What actually moved

Three changes did most of the work

Answer the rule, win the job

Nobody wakes up wanting a lightning rod — they read a building regulation, an insurance clause or an inspection notice. The pages were built around those questions, so "blitzableiter pflicht" now lands STS on page one.

A reference library, not a brochure

DIN 18014, earthing, equipotential bonding, surge protection, inspection intervals — each explained on a page of its own. 343 keywords rank today, against a handful two years ago.

Found on the map, not just the web

992 people viewed the Business Profile, 272 asked for directions and 44 clicked through to the site — a whole channel that never touches a search result page, and the one a local trade lives on.

The brief

A specialist trade nobody could find

STS runs two businesses off one domain: Steuerungstechnik — industrial electrical assembly, cable laying and control systems — and Blitzschutzbau, lightning protection for homes, commercial buildings and public infrastructure. Skilled, certified, and drawing about two organic visits a month in a country where lightning protection is written into building law. The brief was to make the expertise findable in German search.

What I did

  1. Map the regulation, not the service

    The German search demand around Blitzschutz is compliance-shaped: is it required, which norm applies, how often must it be inspected. That map decided every page that followed.

  2. Build the Ratgeber

    A technical knowledge hub answering one question per page — 115 articles across lightning protection, earthing, equipotential bonding and surge protection.

  3. A page for every sector

    Eighteen service and sector pages, so a hospital's facilities manager and a logistics operator each land on copy written for their building.

  4. On-page cleanup across the domain

    Titles, headings, internal links and metadata rewritten against that map. On-page score now 89 out of 100.

Semrush and Ubersuggest, a GTmetrix run, and six months of Google Business Profile — exported 27 and 28 August 2026. The two SEO tools estimate organic traffic differently, so both are here rather than only the flattering one. Nothing recreated, nothing rounded up.
