Case Study: Mastering SEO+GEO for YMYL Health in the AI ​​Overview Era

PART I: The Challenge and Initial Foundation

1. YMYL (Your Money or Your Life) and Qigong Industry Context

The health sector has always been one of the most challenging segments in digital marketing, especially in the context of Google's increasingly stringent search algorithms. Qi Gong and Yoga, considered mind-body movement interventions, are currently recommended in clinical practice guidelines to improve health outcomes for a variety of conditions.1 Because of their direct relevance to personal health and wellbeing, Qigong content is classified as YMYL (Your Money or Your Life).2

The YMYL content group must adhere to extremely high standards of compliance. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). For a new Qigong site, this means Google will require clear evidence of professional authority. Not only does the content need to be accurate, but it also needs to be created or moderated by experts, certified coaches, and extensive hands-on experience, similar to traditional medicine or acupuncture experts.3 The biggest challenge is how a brand new domain name can quickly build an Authority and Trust signal to compete with mainstream medical reports and established health platforms.

2. Initial Status: Survey of "White Website" and Indexing Barriers

When receiving this project, the team of experts at Tan Phat Digital determined that the initial status of the website was "completely white." This poses many basic but serious barriers:

First, the domain is completely new, has no SEO history and no significant backlinks. The lack of backlink signals not only reduces Page Authority but also makes it difficult to initially establish Entity recognition. In a YMYL environment, Google tends to "sandbox" (restrict display) of new pages until they prove trustworthy.

Second, the content structure is fragmented. The initial content was thin, focusing on just a few general introductory articles without reasonable internal links or a clear link scheme. The lack of a semantic link diagram (Semantic) like the topic cluster model makes it difficult for search engines to understand the context and Topical Depth of the website.5

Third, basic On-page technical weaknesses have not been thoroughly addressed. The website lacks schema markup, the meta description is not optimized, and the page loading speed is slow. These factors are the core foundation that every SEO project must address to ensure effective data collection and indexing.

Fourth, Google cannot clearly determine which entity this website is, what expertise it has, leading to slow and unstable indexing. This signals a failure to establish the E-E-A-T signaling necessary for the YMYL domain.

3. Strategic Vision: Setting Entity-First and AI-Ready Platform

To overcome the YMYL barrier and the "white website" situation, Tan Phat Digital has determined a three-month strategic roadmap focusing on building Entity before regular keyword optimization. This is based on the observation that Entity recognition is the foundation of E-E-A-T in the modern search environment.6

The key goal in the first 3 months is not only to rank but also to become a trusted reference source:

1. Build a clear Topical Authority and Entity for the brand and related Qigong experts.

2. Achieve Position 0 in AI Overview (AI Search).

Viewing the website as a Qigongspecialized entity rather than just a collection of identified web pages is key to gaining trust from Google and AI Overview.

PART II: PLATFORM STRATEGY AND BUILDING A SPECIALTY ENTITY

The strategy deployed by Tan Phat Digital is a smooth combination of Semantic SEO, to build topic depth, and Technical SEO, focusing on data structure and Entity.

1. In-depth Research and Topical Mapping

A. Intent-Based Keyword Analysis

Keyword research is conducted in-depth on more than 200 potential keywords, not only stopping at search volume but focusing on user intent:

1. Core Topic (Foundation information): Keywords with high search volume such as Qigong, Dantian, practice qigong, qigong industry. These keywords create Pillar (pillar) pages, mainly used to build an Authority foundation.

2. Sub Topic (In-depth research): Topics such as breathing, qi training methods, dantian qi, qigong exercises. This content is designed to deepen Topical Depth, demonstrate the website's specialization, and reinforce Google's understanding of related semantics.5

3. Conversion Topic: Queries with clear transactional intent such as where to learn qigong, qigong classes in Ho Chi Minh City, online qigong. This is the group of target keywords that bring in direct revenue, where the GEO strategy is given top priority.

