The user has just added a pair of shoes to their cart. They pause for a moment, and a suggestion appears on the screen: “Add a waterproofing agent and a care brush – save 10%.”
This is no coincidence, but a well-thought-out cross-selling strategy that not only increases the value of the order, but also makes the customer feel that someone really understands their needs.
Another time, they see the message: “New model with better cushioning – only $15 more” – a classic example of up-selling, i.e., encouraging the customer to choose a higher-end product.
In the world of e-commerce, these subtle suggestions are like well-chosen recommendations from a salesperson in a brick-and-mortar store. When implemented properly, they can significantly increase sales and buyer satisfaction. For small online stores that cannot compete with giants in terms of advertising budget, cross-selling and up-selling are the easiest ways to increase revenue without acquiring new customers. All you need to do is offer an additional product at the right moment.
In this article, I will show you how to effectively implement these techniques in your store: from identifying opportunities, through practical implementation and personalization of offers, to tools (such as WebWave) that will help you do it wisely, ethically, and to the benefit of your customers.
What are cross-selling and upselling?
Up-selling is a technique in which you offer the customer a better, more expensive, or more advanced version of the product they are currently viewing. Instead of the basic model, you offer a premium version with additional features. Simple, but effective.
Cross-selling, on the other hand, involves offering products that complement the main purchase. The customer buys a hat, and you offer a scarf, gloves, and a brooch. This way, you increase the value of the shopping cart and make shopping easier for the customer.
Why should you implementing upselling and cross-selling in e-commerce?
Because sometimes you don't need more customers. You just need to make better use of the ones you already have. Cross-selling and up-selling allow you to offer them exactly what they need at the moment of purchase.
For small online stores, this is a smart way to increase sales without huge advertising budgets. Instead of fighting for new visitors, focus on getting each customer to buy a little more or better. This way, you not only build greater turnover, but also a relationship based on trust and a sense that you really understand the needs of your buyers.
How to identify opportunities for upselling and cross-selling?
Before you start making suggestions, it's a good idea to get to know your customer well. Review which products are most popular and what most often ends up in the shopping cart. That's where the opportunities for upselling and cross-selling lie. If someone buys coffee, a natural complement would be a grinder, milk frother, or cup. And if they choose an online course, you can offer an extended version with additional materials or expert consultation.
Trend analysis in your industry also works well. Check which products customers often combine, what improvements are attractive to them, and at what points they make their purchase decisions. It is worth creating logical purchase paths – ones that lead the customer from the basic version of the product or service to a more advanced one, tailored to their needs.
To make data-driven decisions, you don't have to invest in complex systems right away. Just connect Google Analytics, Meta Pixel, or other tools that track user behavior online. They will show you which pages bring the most traffic, which products are viewed together, and where customers abandon their purchases.
In the website builder WebWave, you can do this without any technical knowledge – you can connect all the necessary analytical tools from the webmaster level. You can easily check which offers really work and which need refinement – all so that every visit to your online store ends with a successful purchase.
Best practices for successful upselling and cross-selling
Properly applied sales techniques, such as upselling and cross-selling, can significantly improve results and strengthen brand loyalty. Find out how.
Practical upselling techniques
Upsell works best when you show the customer real benefits. It's not about aggressively promoting a more expensive product, but about helping them make a better choice.
Here are some proven methods:
-
Compare clearly – place two versions of the product side by side, e.g., “standard” and “premium.” Highlight what the customer gains by paying a few extra dollars.
-
Show value, not price – emphasize how the more expensive model saves time, is more durable, or more functional.
-
Use visuals – photos, short videos, feature icons – they work faster than text.
-
Suggest naturally – the message “Choose the PRO version to get an extra year of warranty” is more effective than “Buy the more expensive model.”
-
Introduce upgrades at key moments, e.g., in the shopping cart or just before finalizing the purchase.
Such actions not only increase the average cart value, but also give the customer the feeling that they are making an informed decision.
Effective cross-selling methods
Cross-sell is the art of combining products in a logical way. Is the customer buying a phone? Suggest a case, protective glass, or a power bank. This is a classic example of cross-selling that does not require much effort but can significantly increase profits.
Practical tips:
-
Combine complementary products – create sections such as “Frequently bought together” or “Customers who bought this product also chose...”.
-
Build bundles – offer a discount when purchasing a set, e.g., laptop + bag + mouse.
-
Use email marketing – after the transaction, remind customers about accessories or complementary services.
-
Personalize – tailor your suggestions to purchase history, season, or location.
-
Test the location of the offer – sometimes a section below the product description works better, other times a pop-up window in the shopping cart.
Pssst! You can easily create pop-ups with AI widgets in WebWave. Be sure to test them out!
Create your website, your way
Personalization and appropriate timing of offers
Personalization allows you to precisely target the user's needs and increase the likelihood that they will add an additional product to their shopping cart.
How to do this in practice?
-
Analyze user behavior – check what they have viewed, what they have purchased previously, and what products they have abandoned in their cart.
-
Create customer segments – e.g., new buyers, regular customers, premium users – and tailor your messages to their stage in the purchasing process.
-
Set rules for displaying offers – e.g., show a complementary product only when the customer adds something to their cart.
-
Use time and location data – offer an umbrella when rain is forecast, or a power bank during the festival season.
-
Be dynamic – smart recommendations can change in real time, responding to user actions.
The best results come from combining personalization with the right timing. When an offer appears exactly when the customer is looking for a solution, they don't perceive it as advertising, but as help.
