Murat Ulusoy

Short biography

Working in the SEO discipline since 2003 — first as an in-house specialist, then since 2005 as founder and managing director of SUMAX in Dortmund. The focus is on international engagements with structural visibility challenges: DACH brands with expansion ambitions, large groups with fragmented entity signals, B2B publishers in regulated markets.

The work combines classical technical SEO (crawling, indexing, schema architecture) with the disciplines that determine visibility in generative systems in 2026: Generative Engine Optimization (GEO), entity engineering, passage ranking and multi-source agreement.

Areas of expertise

• Technical SEO & architecture: crawlability, indexing, Core Web Vitals, Schema.org, JavaScript rendering, log file analysis
• Generative Engine Optimization: cross-model audits, passage citability, AI crawler policy, llms.txt architecture
• Entity engineering: Wikidata, Knowledge Graph, sameAs consolidation, cross-domain identity anchoring
• Online reputation management: sentiment monitoring, RDI framework, E-E-A-T architecture, crisis playbooks
• International SEO: hreflang systems, multilingual entity bridging, corpus compensation

Methodology & working style

Every engagement begins with a documented baseline: technical audit, entity status, cross-model prompt evaluation. From there a prioritised action plan is derived — with clear KPIs, milestones and measurement windows. Implementation is hands-on, in direct collaboration with internal teams, not as black-box delivery.

The tool stack (56 tools in active use) is fully documented. The benchmarks every engagement is measured against are publicly available.
