A developer has made some changes to the products of an existing storefront, but they...

The developer forgot to publish the storefront after making changes to the products. Publishing the storefront is a necessary step to make the changes visible to the store visitors. Publishing the storefront updates the site’s metadata and content, and also triggers the site index and search index rebuilds. If the developer does not publish the storefront, the changes will not be reflected on the live site.

The following actions are not required or relevant for the scenario:

Activate the product list. This action is only needed when creating a new product list or modifying an existing one. It does not affect the visibility of the products on the storefront.

Rebuild the search index. This action is automatically performed when the developer publishes the storefront. It is not a separate step that the developer needs to takemanually.

Publish the catalog. This action is not applicable for Salesforce B2B Commerce for Visualforce, which does not use catalogs. Catalogs are only used by Salesforce B2B Commerce for Lightning Experience.
