Make sure that all of the following criteria are met:
the site has at least one page with a list of product offers (for example, http://www.allcomputers.com/computer-accessories/external-hard-drives)
the content with the product list is static, and is not loaded automatically to the page (for example, as a script). Products must be present in the page's HTML code with the list of product offerings;
every product in the list of product offerings has a name and a link to a separate page with a detailed description.
