Global ecommerce sales hit $6.4 trillion in 2025 — and are on track to reach $7.9 trillion by 2028. That’s a market growing more than twice as fast as physical retail, driven by a simple shift in behaviour: people increasingly prefer to buy online, and the technology serving them keeps getting better at making that easy.
This article looks at where ecommerce is heading and what it means for anyone designing, building, or running an online store.
The scale of ecommerce today
The numbers are worth pausing on before we get into trends. Ecommerce now accounts for roughly 21% of all global retail sales. Around three billion people made a purchase online in 2025. By 2028, half of the global population aged 14 and over will be online shoppers.
The UK sits well above the global average for digital penetration, with online retail accounting for over 30% of all retail sales. For businesses selling in the UK market, ecommerce isn’t a channel to consider adding — it’s the primary channel for most product categories.
Mobile commerce is the majority channel
In 2025, mobile devices account for around 59% of all global ecommerce sales — roughly $3.8 trillion transacted on phones. The implication for responsive web design is direct: a site that doesn’t perform well on mobile is not a site that converts well. Full stop.
Cart abandonment on mobile sits at around 84%, compared to 74% on desktop. The gap is almost entirely explained by poor mobile UX — clunky checkout flows, slow loading, small tap targets, and forms that are painful to complete on a small screen. Page speed alone can explain a significant portion of that: a three-second delay in load time reduces conversions by up to 20%.
Personalisation is no longer optional
Generic product listings used to be fine when online shopping was novel. That’s no longer the case. Shoppers now expect stores to remember them — their preferences, their purchase history, their browsing behaviour — and to surface relevant products without them having to search.
AI-driven personalisation is doing most of that work at scale. Retailers using AI recommendations report up to 26% increases in conversion rates. Stores using AI chatbots have seen 25% boosts in lead-to-customer conversion. The technology is now accessible to independent retailers, not just the Amazons of the world — it’s built into most modern ecommerce platforms as standard.
Personalisation also connects directly to recovering abandoned carts. Triggered abandonment emails with personalised product content show conversion improvements of around 6.7% — and cart recovery flows account for up to 47% of email revenue for beauty and fashion retailers. The stores not running these flows are leaving significant revenue on the table.
The cart abandonment problem hasn’t gone away
Despite all the improvements in checkout technology, the global average cart abandonment rate is holding stubbornly at around 70–72%. Seven in ten people who add something to a basket don’t buy it.
The most common causes are well understood: unexpected shipping costs at checkout (responsible for 48% of abandonment), forced account creation, a checkout process that’s too long, and payment methods that don’t include the shopper’s preferred option. Baymard Institute estimates that large retailers could improve conversion rates by 35% purely through checkout UX improvements — without changing a single product or price.
- 48% of carts abandoned due to unexpected shipping costs
- 55% of users abandon if asked to create an account
- Average checkout flow still has 5.1 steps — unchanged since 2012
- 40% of abandonment emails are opened; 50% of clickers go on to purchase
The design of the checkout experience is where most ecommerce stores have the most room to improve.
Social commerce and new shopping channels
Social commerce — buying directly through social media platforms — grew 19.9% in 2024, reaching $820 billion globally. TikTok Shop, Instagram Checkout, and Pinterest’s shoppable pins are moving a meaningful share of purchases away from standalone ecommerce sites, particularly in fashion, beauty, and lifestyle categories.
For brand owners and ecommerce store operators, this means the ecommerce website is no longer the only place a sale happens — but it remains the place where brand credibility is established and where returning customers come back.
Delivery expectations have shifted
Amazon’s normalisation of next-day and same-day delivery has raised the floor for what shoppers consider acceptable. A significant proportion of UK shoppers will abandon a purchase if delivery options are slower than expected, or if the cost of faster delivery is presented late in the checkout.
Transparency matters as much as speed. Showing clear, upfront delivery costs and realistic timescales — rather than revealing them at the final step — directly reduces abandonment and increases trust. This is a checkout UX problem as much as a logistics one, and it connects to broader principles around designing for customer experience.
Digital wallets and payment diversity
Digital wallets accounted for 53% of global online purchases in 2024 — up from 22% a decade ago. By 2030, an estimated 65% of all ecommerce payments will go through digital wallets. Buy Now, Pay Later (BNPL) is used in around 5% of global ecommerce transactions and is growing steadily, particularly in higher-value categories.
For store operators, the practical implication is straightforward: the more payment methods you offer, the fewer people you lose at checkout. Apple Pay, Google Pay, PayPal, and BNPL options like Klarna have moved from nice-to-have to expected on most UK ecommerce sites.
What this means for ecommerce website design
Most of the trends above converge on the same point: the quality of the shopping experience determines whether someone buys, comes back, and tells others. That’s a design and development problem as much as a marketing one.
The stores performing well in 2025 and beyond are those that treat their ecommerce site design as an ongoing investment rather than a one-time project — continuously improving checkout flows, load times, mobile experience, and personalisation based on real user behaviour.
If your current store isn’t converting the way it should, the cause is almost always identifiable through usability testing and analytics. The data exists. The improvements are usually straightforward. The gap is in acting on them.