B. Complete Topical Map Design

Based on the results of intent analysis, Tan Phat Digital designed a detailed Topical Map with more than 50 topic branches, applying the Topic Cluster model (Pillar/Hub and Spoke).5

This model includes a Pillar Page that covers a broad topic (for example, "Comprehensive Guide to Qigong") and a Topic Cluster Page (Cluster Pages) specialize in related aspects (e.g., "Position and Role of Lower Dan Dien," "Basic Breath Training Techniques").8 Topic cluster pages are closely linked to pillar pages and cross-linked to each other (Semantic Interlink).9

The goal of Semantic SEO: This organization not only reduces internal competition (content cannibalization) but also strengthens the ability to rank for the entire related keyword phrases.5 Furthermore, a tightly organized Topical Map, cross-linking professional aspects (like "dan dien") and local factors (like "HCMC classroom"), provided a perfect "knowledge map". This allows AI Overview (powered by Gemini) to use multi-step reasoning to synthesize detailed and reliable answers when users ask complex questions.10

2. Strategy to Strengthen E-E-A-T for the Health Sector

To overcome the Trust barrier in YMYL, Tan Phat Digital's strategy focuses on entity authentication.

A. Building Author Entity and Social Entity

Google requires high transparency about Who creates health content. Therefore, a powerful Social Entity system (Brand + Author) was created.

1. Author Expertise Verification: Each Qigong article is assigned to a specific author (coach, expert). Author bio pages are detailed, listing certifications, practice experience, and links to professional social sites (Social Entity).4 This reinforces E-E-A-T signals by clearly defining responsibility for YMYL content.

2. Build External Authority: Conduct selective Guest Posting on reputable sites in the same field (health, meditation, yoga) to build signals off-site authority. These backlinks not only transmit PageRank but also help Google identify and authenticate the Entity for both the brand and author.

B. Deploy Schema Support for YMYL and Entity

Schema Markup is a key technical tool to underpin E-E-A-T, because it provides clear context and establishes relationships between entities, minimizing ambiguity for search engines.6

• Medical Organization Schema (MedicalOrganization): Home and About Pages Referrals are marked with the schema MedicalOrganization (or Organization with health-related attributes).11

• Connect Entities via @id: Use the @id attribute in the JSON-LD structure to connect organizations with authors (Person), services (Service), and locations (LocalBusiness). This connection creates a page-level knowledge graph 7, helping Google quickly evaluate E-E-A-T without having to infer from unstructured data.

• Chemistry and AI-Ready Schema: Apply FAQPage schema to Q&A articles and HowTo schema to Aerospace exercise instructions Cong.12 This not only supports traditional SEO but is also an important preparation step for content to be easily extracted by AI Overview.

3. Extensive On-Page Optimization

In parallel with building Entity, Tan Phat Digital has comprehensively overcome on-page technical issues.

• Page Loading Speed (Core Web Vitals): Focus on improving core user experience indicators such as LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift).13 Optimized Qigong exercise illustrations (compression, lazy loading) to ensure fast loading speed, an important factor for Local SEO because the majority of local searches happen on mobile devices.13

• Reading Structure and UX: Optimized page structure: Heading, meta, internal links, schema, anchor text, breadcrumbs. The reading experience is improved by using short paragraphs, adding exercise illustrations, short breathing videos, and CTAs that clearly navigate to more in-depth articles. Good UX is considered a fundamental factor to maintain sustainable rankings.

PART III: TECHNIQUES OF INTEGRATING GEO AND AI SEARCH

This is the strategic phase that puts Qigong & Yoga website ahead of traditional competitors by integrating geographic optimization (GEO) and organic search engine optimization (SGE/AI) Search).

1. GEO Optimization for Local (HCMC) and Online Services

The goal is to dominate converting keywords with geographic intent (e.g. "Qigong classes in HCMC").

