Koray Tugberk Gübür is widely known in the SEO industry for his deep expertise in Technical SEO and Semantic SEO. If you're diving into his insights, here's a breakdown of his core ideas and contributions in both areas:

🔧 Technical SEO – Koray's Approach
Koray emphasizes website health, crawl efficiency, and indexation control as foundational to any SEO strategy. Key technical SEO concepts he promotes include:

1. Crawl Budget Optimization
Reduce low-value pages from being crawled (e.g., faceted navigation, tag archives).

Use robots.txt, canonical tags, and noindex directives strategically.

2. Site Structure
Prioritizes a hierarchical architecture based on topical relevance, not just URL depth.

Internal linking is structured around contextual clusters and semantic themes.

3. Core Web Vitals
Speed, mobile-friendliness, and interaction latency are essential.

Koray often connects these technical signals to user experience, which Google rewards.

🧠 Semantic SEO – Koray's Specialty
This is where he shines. Koray is known for building topical maps and knowledge graphs for content that aligns with Google's understanding of entities and user intent.

1. Topical Authority Building
Instead of targeting random keywords, Koray builds entity-based content clusters.

Uses semantic relationships to map how concepts and topics relate across pages.

2. Contextual Internal Linking
Every internal link should add semantic depth, not just pass link juice.

Pages are interlinked based on topic closeness, helping Google crawl and categorize them properly.

3. Content Fractal Theory
A concept he developed where every page expands from a core entity, creating mini-ecosystems of content.

Encourages building "semantic layers" — introductory, intermediate, and expert-level content linked in a structured way.

📊 Tools & Techniques He Uses
Inlinks: Entity-based internal linking and on-page optimization.

Oncrawl / JetOctopus: Advanced site crawl analysis.

Google NLP API & GPT-based tools: To simulate how search engines interpret semantics.

🧩 Key Takeaways from His Talks/Case Studies
Don't chase keywords; chase understanding.

Treat your website as a topical hub, not a collection of isolated blog posts.

Internal linking + content depth + entity optimization = rankings without backlinks.

Use semantic HTML, schema.org structured data, and clearly defined content sections.
