- The importance of not being too aggressive
Acquiring a new customer costs 5 to 25 times more than keeping an existing one. That's why, if you have an e-commerce, your priority must be to maximize the value of every single transaction.
The difference between Cross-Selling and Up-Selling
- Up-Selling: Pushing the customer to buy a superior (more expensive) version of the product they are looking at. Example: Looking at an iPhone 15? I'll propose the iPhone 15 Pro.
- Cross-Selling: Proposing complementary or related products. Example: Have you put the iPhone in your cart? I'll propose the cover and the protective glass.
Where and when to propose the right offer
- On the product page: Show "Products often bought together".
- In the shopping cart (Mini-cart): One last offer before checkout ("You're only €10 away from free shipping, add this accessory").
- Post-purchase: A thank you email with a discount code valid only for the next 48 hours on a specific category.
Practical examples for local e-commerce
If you sell local products:
- The customer buys a wine? Do Cross-selling by proposing a package of artisanal taralli.
- The customer chooses a 0.75L bottle? Do Up-selling by proposing the Magnum with a 10% saving per liter.
The importance of not being too aggressive
The secret to success is relevance. If you propose socks to someone buying a drill, you destroy the customer's trust. The offer must feel like useful advice, not a desperate attempt to empty the warehouse.
