Upselling and cross-selling: increasing average order value
Acquiring a new customer costs more than selling a little more to an existing one. Here are the mechanics that actually work on an online store site.
Related products on the product page
A 'frequently bought together' block should suggest genuinely related items, not random products from the same category. A phone case works; random headphones don't always.
This block converts better placed next to the add-to-cart button rather than below the description, letting shoppers add both items in one action.
Ready-made bundles
Selling a pre-built bundle at a small discount versus buying items separately raises the average order value while also simplifying the choice for shoppers who don't want to assemble a combination themselves.
Bundles work especially well in categories with an obvious logic to pairing items: cosmetics, kids' products, kitchenware sets.
Free shipping thresholds
Free delivery above a certain amount is one of the most predictable ways to raise the average order — shoppers just short of the threshold often add another item purely to save on shipping.
Showing a 'N UZS left for free shipping' indicator right in the cart works better than mentioning the condition only on a separate delivery terms page.
Upselling at checkout
A small offer of a pricier version of the item or an extended warranty right before payment converts better than banners on other pages, because the customer has already decided to buy.
Don't overload the cart with offers: one or two relevant upsells work better than a long list of random products that distracts from completing the order.
