The difference between an online store that converts and one that merely survives often comes down to what happens after a customer decides to buy. That moment of commitment opens a brief window where the right suggestion feels helpful rather than pushy, where complementary products or upgraded version of that original product actually solves a problem the shopper wasn't consciously aware they had.
But the language around those techniques can feel like alphabet soup. AOV, ARPU, cross-sells, down-sells, one-click offers, post-purchase funnels. Each term represents a specific lever Shopify Merchants can pull to boost revenue and CLTV without spending another dollar on acquisition.
So we designed this glossary to cut through even our own jargon. Whether you're building your first upsell campaign or optimizing a sophisticated post-checkout flow, you'll find clear definitions for the terminology that matters to you. No marketing fluff, no unnecessary complexity. Just all the concepts you need to understand what's possible and how to make it work for your store.
