MessageSEO consultant with 20+ years of experience driving organic search performance for global brands including MoJ, Shell, Unilever, Apple, Saga, Legal & General, Superdry, Halfords, Aviva, American Express, PayPal, GSK, British Airways, GetYourGuide, Liverpool FC, and Harrods and many other brands across 10+ markets and languages. I design and build the systems and strategies that make SEO scale: AI-powered SEO automation, content strategy and design, GEO/AEO playbooks for AI Overviews and ChatGPT visibility, and technical roadmaps that connect search visibility to commercial outcomes. Track record across regulated sectors with editorial, medical, and compliance review cycles. CMS migrations retaining 95%+ organic traffic, LLM-assisted SEO workflows that compress days of manual research into hours (60-80% effort reduction), and structured data implementations increasing rich result visibility by over 40%. Known for breaking down complex problems to first principles and translating technical findings into clear, actionable language for non-technical teams.
I've always started with two questions: why and how. Thanks to Simon Sinek, now I know that's the right place to start.
Frequently Asked Questions
What does Hasan Deniz specialise in?
I specialise in technical SEO, GEO strategy for AI-generated search results, and AI-powered SEO automation. While my technical foundation is strong, where I truly excel is Search Intent Modelling (SIM) and Content & Competitor Gap analysis. These two disciplines work together: SIM maps exactly what users are looking for at each stage of their journey, and C&C Gap analysis surfaces the insights competitors are capitalising on that you are not. I translate those findings into content strategies that align precisely with the user journey while being built for AIO and GEO visibility from day one. Sometimes that means restructuring existing content, sometimes embedding new angles into what is already there, and sometimes building entirely new content from scratch. My technical work covers crawl infrastructure, rendering pipelines, indexation control, structured data, and Core Web Vitals.
Who has Hasan Deniz worked with?
I have delivered SEO projects for MoJ, Shell, Unilever, Apple, Saga, Gates, Legal & General, Superdry, Halfords, Aviva, American Express, PayPal, GSK, British Airways, GetYourGuide, PMI, NIHR, Harrods, Liverpool FC, National and many more... I have been contracted by global agencies including iCrossing, Kaizen, Incubeta, Merkle, Wunderman, Phd Media, MGomd, Performics, Kin+Carta, SYZYGY and many more... My work spans SaaS, financial services, insurance, pharmaceutical, healthcare, automotive, retail and e-commerce, travel, FMCG, technology and several other sectors.
Why hire Hasan Deniz as an SEO consultant?
I operate as an embedded consultant, integrating directly with client teams rather than delivering reports from a distance. I have led CMS migrations retaining 95%+ organic traffic, built LLM-powered workflows that reduced manual SEO research by 60-80%, and delivered structured data implementations increasing rich result visibility by over 40%. My approach is data-first: every recommendation is backed by crawl data, search performance metrics, or competitive intelligence. Beyond the technical side, I bring search intent modelling and content & competitor gap analysis together to build content strategies that map directly to the buyer journey and are ready for AIO and GEO from the start.
I also build AI-powered content workflows, but not in the way most people think. Generating quality content with AI is not as straightforward as prompting and publishing. I build structured pipelines where every piece of content starts with a detailed brief that captures the audience, intent, tone, and constraints before any writing happens. The AI executes within those guardrails, and every output goes through a multi-step quality check and revision cycle. The result is content that reads like it was written by a specialist, because the strategy, knowledge base, and quality controls behind it were built by one. I document these processes so teams can maintain momentum after the engagement ends.
What types of SEO engagements does Hasan take on?
I am best suited for technical SEO audits and remediation, CMS or domain migration planning, GEO and AIO readiness assessments, search intent modelling and content strategy design, content and competitor gap analysis, international SEO rollouts across 10+ markets, AI workflow development for SEO operations, and ongoing retainer-based consultancy for brands that need senior-level expertise without a full-time hire.
What I Do
Technical SEO & Migration
Deep technical audits, crawl analysis, and site architecture work that protects organic traffic and rankings during complex CMS migrations, domain moves, and platform rollouts. Resolving indexing issues, improving Core Web Vitals, and building the technical foundation that everything else depends on.
AI-Powered SEO & Automation
Building multi-step LLM workflows that compress days of manual research, classification, and content production into hours. Processing large-scale crawl data, log files, and ranking datasets with AI evals to surface technical issues and content opportunities faster than conventional analysis.
Schema, Entities & GEO
Structured data and schema markup strategies that strengthen entity signals and improve visibility in both traditional search and AI-generated results. GEO and AIO readiness assessments that prepare sites for how search is changing, not just how it works today.
Content Strategy & Multi-Market
Editorial content strategies built from scratch for long and short buyer cycles, mapping search intent to the right audience at each stage. Multi-market delivery across languages with hreflang implementation, local keyword targeting, and coordinated rollouts that maintain organic performance globally.
