Cross-sells work best when the suggestion is genuinely complementary and shown after the main decision is made. Interrupting the purchase to suggest something else lowers the primary conversion, which usually costs more than the attachment earns.

Frequently asked questions
What is attach rate?
The share of orders that include a cross-sold item. Raising it a few points across all orders is worth more than a large improvement on a small subset.
Where should cross-sells appear?
Cart page and post-purchase work well. Product page cross-sells can distract from the main decision, though 'frequently bought together' blocks are a well-tested exception.
What makes a good cross-sell?
Genuine complementarity and a low price relative to the main item. Recommending an alternative rather than an addition creates doubt about the choice already made.
Are automated recommendations worth it?
At scale, yes — they outperform manual curation once there is enough behavioural data. Below a few thousand orders, hand-picked pairings usually do better.
