Your Cross-Sell Isn't Failing Because of the Products. It's the Timing
Most A/B tests on cross-sells focus on which products to recommend. That's the wrong variable. After running hundreds of cross-sell tests, the clearest finding is that

What's inside
What you get
the mechanism: timing, framing and placement,
matters more than the merchandise.
Same products, wrong moment: 3% attachment rate. Same products, right moment: double digits.
These are the patterns I see almost everywhere:
\- Cross-sell fires the instant someone clicks Add to Cart
\- Copy that says "customers also bought" instead of completing the decision
\- Three products shown when one would perform better
\- Mobile and desktop treated as the same context
What's actually happening at the add-to-cart moment isn't decision paralysis.
It's a committed, forward-oriented buying state.
The cross-sell that works isn't the one that rescues an overwhelmed customer, it's the one that gives their momentum somewhere to go.
I put together a document that walks through the psychology behind this, the placement patterns we've tested across 4,000+ tests and €500M+ in client revenue,
and what a high-performing cross-sell implementation actually looks like.
\- The psychology behind why timing matters more than product selection - What "search momentum" is and how to use it
\- The placement patterns that consistently move ARPU
