SEO Galaxy GmbH

What SEO Galaxy GmbH does

SEO Galaxy GmbH is a German search engine marketing agency founded in 2016 by David Hahn and headquartered in Ulmen, Germany. The company operates a dual model combining an agency-style managed service with a self-service platform business. Its service portfolio spans full-service SEO retainers, Google Ads (SEA) management, SEO audits, consulting, content production (including LLM-optimized text), and an education offering. The technology stack rests on a proprietary in-house SEO platform augmented by the Linkonaut AI recommendation engine, which analyzes link profiles, identifies gaps versus competitors, and continuously monitors backlinks across a portfolio of more than 100,000 link sources. The Linkonaut AI, combined with standard SEO tooling (ScreamingFrog, Ahrefs, Sistrix, Semrush, SurferSEO), underpins both the full-service delivery and the self-service Backlink Marketplace at space.seo-galaxy.com.

On the commercial side, SEO Galaxy generates revenue through four streams: (i) monthly SEO retainers starting at €2,000/month with a six-month minimum, (ii) Google Ads management fees starting at €1,500/month on three-month minimums, (iii) transactional revenue from the Backlink Marketplace where content links start at €170 per placement, and (iv) one-time services such as SEO audits, consulting, and content creation. The GTM motion is sales-led and consultation-driven for full-service contracts, complemented by a product-led self-service funnel for the marketplace targeting smaller budgets from €200 upward. The customer base spans e-commerce, IT services, lead generation, and B2B mid-market companies across the DACH region, with named case-study logos including Grailify, Meingartenversand, and Secundo. Reported scale signals include 1,000+ completed projects, 300+ companies served, 200+ reviews, and €50M+ in client revenue influenced, though the company itself is a micro-entity with 1–10 employees and no disclosed external funding.
