How do I A/B test Looksy?
Split eligible traffic between a control experience and one defined Looksy variation, then compare a preselected primary metric. Use an experimentation tool that is compatible with your current Shopify setup.Define the test before it starts
Record:- the question and hypothesis;
- included products, traffic, and devices;
- control and treatment experiences;
- primary metric and guardrails;
- planned duration and stopping rule;
- exclusions and data-quality checks.
What can I test?
- whether Looksy is shown for a selected product group;
- product-image button wording, corner, or offset;
- instructions before upload;
- product-selection strategy;
- mobile-specific presentation.
What should I measure?
Choose one primary metric, such as try-on completion, add-to-cart rate, or conversion rate. Monitor guardrails including page performance, errors, support questions, and returns.How should I interpret the result?
Report counts, rates, sample size, uncertainty, dates, and implementation details. Check whether promotions, stock, traffic mix, or seasonality affected one group differently.Common mistakes
- ending the test when an early result looks favourable;
- testing too many changes at once;
- comparing different product or traffic mixes;
- ignoring device or variant failures;
- treating correlation as causation;
- reporting a percentage without underlying counts.
