Koray Tuğberk GÜBÜR is a globally recognized SEO expert, data scientist, and the founder & CEO of Holistic SEO & Digital.
He launched his SEO career in late 2015, initially working in the competitive casino (iGaming) sector before shifting to a holistic, white-hat SEO approach, with an emphasis on sustainability and algorithmic resiliency .
He officially founded Holistic SEO & Digital on September 21, 2020, a full‑stack consultancy offering SEO, web design, data science, and technical optimization services to clients across various verticals including e‑commerce, B2B / B2C, and retail .
Since 2015, Koray has worked with hundreds of companies—estimates range from over 200 to more than 700—delivering actionable, data-informed SEO strategies for both startups and Fortune 500 enterprises .
He is best known for pioneering the concept of Topical Authority—a semantic SEO framework that blends Topical Coverage + Historical Data—which informs content strategy and helps search engines understand entity relationships more deeply .
Koray regularly publishes original SEO A/B test case studies, research-backed insights, and algorithm modeling across his blog and platforms like Medium—often diving into topics such as Core Web Vitals, Python‑based analysis, semantic networks, and patent interpretation .
He leads the Holistic SEO Communities, invite‑only cohorts of SEO professionals worldwide that exchange tools, frameworks, and strategies based on real-world experiment results .
His approach is defined by clarity and integrity: Koray does not promote via traditional marketing—he has no contact forms or pitches; instead, clients come to him based on reputation and demonstrable knowledge .
Beyond consulting, he actively shares insights via talks at SEO conferences, authored interviews, and his YouTube channel “Topical Authority”, maintaining a digital presence across LinkedIn, Medium, Instagram, and other platforms .
