What is a good conversion rate for a UK e-commerce website?
Average UK e-commerce conversion rates are 1-4%, with significant variation by sector, device and traffic source. Fashion is typically at the lower end; consumables and replenishment products at the higher end. A strong Shopify store targeting a specific niche with warm traffic may convert at 5-8%. Below 1% across all traffic warrants serious investigation of the customer journey.
How do e-commerce businesses reduce customer acquisition cost?
By building organic search presence (content, SEO, product page optimisation) that acquires customers without paid cost, by improving email and SMS list marketing that reactivates existing customers at very low cost, by developing referral programmes that use existing customers to acquire new ones, and by optimising paid media targeting and creative to improve conversion rates.
What is the LTV to CAC ratio needed for a profitable e-commerce business?
A minimum LTV to CAC ratio of 3:1 is widely cited as the target for sustainable e-commerce — meaning customer lifetime value should be at least three times the cost of acquiring that customer. Below 2:1 and the business is likely not generating sufficient contribution to cover fixed overhead after acquisition cost. Above 5:1 and there may be opportunity to invest more in growth.
What software do UK e-commerce businesses use?
Shopify is the dominant platform for UK independent e-commerce. WooCommerce on WordPress is widely used for greater customisation. Klaviyo is the leading email and SMS platform. Google Analytics 4 and Meta Pixel provide advertising attribution. Inventory management tools include Brightpearl, Linnworks and Veeqo for multi-channel sellers.
