Every ecommerce operator knows the math: it costs nearly the same to acquire a customer who spends $50 as one who spends $150. That's why increasing average order value (AOV) is one of the highest-leverage activities in ecommerce. And personalized product recommendations are the most effective way to do it.
Why Generic Recommendations Fail
Most ecommerce stores use the same recommendation widgets: "Customers also bought," "You might also like," "Bestsellers." These are better than nothing, but they're fundamentally limited because they're based on aggregate behavior, not individual preferences.
A customer with oily, acne-prone skin sees the same "popular products" as someone with dry, mature skin. That's not personalization—it's just popularity.
The Generic Rec Problem: "Customers who bought this also bought..." recommendations have an average click-through rate of just 2-3%. Personalized recommendations based on zero-party data see 15-25% CTR.
The Personalized Recommendation Playbook
Here are the specific strategies top brands use to increase AOV with personalized recommendations:
Use quiz answers to recommend complete routines or bundles instead of single products. A customer who says they want to "build a full skincare routine" is primed to buy 4-5 products, not just one.
Use quiz responses to power cross-sells throughout the customer journey. If someone indicated they have "sensitive skin" in the quiz, show them gentle, fragrance-free options in cart cross-sells—not just bestsellers.
Sync quiz data to Klaviyo and use it to personalize product recommendations in every email. Instead of showing the same "Shop Now" products to everyone, show products matched to their quiz responses.
Show customers Good/Better/Best options at different price points. This anchors value and often leads customers to choose the middle or premium tier.
Use quiz data to identify subscription-ready customers. Someone who indicated they want a "consistent routine" or has "replenishment needs" is a great candidate for a subscribe-and-save offer.
