Differentiate Between UpSell & CrossSell Products

What is Cross-Selling?
Cross Sell Products are displaying shopping cart pages before checkout process

Cross-selling is a sales strategy to sell products that are different, but possibly related to a product your customer already has already added to cart. It offers customers the option to buy complementary products in addition to the main product they intended to purchase.

For example, if a customers are purchasing a mobile phone, Site Owner might want to suggest they purchase headphones or an additional charging cord along with their new phone.

In Magento 2 products that are offered as cross-sells appear on the shopping cart page just before your customer starts to check out. Think about how items such as candy, gum, and magazines are placed near the checkout in grocery stores. These are items that your customers may not have intended to buy while they were shopping, but these items enhance the shopping experience.

Up-selling is a sales technique where you suggest to your customer that they might prefer to buy a more expensive version of an item, to upgrade an item they already have, or to add features or other add-ons to an item.

For example, if a customer is browsing for a laptop on your site, and they are looking at a model with a 500gb hard drive, you might suggest an upsell of a larger (and therefore more expensive) hard drive.

In Magento 2 up-sells appear on a product page under a heading that might say something like “You May Be Interested In The Following Products”.
