Setting up an online store has never been easier. Making it actually sell, however, is another story. Every day thousands of e-commerce sites open that get visits but barely take any orders: they have a nice catalogue, sure, but not a selling machine. The difference between a store that withers and one that grows is rarely the product; it's how the buying experience is designed.
At aatsoft, a web development studio in Manresa (Barcelona), we build and optimise online stores for businesses. In this guide we share the five keys that really move the needle and a checklist so you don't launch with holes.
An online store isn't a catalogue: it's a sales process
The most common mistake is treating an e-commerce site as a digital shop window: upload products, set prices and wait. But selling online means guiding a person, step by step, from the moment they arrive until they pay and come back. Every friction along the way —a bad photo, one extra checkout step, a surprise shipping cost— is a sale that slips away. These five keys target exactly those leak points.
5 keys to an online store that sells
1. A product page that convinces
It's your 24/7 salesperson. It needs good photos from several angles, a description that answers doubts instead of repeating specs, a clear price, availability and a buy button you don't have to hunt for. If the page doesn't answer «why should I buy this?», the customer leaves.
2. A frictionless checkout
The abandoned cart is the e-commerce's biggest leak. The fewer steps and fields, the better: allow guest checkout, show shipping costs as early as possible and offer the payment methods your customer expects. Every obstacle at payment is an excuse to give up.
3. Trust and secure payments
Buying means handing money and data to a stranger. Reduce that fear with trust signals: real reviews, a clear returns policy, secure-payment badges, visible contact details and, of course, an HTTPS connection. Trust isn't a detail: it's what closes the sale.
4. Mobile and speed
Today a large share of purchases are decided and completed on the phone. If your store isn't comfortable on mobile or is slow to load, you lose customers before they even see the product. A fast, mobile-friendly store sells; a slow one frustrates.
5. Traffic: getting found
The best store doesn't sell if no one reaches it. You need a steady flow of qualified visits through SEO (optimised product and category pages), content and, when it makes sense, advertising. Building the store is half the work; the other half is attracting the people who will buy.
Before launching: the essential checklist
Before opening your store to the public, check that you have the basics well covered.
A secure payment gateway, products with good photos, clear shipping and returns terms, a search with useful filters, legal compliance in order (GDPR, cookies and legal notice) and analytics switched on to measure what works. Without these foundations, you're selling blind.
Standard platform or custom store?
There's no single answer. Solutions like WooCommerce, Shopify or PrestaShop let you start fast and are perfect for many businesses. But when your catalogue is large, your logistics are unusual or you need integrations with your ERP or suppliers, a custom store —or a well-adapted standard platform— usually performs better in the medium term. The right call depends on your business, not on the trend; that's why it's worth analysing before you invest.
