--- title: Boost rules for product listing pages slug: o5sf4480 canonical_url: https://docs.coveo.com/en/o5sf4480/ collection: coveo-merchandising-hub source_format: adoc --- # Boost rules for product listing pages In the [Product listings manager](https://docs.coveo.com/en/p64e0262/) of the [Coveo Merchandising Hub (CMH)](https://docs.coveo.com/en/o5290573/), merchandisers can define _boost_ ranking rules to make products that match specific criteria appear higher on [product listing pages (PLPs)](https://docs.coveo.com/en/m1sf3187/). These rules are based on product attributes that are available in the [indexed](https://docs.coveo.com/en/204/) [metadata](https://docs.coveo.com/en/218/), such as brand, category, or price. Boost ranking rules can apply to all PLPs or to one or more specific PLPs. They can also be scheduled for a specific time, letting merchandisers plan and execute their strategies more effectively. ![Boost rule for product listing pages | Coveo](https://docs.coveo.com/en/assets/images/coveo-for-commerce/images/cmh/cmh-listings-boost-rule.png) ## Use case examples Boost ranking rules can be used to address a variety of use cases. Here are a few examples: * **Boost promoted products**: Raise the ranking of products that are part of a specific promotion. * **Feature specific brands**: Boost the ranking of products from specific brands in a given category page. * **Feature high-margin products**: Enhance the ranking of products with higher profit margins. * **Highlight new arrivals**: Increase the visibility of newly added products to the inventory. * **Boost high stock products**: Promote products that have a high inventory to encourage sales. ## Prerequisites Before you create rules in the [Coveo Merchandising Hub (CMH)](https://docs.coveo.com/en/o5290573/): * In the [Coveo Administration Console](https://docs.coveo.com/en/183/), [map](https://docs.coveo.com/en/217/) the [metadata](https://docs.coveo.com/en/218/) that you want to use as attributes in rules to the corresponding [fields](https://docs.coveo.com/en/200/). These [fields](https://docs.coveo.com/en/200/) must have the **Facet** or **Multi-value facet** option enabled. For example, to use the `color` [metadata](https://docs.coveo.com/en/218/) as an attribute in a rule, [map](https://docs.coveo.com/en/217/) it to a [field](https://docs.coveo.com/en/200/) with the **Facet** or **Multi-value facet** option enabled. * [Create query pipelines](https://docs.coveo.com/en/o48e0216#storefront-associations-and-query-pipelines). * [Choose the correct property](https://docs.coveo.com/en/o6lb0453#property-and-locale-selectors) to ensure that your changes affect the intended listing pages. ## Create boost rules To create boost rules .
