Ecommerce Website Development
Stell Media provides ecommerce website development for brands replatforming or launching a new online store. We build on Shopify Plus, BigCommerce, Adobe Commerce and commercetools. Search, product data and speed are treated as requirements from the first sprint, so a better admin experience never costs you organic traffic. Explore our wider commerce services to see how development fits with search and data work.
The problem
Why a Faster Site with Worse Data Is a Worse Site
Most ecommerce replatforming projects improve the back-end experience and quietly damage organic performance. Revenue is usually lost in four places: URL and redirect handling, structured data, facet architecture, and attribute coverage. All four are cheap to design in and expensive to retrofit after launch.
We avoid this by agreeing a performance and discovery budget before design begins. We test against it every sprint, not at the end when nothing can change. That keeps your ecommerce SEO and content foundations intact through the migration.
What You Get with Our Ecommerce Development Service
Every engagement ships these four deliverables.
Storefront Build
A theme or headless commerce build with component-level performance budgets enforced in CI, so speed does not slip as features are added.
Discovery Architecture
Search, facets and category structure are designed around real query data before design starts. This connects directly to our site search and discovery work, so shoppers find the right products from day one.
Migration Safety
Redirect mapping, structured data parity and a rollback plan, all validated on staging with real crawl data.
Speed Budget
Core Web Vitals targets are agreed at kickoff and tested every sprint, not negotiated after launch.
How We Run Ecommerce Replatforming, Week by Week
Architecture
We agree and document the discovery model, data requirements, redirect strategy and performance budget.

Two-week sprints with a live staging URL, performance tested every sprint.
Migration Rehearsal
A full dress rehearsal covering redirects, feeds and structured data before the real cutover.

Four weeks of monitoring on rankings, speed and conversion, with a fix budget reserved.
Stack we work in
Platform-agnostic. We work in whatever you already own and tell you honestly when it is the constraint.
Ecommerce Development FAQs
Themed, unless you have a specific reason that survives scrutiny, because headless moves cost from build into maintenance. We show you the total cost of both for your case before you decide.
