Ecommerce Website Development

Most replatforms improve the admin experience and quietly damage organic performance. We build with discovery, data and speed as constraints from the first sprint.

Ecommerce Website Development

The problem

A faster site with worse data is a worse site

Migrations lose revenue in predictable places: URL and redirect handling, structured data, facet architecture and attribute coverage. All four are cheap to design in and expensive to retrofit.

We run builds with a pre-agreed performance and discovery budget, tested every sprint rather than audited at the end when nothing can change.

What you actually get

Every engagement ships these. No line items you cannot point at.

Storefront build

Theme or headless build with component-level performance budgets enforced in CI.

Discovery architecture

Search, facets and category structure designed against real query data before design starts.

Migration safety

Redirect mapping, structured data parity and a rollback plan, validated on staging with real crawl data.

Speed budget

Core Web Vitals targets agreed at kickoff and tested per sprint, not negotiated after launch.

Typical outcomes

0.0s

Median largest contentful paint at launch

+0%

Organic sessions retained above pre-migration baseline

0 weeks

Median build, kickoff to go-live

How we run it, week by week

Weeks 1 to 2

Architecture

Discovery model, data requirements, redirect strategy and performance budget agreed and written down.

Weeks 3 to 9

Build sprints

Two-week sprints with a live staging URL, performance tested every sprint.

Weeks 10 to 12

Migration rehearsal

Full dress rehearsal including redirects, feeds and structured data before the real cutover.

Post-launch

Stabilisation

Four weeks of monitoring on rank, speed and conversion, with a fix budget reserved.

Questions buyers ask us

Themed unless you have a specific reason that survives scrutiny, because headless moves cost from build into maintenance. We will show you the total cost of both for your case.
