Performance marketing agency near Cologne with a practice marketing service for dentists
About SaphirSolution GmbH
SaphirSolution GmbH is an online marketing agency at Karl-Hass-Straße 26 in Niederkassel, in the Rhein-Sieg district between Cologne and Bonn. Sebastian Denzin and Niclas Weskamp founded it in 2012, and Denzin is managing director. The team numbers about 70, and annual revenue is 6.2 million euros. Their work spans SEO, Google Ads, paid social, affiliate marketing, Amazon and marketplace marketing, digital PR, web analytics and web design.
Healthcare is one sector among many. Their practice marketing service addresses doctors in practices and clinics, other health professionals, laboratories and pharmacies, and includes marketing for dentists and doctors. The services are patient-focused SEO for the practice site, Google Ads, conversion tracking, social media, social recruiting to fill staff vacancies, and a market and competitor analysis that leads to a written practice guideline with goals. Work begins with a free consultation, and they can build a plan for small budgets. Local SEO and Google Business Profile management are offered as linked services. The service covers data protection rules but not Germany's healthcare advertising law, and they name no medical or dental clients.
Their general SEO method in Cologne covers local keyword research, Google Business Profile optimisation and location pages, on-page work on content, meta data and internal links, link building, and technical fixes such as Core Web Vitals, structured data and hreflang. They work on WordPress, Shopify and Shopware. SEO is billed as a monthly flat fee with short contract terms and regular ranking reports, and a free SEO quick check is available before signing.
Published results come from other industries. Garden retailer Dehner gained 500% in organic visibility, with monthly traffic value rising from 3,000 to 12,000 euros. rahm GmbH saw visibility up 597% and top-10 keywords up 316.2%. Great Place To Work Switzerland gained 69.5% visibility after a relaunch. The closest health-adjacent example is a senior care service, Goldener Herbst, with about 136% more leads at about 58% lower cost per lead. Named clients include Citroën, REWE, Volvo, Polestar, Koelnmesse, Pilot Pen, JUNG and Zippo.
Review volume is high. Feedbax shows 4.9 from 217 reviews, and Agenturtipp shows 4.9 from 26 reviews alongside a Google score of 4.9 from 216. Reviewers mention quick replies, friendly contact and clear plans. A small share report weak results or a payment dispute. Agenturtipp named them Agentursieger in 2023, 2024 and 2026, and they hold Google Premium Partner status for 2025 and Meta Business Partner status. The suggested minimum is 1,500 euros a month, which points to larger practices, group practices or dental chains rather than single-chair offices.
