Before You Build: The Decisions That Matter
The biggest mistakes in starting an online store happen before a single line of code is written. Taking time to validate your product, understand your market, and make the right platform choice saves months of expensive pivots later.
Step 1: Validate Your Product Idea
Before investing in a full store, validate that people will pay for what you plan to sell. Talk to potential customers. Check search volume for product-related keywords using a free tool like Google Keyword Planner. Look at competitor stores — if established businesses are selling similar products profitably, that is validation. If no competitors exist, ask why before assuming you have discovered an untapped market.
Consider selling a small batch through an existing marketplace (Etsy, eBay, Amazon) before investing in your own store infrastructure. Real sales from real customers are the strongest possible validation.
Step 2: Choose Your Platform
Shopify — Best for most new stores. Fastest setup, best checkout conversion, largest app ecosystem. From £25/month. Choose this if you want to be live quickly and focus on selling rather than building.
WooCommerce — Best if you are already on WordPress or need maximum flexibility. Free plugin but requires paid hosting. Choose this if you want full ownership and lower long-term platform costs.
Squarespace Commerce — Best if you have a small catalogue and visual brand is paramount. From £36/month. Choose this if you are a creative brand selling a curated product range.
Gumroad or Lemon Squeezy — Best for digital products. No monthly fees, percentage of sales. Choose this for ebooks, templates, courses, or software.
Step 3: Set Up Your Store
Register your domain name before setting up your store — use your business name if available or a clear descriptive domain. Keep it short, memorable, and easy to spell. Set up your platform account and connect your domain.
Choose a theme that fits your brand — most platforms have free and paid themes. Do not spend days customising a theme at this stage. Get a working store live first and refine the design iteratively.
Add your products with clear photos, accurate descriptions, pricing, and variants (sizes, colours). Product photos are the single biggest driver of ecommerce conversion rates — use good lighting, consistent backgrounds, and show products in use where possible.
Step 4: Configure Payments and Shipping
Set up a payment processor — Shopify Payments, Stripe, or PayPal are the standard choices. Enable multiple payment methods: card payments are essential, PayPal adds trust for customers who prefer it, and buy-now-pay-later options (Klarna, Afterpay) can increase average order value.
Define your shipping strategy: free shipping (built into product pricing), flat rate, or carrier-calculated. Free shipping above a threshold (e.g. free shipping on orders over £50) is a proven tactic for increasing average order value.
Step 5: Legally Required Essentials
Before driving traffic to your store you need: a Privacy Policy (required by GDPR and CCPA), Terms and Conditions, a Returns and Refund Policy (legally required in the UK and EU), and cookie consent if you use any tracking. Most ecommerce platforms include policy templates — customise them for your specific business rather than using them unmodified.
Register your business appropriately for your jurisdiction. Understand your VAT obligations — in the UK, registration is required when turnover exceeds £90,000, though you may choose to register earlier.
Step 6: Set Up Analytics and Email
Install Google Analytics 4 and connect it to your store for ecommerce tracking. Set up Google Search Console for organic search monitoring. Install Facebook Pixel if you plan to run Meta ads.
Set up an email marketing account (Klaviyo for Shopify, Mailchimp or MailerLite for others) and create at minimum a welcome email and an abandoned cart sequence. These automations work from day one and recover revenue that would otherwise be lost.
Step 7: Drive Your First Traffic
Do not wait for organic SEO to drive traffic — that takes months. For your first sales: share with your personal network, post in relevant communities and forums (with value, not spam), run a small paid social campaign on Meta or TikTok to test messaging and find your audience, and if you have an existing email list, send a launch announcement. Aim for your first 10 sales before optimising anything — real customer feedback is worth more than perfect conversion rate optimisation on zero traffic.
