In Salesforce Commerce Cloud, there are several common reasons why products might not appear in the storefront. Two significant factors include:

Product lacks a price: Products without a set price are generally not displayed in the storefront because they cannot be purchased, which makes them irrelevant to the customer shopping experience.

Product is not online: If a product's online status is set to false, it will not appear in the storefront. This status is typically used to control the visibility of products directly from the catalog management within the Business Manager.

Products set to "searchable" or lacking images might still appear in the storefront, although they might not be as effective in attracting customer interest. The "Available to sell is <1" typically does not hide the product but may indicate that it is out of stock.
