Our themes use product tags as "upsell tags" to set up upsell. An upsell tag must be a handle string(only allow letters, "-", "_", no space, no special characters) and have the syntax: "upsell_". Refer to here for more details about the handle string. When users view a product page, products have at least one upsell tag that is identical to the current viewing product's upsell tags will be displayed as upsell products. A product is able to have many upsell tags.

Example: product A has the upsell tags are upsell_fashion, upsell_clothing. When users view this product on the product page. Products have tags upsell_fashion or upsell_clothing will be shown as upsell products.

Upsell products are also shown in the popup cart after a product has been added to the cart.
