Three working areas
What this guide helps you decide
Improve the commercial journey as a connected system—from product discovery and purchase confidence to retention and repeat value.
Retention and customer value
Use post-purchase service, replenishment, relevant communication and loyalty mechanics to increase value without relying on constant discounting.
Go to chapter ↓Measurement and experimentation
Prioritise experiments using customer evidence, commercial impact and implementation effort, then measure beyond a single conversion-rate change.
Go to chapter ↓The practical answer
What to do first
E-commerce growth comes from improving one connected commercial journey: help the right customer find and trust the right product, remove avoidable purchase friction, then earn a repeat order through service and relevance. Test changes against margin and customer value, not conversion rate alone.
Chapter 1
Merchandising and conversion
Help customers find, compare and trust the right products through useful navigation, complete information and fewer avoidable checkout obstacles.
Merchandising begins with how customers choose. Build categories and filters around meaningful product differences, write complete product information and make price, availability, delivery, returns and support easy to find. Checkout optimisation cannot compensate for uncertainty created earlier in the journey.
Actions to take
- Observe site search, support questions and failed journeys.
- Make comparison criteria, total cost and delivery expectations explicit.
- Test the complete mobile path from discovery to confirmation.
Chapter 2
Retention and customer value
Use post-purchase service, replenishment, relevant communication and loyalty mechanics to increase value without relying on constant discounting.
Retention is earned after payment. Accurate fulfilment, useful order communication, simple returns and responsive support shape the second purchase. Use replenishment or recommendations when they fit the product cycle; avoid turning every post-purchase message into a discount.
Actions to take
- Audit fulfilment, returns and customer communications.
- Identify natural replenishment or repeat-use moments.
- Measure repeat purchase and contribution margin by customer cohort.
Chapter 3
Measurement and experimentation
Prioritise experiments using customer evidence, commercial impact and implementation effort, then measure beyond a single conversion-rate change.
Prioritise tests using customer evidence, expected commercial value, effort and risk. Measure the whole effect: conversion, average order value, margin, returns, support demand and repeat behaviour. Segment new and returning customers so a blended rate does not hide opposing results.
Actions to take
- Keep a prioritised experiment backlog with evidence.
- Define guardrails such as margin, returns and support contacts.
- Record implementation details and review delayed effects.
Decision table
Weak signals versus a stronger system
| Decision | Weak approach | Stronger approach |
|---|---|---|
| Improve conversion | Copy a competitor’s checkout | Find the specific uncertainty or obstacle in your own journey |
| Drive repeat sales | Send constant discounts | Use service, timing and relevant replenishment or discovery |
| Choose a test | Pick the easiest interface change | Prioritise customer evidence, commercial impact, effort and risk |
| Read results | Celebrate conversion rate | Review margin, returns, support demand and cohort value together |

FAQ
Questions teams ask in practice
What should an online shop improve first?
Fix failures that block trust or completion: unclear product information, hidden costs, weak mobile navigation, payment errors and uncertain delivery. Use customer evidence before redesigning the interface.
Is free delivery always better for conversion?
It may improve completion but damage margin or change basket behaviour. Test the threshold and communication while measuring contribution margin, not conversion alone.
What consumer information must be shown?
EU and Portuguese rules cover identity, product characteristics, total price, delivery and withdrawal rights. Requirements vary by offer; use official guidance and legal advice.
