1. Executive Summary & Overview

Founded 20 years ago in Europe by clinical endocrinologist Dr. Gilles Terracol and operating in Turkey since 2013, SDM Scientific Nutrition and Diet Solutions (sdmkalibradiyeti.com) is a specialized clinical medical nutrition company. In 2018, SDM joined Spain-based PronoKal Group, a global leader in medically supervised weight loss. Offering high-protein, low-carbohydrate nutritional formulations developed for Very Low-Calorie Ketogenic Diet (VLCKD) programs, SDM Kalibra delivers personalized clinical weight loss solutions under physician and dietitian supervision.

SDM Kalibra partnered with Zeo to establish an authoritative clinical nutrition search architecture fully aligned with medical E-E-A-T guidelines. By creating dedicated dietitian profiles, structuring ketogenic nutrition science hubs, and resolving technical crawl inefficiencies, the engagement delivered a +31% increase in organic clicks and a +46% improvement in average SERP ranking positions, establishing SDM Kalibra as a trusted clinical diet reference.

2. Challenge & Market Context

Clinical nutrition, weight loss diets, and ketogenic therapies operate under the most aggressive YMYL scrutiny:

Strict Health & Weight Loss YMYL Scrutiny: Google applies the highest level of E-E-A-T scrutiny to weight loss and medical diet queries, penalizing unverified commercial diet claims.
Absence of Expert Author & Dietitian Profiles: The initial website lacked dietitian bios, clinical credentials, and scientific references, preventing search engines from recognizing medical authority.
Intense Competition from Hospital Portals: Competing in the same search result sets against high-authority hospital portals (Acıbadem, Memorial) publishing generic diet articles.
Technical Crawl Inefficiencies & Missing Meta Data: Crawl budget was diluted by unstructured content hierarchies, duplicate URL paths, and absent structured data markup.

3. Objectives & KPI Targets

The strategic clinical nutrition SEO roadmap outlined clear medical authority targets:

Medical E-E-A-T Architecture Implementation: Establish undeniable clinical authority by showcasing certified dietitian educator profiles and peer-reviewed scientific studies.
Ketogenic Diet SERP Dominance: Secure top-3 organic rankings for high-intent clinical nutrition queries ("düşük kalorili ketojenik diyet", "sdm diyeti nasıl yapılır", "kalibra diyeti aşamaları").
Ranking Position & Organic Click Acceleration: Achieve a minimum +30% increase in organic clicks and improve average ranking positions by +40%.
Medical Structured Schema Deployment: Implement structured MedicalWebPage, Person (Dietitians), Diet, and FAQPage JSON-LD schema.

4. Strategy & Innovation

Zeo engineered a clinical E-E-A-T and nutritional science topic cluster framework:
