A product catalog is a type of marketing collateral that lists essential product details that help buyers make a purchase decision. These details include product features, descriptions, dimensions, price, weight, availability, color, customer reviews, and more. The best example of a product catalog is the Amazon marketplace, where you can get a host of information in a single click. Think about a book that you’ve been trying to buy – Amazon lists all the information that you need. It includes the book title, author name, publisher’s name, number of pages, a brief snapshot of the book, price, dimensions, offers/discounts, reviews, and more.
