What a UK e-commerce website needs to sell

Key takeaways

A UK e-commerce website needs fast, detailed product pages, clear delivery costs and returns before checkout, a short and trusted checkout, compliance with UK consumer law, and tracking that shows revenue and margin by channel. Most lost sales come from surprise costs, slow mobile pages and unanswered product questions.

• Product pages: real photos, specs, stock status, delivery date and reviews.
• Show delivery costs and returns policy before checkout, not at the end.
• Offer guest checkout and familiar payment options such as cards, Apple Pay and PayPal.
• UK law: pre-contract information, 14-day cancellation for most goods, total prices.
• Track revenue by channel and product, not just sessions.

What makes an e-commerce website effective?

An effective e-commerce website is an online shop that attracts buyers, gives them the information and confidence to purchase, and makes checkout fast and secure, at a cost of acquisition that leaves a profit on each order.

The last part matters. A store can grow revenue while losing money if acquisition and returns costs are not tracked against margin.

Where do online shops lose sales?

Sales are lost at predictable points: slow mobile product pages, missing information, unexpected costs at checkout, forced account creation, limited payment options, and doubts about delivery or returns.

Unexpected delivery charges are among the most common reasons shoppers abandon baskets. Showing them early costs a few clicks and saves many abandoned checkouts.

• Product images that do not show scale, detail or use.
• No delivery date or cost until the final step.
• Mandatory account creation.
• Checkout forms asking for unnecessary information.
• No reviews or reviews that look curated.

What should product pages include?

Treat each product page as a salesperson answering every question a shopper would ask in a physical shop.

• Several real photographs, including scale and in use, plus video where useful.
• Clear title, price including VAT, and stock status.
• Key specifications in a scannable list.
• Delivery cost and estimated delivery date.
• Returns summary with a link to the full policy.
• Genuine customer reviews and questions.
• Product structured data for price, availability and reviews.

• Schema markup for small business websites
• Optimise website images for speed and search

What does UK law require of an online shop?

The Consumer Contracts Regulations 2013 require clear pre-contract information, including the trader's identity and address, main characteristics of the goods, total price including taxes and delivery, payment and delivery arrangements, and cancellation rights. Consumers generally have 14 days to cancel most distance purchases.

Under the Digital Markets, Competition and Consumers Act 2024, drip pricing and fake reviews are banned and the CMA can fine businesses directly. Card payments must be handled in line with PCI DSS, which in practice usually means using a reputable payment provider so card data never touches your server.

How should checkout work?

Keep checkout short and familiar. Offer guest checkout, use address lookup, show a progress indicator, and offer the payment methods your customers use, including cards, digital wallets such as Apple Pay and Google Pay, and PayPal.

Show the total including delivery before the payment step, confirm the delivery date, and send a clear confirmation email with order details and cancellation information.

How do you measure an e-commerce site properly?

Use GA4 e-commerce tracking to record product views, add to basket, checkout steps and purchases with revenue. Link Google Merchant Center for Shopping listings and product feeds. As a working range, online shops typically convert around 1% to 3% of sessions, varying strongly with price and traffic source.

Then connect revenue to margin and returns. Track cost of acquisition by channel against gross margin, so you grow the channels that make money, not just the ones that make sales.

When is a marketplace better than your own store?

Marketplaces such as Amazon, eBay and Etsy bring ready-made traffic and trust, which suits new brands testing demand. The trade-offs are fees, limited customer data and less control over presentation and pricing.

Many UK brands use both: marketplaces for reach, and their own store for margin, repeat customers and brand. Your own site becomes more valuable as repeat business grows.

What does this look like in practice?

A pattern in small UK online shops: strong product photography, healthy traffic, and a high abandonment rate at the final checkout step, where delivery costs appear for the first time.

Showing delivery costs and dates on product pages and in the basket, adding a free delivery threshold and offering guest checkout addresses the most common causes of abandonment. The design barely changes; the surprises disappear.
