with a custom tag. The tag links to the upsell product or links directly to a variant of the upsell product.
Here's an example of a primary product called 'Ilona Signet Ring in Sterling Silver'. We'll add the custom upsell tag here. This tells Broadcast that when a customer is viewing the 'Ilona Signet Ring in Sterling Silver' product page, a separate product can be suggested as an upsell. The upsell product is the custom tag (Ilona ring in gold):

We simply add a tag called '_upsell_ilona-ring-in-gold' to 'Ilona Signet Ring in Sterling Silver', which implies that 'Ilona ring in gold' is the product we want to promote on the 'Ilona Signet Ring in Sterling Silver' page.
Creating upsell tags
There are three parts to creating your custom upsell tags:
The first part of the tag must start with
_upsell_The second part of the tag must match the product handle of the upsell item
The last part is the variant ID. This is only required for products with variants.
Example of a completed tag without variants: _upsell_ilona-ring-in-gold
Variants
Broadcast can suggest more than just an upsell product. Broadcast can suggest an exact variant of a product to upsell. This can be helpful if you're trying to upsell a certain color or size of the product.
Example of a completed tag for a product that has variants: _upsell_ilona-ring-in-sterling-silver_40854006726691
Finding the product handle
All Shopify products have a unique product handle. You can easily find the product handle in the main Shopify Admin under Products. Choose any product in your Shopify Admin for Products, then simply use the 'Edit' link to view details about that product, including the handle:

Finding the product variant ID
All Shopify products with variants have a unique ID number associated with the product.
To find the variant ID, browse the product in your Shopify Product Admin, choose the Edit button next to the desired variant, and find the variant ID at the end of your browser URL address:

Remember, only products with one or more variants require the variant ID in the upsell tag. If your product has no variants (like our Ilona ring in gold example) you only need the prefix and handle.
Cart upsell promotions are only supported when Cart Drawer is enabled in the Theme Settings.
Changing the 'Complete the look' heading
The main heading for this block uses a translatable string:

To change this heading you can go into your Online Store -> Edit default theme content:

In the Products tab edit the 'Upsell title' field:

Save the changes and check your Product pages:
