What we built, and how we proved it worked.

Each case study here sets out the starting problem, the work we did and the tool we used to measure the outcome on handover day. Clients stay anonymous until they agree in writing to be named, and every figure comes from the project's own test output rather than an estimate.

With the method shown

Four cases, and how each was measured.

Two migrations, one rebuild on a failing server and one recovery from malicious code. Under each card you will find the tools and tests behind its figures.

Geotechnical and structural safety engineeringCorporate site · Migration from a hosted platform39 → 0 competing page pairs

From 39 pairs of pages competing with each other to zero

Pages covering the same topic were competing against each other in search results. The content was re-planned and moved to custom code with service, area, glossary and regulation pages.

258 old URLs: 0 chains, 0 loops, 0 redirects to 404
Competing page pairs: 39 → 0
Content on the 39 retained pages: 3,644 → 57,194 words
Lighthouse: mobile performance 97, desktop 99; accessibility and SEO 100

How it was measured: Redirects were checked with automated tests, page overlap with a keyword-matching audit, and structured data on 123 pages with a validation tool.

Projects are anonymised: we do not publish client names without written consent. Figures are from handover-day tests; live values may change over time.

Our measurement toolkit

Six checks we rely on instead of opinions.

The same tools every time, with dated results in the handover file.

Lighthouse

Performance, accessibility and SEO scores on mobile and desktop; our target at handover is 90 or above.

Redirect tests

Every old address is requested automatically and must reach its new page in a single 301, with no chains, loops or dead ends.

Full-site crawls

A crawler visits every page to catch broken links and errors before launch, and again once the site is live.

Accessibility with axe

Automated audits against WCAG 2.2 AA, run across multiple pages and screen widths.

Structured data validation

Schema markup for organisation, services, products and FAQs is checked node by node with a validation tool.

Automated test suites

Unit, integration and end-to-end tests cover forms, permissions, orders and other business flows.

ContentTechnical SEOEnquiries

Projects are anonymised: we do not publish client names without written consent. Figures are from handover-day tests; live values may change over time.

How these six were measured

The question, and the evidence for the answer.

A migration is judged by its redirects; business software by its permissions and tests.

Measurement method for six case studies
Project	Starting question	How the result was checked
Industrial consultancy site	Move an established site without losing its old addresses?	Redirects tested address by address; speed with Lighthouse; accessibility with a WCAG 2.2 AA automated audit.
Home moving company	Turn two separate sites into one address for local search?	Lighthouse in 22 measurements; accessibility on 80 pages at 6 screen widths; structured data with a validator.
Classifieds platform	Publish listings with the authorisation checks regulation requires?	Scope, database schema and automated test suites; integrations verified in each service's test environment.
Cold storage operator	Move ledger and spreadsheet work into an auditable system?	Permissions enforced on the server; workflows verified by 12 end-to-end test suites; daily automatic backups.
Wholesale accessories manufacturer	Stop dealer orders getting lost between calls and messages?	Order flow tested end to end for all three channels; image conversion and schema checked at handover.
Occupational safety company	Get a technical service firm found by answering buyers' questions?	Content and schema counts checked by automated pre-release tests: SEO audit, broken links, schema validation.

Figures describe the day of handover. Values on live sites can change as content and traffic change.

The same in every project

What you receive at handover.

Nothing is handed over unmeasured. These documents are standard in your project too.

Speed report

Mobile and desktop Lighthouse results with Core Web Vitals values, dated on the day of handover.

Redirect map

If you are replacing an old site, every old address with its new destination and test result, in one table.

Acceptance record

A handover document in which each item of the agreed scope is checked off and signed by both sides.

What we leave out

Why you will not see "traffic up 300%" here.

Traffic, sales and enquiry numbers are our clients' data, and they are shaped by season, advertising and sector, so they say little about the quality of the build.

What we can show is what we controlled: whether redirects worked, how fast pages loaded, whether pages passed accessibility and structured data checks, and whether the tests passed. Once a site is live, we monitor real-user Core Web Vitals against the "good" thresholds: LCP of 2.5 seconds or less, INP of 200 ms or less and CLS of 0.1 or less.

Questions

Questions about these case studies

Why do the case studies not name the clients?

We publish a named reference only with the client's written consent. Projects without that consent are described by sector, scope and measured result. At quote stage, we can arrange a direct conversation with a past client, with their agreement.

Are the figures taken from live sites?

Most are handover-day figures. Where a figure was measured on the live site, the card says so, as with the 8 of 8 live Lighthouse scores.

What is Lighthouse, and why does it matter to us?

Lighthouse is Google's open-source audit tool. It scores a page's performance, accessibility and SEO. We share the report at handover, with 90 or above as the target, so you can see how the site performed on the day you accepted it.

Which tests do you run on business software?

Server-side permission checks, unit and integration tests, and end-to-end suites that walk through real workflows. For example, the cold storage system was checked with 652 end-to-end test checks across 12 suites.

Will our project get the same measurements?

Yes. Every website receives a dated speed report and an acceptance record; a redirect map is added when an old site is replaced.
