SGM Lektra — multi-domain technical SEO for an industrial manufacturer since 1977

The challenge

SGM Lektra has been manufacturing instruments for industrial processes and the integrated water cycle since 1977 — flow, pressure, level, field communication, complete automation solutions. The engineering heritage is deep; the brand serves an international audience across multiple regional domains, in multiple languages, selling into procurement teams who don't search the way B2C audiences do.

That mix is unusually punishing for an SEO architecture. Multi-domain rollout, multilingual content, technical vocabulary that doesn't behave like consumer query language, media- and PDF-heavy product pages, and the perennial migration risk that follows any restructure of a multi-locale site. The brand needed a web stack with the same discipline as the products it sells.

The approach

A multi-phase engagement covering both full-stack development and technical SEO, embedded enough to ship rather than recommend. Custom WordPress builds where the off-the-shelf options didn't fit the multi-domain architecture, structured data deployed across the templates that mattered, performance work tuned for media-heavy industrial pages, and a multi-domain migration executed without traffic loss.

The discipline that B2C SaaS sites take for granted — schema, hreflang, canonical strategy, redirect maps — applied to an industrial B2B context where most agencies don't bring the technical depth to ship it cleanly.

What I built

The work spanned six recurring workstreams, sequenced across the multi-phase engagement:

• Custom WordPress development

  Bespoke templates and back-end logic where the off-the-shelf themes and plugins didn't fit the multi-domain, multi-language structure. Built to be maintainable by the internal team, not handed over as a black box.

• Multi-domain architecture

  Regional domain strategy with consistent technical foundations across every market — shared logic, locale-specific content, and a clear canonical model so search engines didn't have to guess.

• Multilingual implementation

  Hreflang, locale routing and translation workflow set up so the international content was actually discoverable per region, not just rendered.

• Structured data rollout

  JSON-LD deployed across the templates that mattered for an industrial brand — Organisation, Product, Article, Breadcrumb — making the catalogue machine-readable and earning the rich-result treatment where applicable.

• Performance optimisation

  Industrial product pages are media- and PDF-heavy by nature. Load-time and Core Web Vitals work tuned for that reality rather than the lighter-weight SaaS pages most performance advice is written for.

• Multi-domain migration

  Redirect maps, equity protection and the careful sequencing that lets a multi-locale, multi-domain restructure ship without a step-down in the traffic graph.

The outcome

The migration is the headline because it's the easiest outcome to lose. The harder, less visible win is the work behind it: a multi-domain architecture that holds, a structured-data layer that makes the catalogue machine-readable across locales, and a performance foundation that survives PDF-heavy product pages.

What this case shows

Industrial B2B is its own discipline. The audience searches differently, the content is more technical, and the architecture has to carry the weight of a multi-region, multi-language catalogue rather than a single-locale marketing site. Most agencies don't bring the technical depth to ship that well, especially when a restructure or migration is involved.

The work for SGM Lektra is what technical SEO done with the same discipline as the engineering it supports looks like — applied to a B2B sector where that discipline is rare.
