Cross-selling in the webshop – How to increase the value per order

Cross-selling is about making each order more valuable for both the customer and the webshop by suggesting thoughtful, relevant add-ons that complement the main product. The article describes how a clear strategy, intentional placements in the customer journey, and ongoing conversion optimization can elevate cross-selling from random related products to a concrete growth engine that is perceived as genuine assistance rather than hard selling.

Cross-selling - How to Increase Value Per Order

Cross-selling sounds simple, and it is. The challenge is that many webshops place related products randomly and hope that the customer will find the logic on their own. This rarely happens. Cross-selling works best when it feels like assistance and when it clearly makes the main product more useful, complete, or easier to get started with.

Cross-selling in the webshop

Cross-selling in a webshop is about suggesting a relevant add-on that makes the customer's purchase more complete. It's not about having more products at any cost, but about providing more value for the customer. A good cross-sell typically answers a practical question: What does the customer need to get full value from what they are already buying?

To make cross-selling work effectively, you often need to incorporate it into multiple touchpoints. This can be on the product page, in the cart, and after purchase, where the need for accessories or upgrades may be most apparent. If you want to seriously work on the entire customer journey, it makes sense to start with UX design, because placement, timing, and friction matter more than the recommendation itself.

Cross-selling strategy

It is often said that more data solves cross-selling. Data helps, but what truly creates impact is direction. A cross-selling strategy is an agreement with yourself about when you recommend what, and why you do it.

You can start with three simple decisions that make recommendations more relevant and easier to manage over time:

  • Which product pairs make the most sense for the customer, and not just for you?
  • What placements are most natural in your flow, for example, product page, cart, and checkout?
  • What goals are you aiming for, such as a higher average order value or more products per order?

Once the strategy is set, it becomes easier to test and improve without creating noise in the store. You know what you are trying to achieve, and you can more clearly assess whether a change actually helps the customer and improves performance.

Product recommendations on Shopify

Shopify makes it relatively easy to get started with product recommendations. The challenge is that easy often ends up being standard. Standard rarely fits perfectly with your assortment, your margins, and the way your customers typically shop.

When standard is not enough

If you need more control, you can work with a customized setup where recommendations take into account stock levels, categories, or specific combinations. This is typically where platform activation in Shopify and possibly custom applications becomes relevant because you can build logic that matches your business and the way customers shop.

Upselling and cross-selling

Upselling and cross-selling are often confused, but they serve two different purposes. Upselling is when you try to get the customer to choose a more expensive version of the same product. Cross-selling is when you suggest something that complements the purchase and makes it more complete.

Both can work if it is clear to the customer what they will get out of it. If the customer has to guess, they will click away. If you want to find out what actually works in your store, you conversion rate optimization (CRO)relevant, because it is about continuous improvements and not a one-time project.

Conversion optimization of cross-selling

Cross-selling is not a widget you check off on a to-do list. It is a discipline that needs to be adjusted as the assortment, behavior, and campaigns change. Therefore, it is important to work in a structured way and test in small steps, so you learn quickly and avoid making the experience more disruptive for the customer.

A practical way to get started is to choose one location, one type of recommendation, and one KPI. Build from there as you gain insights.

Getting cross-selling to work consistently usually means thinking it into several touchpoints. That could be on the product page, in the cart, and post-purchase, where the need for accessories or an upgrade tends to be most obvious. Placement, timing, and friction often matter more than the recommendation itself.

A cross-selling strategy is essentially a set of decisions you commit to: when to recommend something, what to recommend, and why. You can start with three straightforward choices: which product pairings create the most value for the customer, which placements fit most naturally into your flow, and which goals you are working toward, such as a higher average order value or more items per order. Once the strategy is in place, it becomes much easier to test and improve without creating noise in the store.

Shopify makes it relatively easy to get started with product recommendations. The challenge is that easy often leads to default, and default rarely fits your specific product range, your margins, or the way your customers actually shop.
