FAQs
Which format should I A/B test?
Test inline vs popup for highest impact. Popup is industry default. Inline often wins for high-AOV apparel because customers don't have to click to verify.
Multiple formats per product?
Yes. Tailor Size Guide allows per-product layout override. High-AOV items: inline. Standard items: popup. Test 50/50 split, measure conversion.
