Variations (also known as parent-child relationships) are sets of products that are related to one another. Good variation relationship listings allow customers to compare and choose products based on different attributes such as size, color, or other characteristics from the available options on a single product detail page.
Not every category supports parent-child relationships, and not every variation is appropriate for a parent-child relationship. If an appropriate variation theme exists for your products, you must include your products in a parent-child relationship.
Parent-child relationships help to make search results manageable for customers. For example, you might offer a shirt that comes in four colors and four sizes. Rather than display all 16 unique combinations of the product in search results, only the one product from the parent-child grouping appears. The specific product that appears depends on the category.
The images displayed on a variation detail page will behave depending on the dimensions available for a buyer to choose from. Dimensions are the options given to the customer to choose the right product variant, for example size, color or style.
In a variation we can find two types of dimensions:
The Clothing, Accessories & Luggage, Sporting Goods, and Beauty categories display the parent products on product detail pages. This means that display elements such as product title and description appear from the data associated with the parent product.
Before customers can buy the product, they must first use the drop-down menus on the product detail page to indicate which child product they want to buy. Selecting options from the drop-down menus does not load a new product detail page.
For example, in Clothing, when customers look for a t-shirt, the parent product appears:
All other categories display only the best-selling child product in search results and on product detail pages. Display elements such as product title and price appear from the data associated with the best-selling child product.
Clicking the product loads the product detail page for the best-selling child product. From this page, customers can view other child products from the same grouping using a drop-down menu or product images.
For example, Candies come in different sizes. In the search results below, one variety appears because that is the best-selling child product among the other size variations:
Clicking one listing opens the product detail page, which offers other products in the same variation. After making a selection, the customer buys the product.
