Magento Corssell and Upsells

Some time we get confused what is Crossell and Upsell. So let's understand the meaning and concept of the These two which are very important

An upsell is to get the customer to spend more money – buy a more expensive model of the same type of product, or add features / warranties that relate to the product in question.

A cross-sell is to get the customer to spend more money buy adding more products from other categories than the product being viewed or purchased.

More over they are confusing but let's take an example

I have Purchased the Nokia Mobile so here
Samsung Mobile == Upsell product
Micromax Mobile == Upsell product
LG Mobile == Upsell product

Nokia Headphone = Cross Sell
8 GB Memory Card = Cross Sell

So this is the only difference for upsell and Crossell

Hope it will helpful!