User experience (UX)
Even the best-prepared cross-selling and up-selling in an online store will not be effective if the company's website is chaotic or overloaded with offers.
Keep it simple. Show a maximum of 2-3 additional product suggestions, and only those that really make sense in the context of the current purchase. Instead of overwhelming the user with options, use clean layouts, clear CTA buttons, and legible graphics.
It is also important that the messages are visually and linguistically consistent with the rest of the store. This makes the customer feel that it is a natural part of the purchasing process, rather than intrusive advertising.
In short, the simpler and more intuitive the purchasing process, the greater the chance that the customer will click “buy now” and come back for more.
Tools and integrations for small online stores
In the e-commerce industry, effective additional sales start with a well-prepared technological backend. Even the best cross-selling and up-selling strategies will not work without the right tools to support automation, analysis, and personalization of offers.
Here's what's worth investing in:
-
CRM system (e.g., HubSpot, Brevo, Klaviyo) – for collecting customer data, purchase history, and audience segmentation. This allows you to tailor your offer and the timing of additional sales.
-
Integrations with email marketing tools (e.g., MailerLite, GetResponse) – automate the sending of offers after purchase, e.g., with suggestions for complementary products.
-
Product recommendation plugins (e.g., Recom.ai, LimeSpot) – analyze user behavior and display dynamic upsell/cross-sell offers in real time.
-
Google Analytics 4 or Hotjar – help track user behavior, identify cart abandonment moments, and evaluate the effectiveness of specific offers.
-
Payment and checkout systems (e.g., Przelewy24, Stripe) – should be simple and fast so as not to discourage the customer from completing the purchase after adding a product from the additional offer.
During Black Friday, these tools are crucial: they allow you to automatically respond to increased traffic, personalize promotions, and monitor results in real time.
And if you use WebWave, you can implement all these integrations from the creator, without coding. This allows you to quickly launch campaigns, add email marketing modules, or pop-ups with additional sales offers. Ready for the biggest traffic of the year.
Measuring effectiveness and optimization
Without data analysis, even the best sales strategy is just guesswork. That is why regular monitoring of results is crucial in the e-commerce industry. Especially if you do both cross-selling and up-selling.
Keep track of the following in particular:
-
Average order value (AOV) – this shows whether your actions are actually increasing the value of the shopping cart.
-
Attachment rate – how often customers add matched products from recommendations.
-
Conversions from additional offers – these help you understand which messages, graphics, and layouts work best.
-
Time spent on the site and clicks on cross-sell/upsell sections – allow you to assess whether the offers are visible and attractive.
An example? If you offer a laptop and only 5% of buyers add a bag or mouse, it is worth testing a different product card layout, a more visible CTA button, or a better-chosen moment to display the offer.
Test different variants: the order of recommendations, the color of the button, the style of the message (“Get more for a little more” often works better than “Buy now”). Small changes can increase sales profits by several percent.
Legal and ethical aspects
Effective sales are not just about numbers – they are also about the customer experience and the trust you build with every interaction. When planning how to upsell or cross-sell, always prioritize transparency. Prices, discounts, and promotional terms must be clear from the first click, as hidden costs or misleading messages can quickly discourage a customer to purchase and harm your ecommerce business.
Protecting personal data is equally important. If you personalize offers, ensure it complies with GDPR and privacy regulations. Customers should understand why they see certain products and have the option to opt out of recommendations.
Ethical marketing is not a limitation, but a competitive advantage. Clear, respectful upsell or cross-sell offers enhance the customer experience, encourage repeat purchases, and build lasting relationships based on loyalty rather than one-time profit.

FAQ
What is upselling and cross-selling with example?
Upselling and cross-selling are two powerful ecommerce strategies designed to increase order value and enhance the customer purchase experience. Upsell means encouraging a buyer to choose a more premium or upgraded version of a product – for example, suggesting a laptop with more storage instead of the basic model. Cross-sell focuses on promoting related products, such as offering a laptop bag or mouse alongside the main item. When used together on the product page or during checkout, these techniques can significantly boost conversion rates and customer satisfaction.
What is the 25% rule of thumb for cross-selling?
The 25% rule suggests that your cross-selling techniques should not exceed roughly a quarter of the total value of the customer’s primary purchase. For instance, if a buyer orders a $200 camera, the related products you recommend – like a memory card or camera strap – should stay within the $50 range. This keeps the offer appealing without overwhelming the shopper or making the deal seem pushy. Following this rule helps maintain a positive customer purchase experience while still driving additional revenue.
What is upselling in e-commerce?
In ecommerce, upselling involves motivating customers to buy a higher-value version of the item they’re already considering. Effective upselling strategies often highlight better features, longer warranties, or bundled benefits to justify the higher price. For example, if a shopper adds basic headphones to their cart, showing them a wireless model with noise cancellation can lead to an upgrade. The key is to present the upsell naturally on the product page or during checkout, making it feel like a helpful suggestion rather than a sales push.
What is cross-selling in ecommerce?
Cross-selling in ecommerce means suggesting related products that complement what the customer is already buying, increasing both satisfaction and total order value. For example, if someone buys running shoes, offering socks, a sports bottle, or a smartwatch can create a more complete customer purchase experience. Successful cross-sell techniques rely on timing and relevance – presenting these add-ons at the right moment in the buyer journey. When done right, cross-selling strengthens brand trust and drives long-term customer loyalty.
