What is Ecommerce Website Development?

Ecommerce Website Development — explained without the jargon.

Ecommerce sites have two jobs: rank organically (so you stop paying for every visitor) and convert at top-quartile rates. Most fail at one or both. We build ecommerce stores where the SEO foundations, the conversion logic and the checkout speed all ship together — because they're inseparable. Whether you're launching, replatforming or scaling beyond a theme's limits, we've done the build before.

Why it matters

Three things most teams get wrong about ecommerce website development.

01

Checkout speed = revenue

Every second slower in checkout costs ~7% of conversion. Most stores never measure it.

02

SEO isn't a post-launch task

Category templates, internal linking, schema, faceted nav — these need to be right at build time. Retrofitting costs 5×.

03

Themes have a ceiling

Off-the-shelf Shopify / Woo themes work to ~$2M ARR. Beyond that, custom theme or headless usually wins.

FAQ

Questions you were going to ask anyway.

Shopify vs WooCommerce vs Magento?
Shopify for fastest time-to-market and smallest ops overhead. WooCommerce for editorial / SEO-led brands already on WordPress. Magento for complex B2B, large catalogues, enterprise integrations. We model the trade-off per business during discovery.
What does an ecommerce build cost?
Shopify custom theme: $12K-$35K. WooCommerce custom: $15K-$45K. Magento builds: $35K-$120K+. Headless ecommerce (Hydrogen, custom): $40K-$150K. Pricing varies by catalogue size and integration complexity.
Can you handle B2B / wholesale flows?
Yes — tiered pricing, net terms, customer-specific catalogues, quote workflows, ERP integration. We've shipped 20+ B2B ecommerce builds across WooCommerce and Magento.
Do you do checkout optimisation?
Yes. Shopify Plus customers get custom checkout extensibility. WooCommerce gets one-page checkout, address autocomplete, payment localisation. The checkout is where conversion lives.
Will SEO survive an ecommerce migration?
Yes — see Ecommerce SEO Services for the full discipline. URL mapping, 301 strategy, schema preservation, post-launch monitoring are core to every ecommerce migration we do.
