When to use this
If you need to exclude many products at once — for example, 100+ items that should never appear in your recommendation widgets — tags are the recommended approach. Tags scale beyond the manual exclusion limits available in individual widget settings, and you can manage them directly in Shopify Admin or through any third-party tagging app.
Available exclusion tags
Add any of these tags to a product in Shopify to control where it appears:
Tag | What it hides |
| Hides the product from all Boost-powered widgets — Search, Collections, and Recommendations. |
| Hides the product from Recommendation widgets only (Related products, Frequently Bought Together, Personalized, Trending, Bestsellers, Recently Purchased). The product still appears in Search and Collections. |
| Hides the product as a "bad match" — typically used to exclude low-quality results. |
| Hides the product as "out of scope" — typically used to exclude products that shouldn't surface in normal browsing. |
⚠️ Note: Tags are case-sensitive. Use the exact format shown above.
How to add a tag to a product
Tags are added in Shopify Admin, not in Boost. Once a product syncs with Boost, the tag is recognized automatically — no extra setup is required.
For step-by-step instructions, see Shopify's guide: Adding tags to a product.
You can also bulk-tag products using:
Shopify's bulk editor
Third-party tagging apps from the Shopify App Store
The Shopify Admin API
When tags take effect
After you add or remove a tag, the change takes effect once the product syncs with Boost. Sync timing depends on your Boost plan. For details on sync frequency and how to trigger a manual sync, see How to use the Sync features.
