If you use the EliteAI features Fallback, SmartExtend or SmartMatch, EilteAI may show products that you have not explicitly set in your upsell flows.
Most stores don't need to exclude products, but here are a few reasons you might want to exclude products. These are often related to the usage of other apps, e.g. wholesale apps.
B2B-only products
Bundles that the customer needs to first configure through a bundle app
Products that handle customizations
EliteCart automatically excludes:
products you have selected as 1-Click Addons.
products that are not available (e.g. sold out, in draft or archived, not published to online store channel...)
products that are already in the customer's cart.
If you wish to exclude additional products from being suggested as upsells by EliteAI, you can do so by adding a specific tag to those products. Here's how:
In your Shopify admin, go to Products and select the product you want to exclude from EliteAI upsell recommendations.
In the Tags area, add the tag _elite_ai_exclude.
Save the product.
If you wish to use your own tags, e.g. because you already have a "b2b" tag assigned to those products you wish to exclude, you can add those in the EliteAI settings:

By adding the _elite_ai_exclude or any of your defined tags to a product, you are instructing EliteAI to never suggest that product as an upsell, regardless of the items in the customer's cart.
Another option to hide products from ever showing us upsells is to use a custom metafield. You can read more about in this article:

Optionally hide products via metafields
The tag and metafield methods above hide products everywhere. If you'd rather control which products EliteAI™ Ultra can recommend on a specific location, you can build a fine-tuned version of Ultra and add a filter. For example, "only recommend products in a certain collection", or "never recommend products tagged b2b". Filters apply only to the location you assign that version to, so you can be selective without affecting the rest of your store.
This is an advanced, optional feature. For most stores the tag method above is the simplest way to exclude products. To learn more, see this article:
