Can cross-selling and upselling improve brand revenue?

Absolutely. Cross-selling and upselling increase the average order value, which has a direct impact on revenue without requiring more traffic. For example, showing complementary items on product or cart pages can nudge customers to build a more complete solution. Upselling to a higher-tier product or subscription also improves customer experience while lifting margins. The key is timing and relevance: recommendations should be context-aware and not disrupt the user journey.
