How to add products comparison to the website

The comparison allows you to compare several products of the same category, generating a final table with a list of these properties and characteristics. This feature is especially important for household and electrical equipment stores, as well as other products with a large set of technical properties and parameters:

The comparison table in the example above displays both all the characteristics and only those that are different, so that it is easier to compare the product for each criterion.

It's also important that there is quick access to the conversion buttons in the comparison block that allows you to buy goods. Thanks to the comparison feature, the client can make his/her choice on which product to buy without addressing an assistant for help, which simplifies the website usability.

Without the comparison feature, it's more difficult for users to navigate across the variety of products and understand how the price of a particular product is formed. Often the products of one group differ in price only because of several technical characteristics that are best seen when comparing on one page.

As a rule, CMS online stores already have built-in solutions that allow you to compare products; however, the modules expand the functionality and make use of comparative tables more convenient.

• use ajax technology when removing goods from the list, so to avoid page reloading;
• use the slider in the product table;
• quickly delete all selected products in the table by clicking "Clear All".
  

The example shows changes in the implementation of the comparison feature: it displays the chosen categories, buttons to enable viewing only differences and removing all products from the table. Additional features and a product slider are also visible:
