FADER Umweltanalytik GmbH was founded over 40 years ago in Karlsruhe and has since developed into the leading environmental laboratory in the region. At the Reichardtstraße 30a location in 76227 Karlsruhe, around 25 highly qualified specialists from chemistry, biology, geology, and engineering work together. The laboratory is DIN EN ISO/IEC 17025:2018 accredited and licensed as a drinking water testing facility per §15 TrinkwV by the state of Baden-Württemberg. What makes FADER unique: The combination of accredited laboratory and engineering office under one roof enables holistic solutions – from sampling through analytics to expert consultation and recommendations.
The Starting Point
FADER Umweltanalytik faced a classic dilemma: For over 40 years, the laboratory in Karlsruhe had been the reliable partner for municipalities, water suppliers, swimming pools, and industrial companies. The 25 specialists enjoyed an excellent reputation in the region – regular customers appreciated the fast turnaround times, accurate analytics, and competent advice. But the internet had overlooked FADER. Anyone googling "drinking water analysis Karlsruhe" found other laboratories. Anyone searching "swimming pool water testing Baden-Württemberg" ended up with competitors. New customers – especially younger facility managers, newly founded water suppliers, or relocated industrial companies – simply didn't know FADER. The digital invisibility was costing the laboratory potential new customers and threatening its long-term market position.
Our Approach
Our strategy for FADER was based on three pillars: First, we developed a comprehensive local SEO strategy for the entire Baden-Württemberg region, focusing on Karlsruhe, Pforzheim, Rastatt, Baden-Baden, and surrounding districts. For each of the five core areas – drinking water, swimming pools, groundwater, technical hygiene, and sediments – we created optimized service pages with expert content. Second, we optimized the Google Business profile for maximum local visibility: regular posts, laboratory photos, Q&A section, and active review management. Third, we implemented Schema.org markup for all services to stand out in search results with rich snippets.
Detailed Description
The story of FADER Umweltanalytik GmbH is one of continuous expertise. Founded over 40 years ago, the laboratory at Reichardtstraße 30a in 76227 Karlsruhe has developed into the competence center for environmental chemistry in the Karlsruhe Technology Region. What began as a small specialty laboratory is now a multidisciplinary team of around 25 experts from chemistry, biology, geology, and engineering.
What makes FADER special is the combination of accredited testing laboratory and engineering office under one roof. Customers receive not just precise measurements, but holistic solutions: from proper sampling through accredited analytics to qualified consultation and concrete recommendations. This integration makes FADER unique in the region.
As a DIN EN ISO/IEC 17025:2018 accredited laboratory and Baden-Württemberg licensed drinking water testing facility per §15 TrinkwV, FADER meets the highest quality standards. This accreditation is not an end in itself – it guarantees customers that every analysis is performed according to internationally recognized methods and that results will hold up before authorities and courts.
FADER has specialized in five core areas covering the entire spectrum of water and environmental analytics: 1. Drinking Water: From routine monitoring for water suppliers to individual samples for well owners – FADER analyzes all relevant parameters according to TrinkwV. Especially in demand: Legionella testing for apartment buildings and commercial properties.
2. Swimming Pools: Public pools, hotel pools, whirlpools, and private pools – FADER tests water quality according to DIN 19643 and advises on problems with chlorine, pH levels, or microbiological contamination. 3. Groundwater: For industrial sites, municipalities, and environmental consultants, FADER analyzes groundwater samples for pollutants, nutrients, and physico-chemical parameters.
4. Technical Hygiene: Air conditioning systems, cooling towers, humidification systems – wherever water circulates in technical systems, hygiene problems can arise. FADER tests for Legionella, Pseudomonas, and other pathogens according to VDI 6022 and VDI 2047. 5. Sediments and Incidents: In case of environmental damage, water contamination, or suspected cases, FADER performs forensic analyses and creates court-proof expert opinions.
FADER's digital transformation began with comprehensive keyword research. We identified over 200 relevant search terms – from "drinking water analysis Karlsruhe" to "Legionella testing Pforzheim" to "swimming pool water lab Baden-Württemberg". For each term, we analyzed search volume, competition, and user intent.
The content strategy followed the pillar-cluster model: For each of the five core areas, we created a comprehensive pillar page with all important information, FAQs, and recommendations. These were supplemented by more specific sub-pages – such as "Legionella testing for landlords" or "Solving swimming pool water problems".
The SEO campaign for FADER demonstrates what strategic search engine optimization can achieve for a regional laboratory: Organic traffic +72% within 12 months, Google Maps views +340% (from average 450 to over 1,980 per month), top-3 positions for all relevant local search terms, +58% more contact inquiries via website, noticeably more first-time inquiries from municipalities, facility managers, and industrial customers.
