Catalog evaluation is a special diagnostic view inside PrestaShop that scores quality, completeness, and health of your product pages. Think of it like a report card or an automated inspector that looks at every item listed on your digital shelves and checks if you did a good job filling out information.

When you manage hundreds of products, it is easy to forget things. You might create a product page but forget to upload a photo, leave description blank, or forget to add stock numbers. This tool scans your entire inventory list and highlights exactly where information is missing. It points out which products are invisible to public, which ones lack images, and which ones need better descriptions.

Having a fully completed list is incredibly important for two reasons. First, customers will not buy an item if page has no description or image. Second, Google ignores pages that have empty text blocks. This assessment tool guides you straight to weak spots in your store, telling you exactly what needs to be written or uploaded next to make your store look professional and easy to find.