A. Strategy for Building Hyper-Local Content

Creating Hyper-local content does not stop at listing addresses but creating content hubs specific to each service area.13

• Creating Service Area Pages: Tan Phat Digital has created independent landing pages for core services (Basic Qigong Classes) associated with specific areas in Ho Chi Minh City (e.g. District 1, District 3, Thu Duc).15

• Unique Localized Content:Each page must have unique content, reflecting the area's own community and culture.13 Content includes:

  • Information about local Qigong events or classes Take a free trial lesson in that area.16

  • Integrate embedded maps that clearly indicate class locations.

  • Use local keywords associated with the service (e.g. "Reputable Qigong Instructor in District 3").

• NAP Consistency and Trust Signal: Ensure consistency in Name, Location Address, and Phone Number (NAP) across the entire digital ecosystem are paramount factors, reinforcing the Trust signal for Local SEO.13

B. GEO-Targeted Schema: Entity Location Validation for AI

The use of Schema extends beyond traditional LocalBusiness to enhance locality and AI extraction capabilities.17

• Using geo and hasMap Attributes: Applying Attributes geo (includes longitude and latitude) and hasMap (Google Maps map link) in the JSON-LD schema of local services pages.17

• Enhancing Trust Signal and Local Priority: Using geographic schema helps Google better understand service coverage, increases visibility in the Local Pack, and more importantly, provides structured data for AI Overview when users use conversational queries looking for “recent” services.19 This strategy ensures that when users search for information by location, the website content is prioritized because it provides clearly structured data geographically.14

2. "AI Search SEO" Technique (SGE Optimization)

The key strategy to achieve Position 0 in AI Overview is to optimize content for the extraction and inference capabilities of large language models (LLMs) like Gemini.10

A. Compelling Content Format AI: Q&A Structure Analysis

AI is designed to answer questions, so the content was rewritten by Tan Phat Digital in an expert sharing style, focusing on a natural question-and-answer structure.12

• Create Natural Question-Answer Pairs: Articles are structured to directly address user queries as a Q&A.

• Snippet Optimization: All answers are kept short (about 40–60 words) but must contain enough context necessary for AI to extract into a reliable and independent snippet.12

• AI-Friendly Formatting: Prioritize easy-to-extract formats that Google recommends, like Use bullet points, numbered lists, and clear Subheadings (H2, H3) to segment complex content.20

B. Optimizing Semantic and Structural Language for AI Extraction

AI Overview uses multi-step reasoning, requiring content that is not only readable but also has credibility and a clear semantic structure.10

• Topical Depth and Semantic Interlinking: Cross-link between articles in topic clusters to enhance Topical Depth. This tight connection helps the AI confirm that this website has enough authority to answer all aspects of a topic (Qigong) in depth.5

• Citation goal instead of simple Clicks: The SEO goal has shifted from achieving link ranking to citation (being cited) in the AI summary.22 The strategy focuses on designing content as a complete answer for AI, ensuring the ability to be cited in Position 0.

PART IV: ANALYZING THE RESULTS AND IMPACT OF AI OVERVIEW

After only 3 months of implementing the SEO+GEO integration strategy, the project has achieved outstanding results, demonstrating the success of the Entity-First method in the AI environment Search.

1. Analyzing Google Search Console Data: Evidence of Authority

Actual data from Google Search Console (GSC) provides clear evidence of growth in Authority and Entity recognition.

Summary of GSC Results After 3 Months of Implementation (Digital Attack Strategy)

• Clicks (Clicks/month)

  • Initial Status: $0$

  • Results After 3 Months: $800+$

  • Growth Rate: Infinite

• Impressions (Impressions/month)

  • Initial Status: Very low

  • Results After 3 Months: $2,600+$

  • Growth Rate: Very Strong

• Average CTR (Overall)

  • Initial Status: N/A

  • Results After 3 Months: $11.8\%$

  Overview

Clicks increased from $0$ to more than $800$ clicks/month, and impressions reached more than $2,600$/month. This is a phenomenal growth rate for a new domain in the YMYL sector, which is notoriously difficult to establish Trust. The strong growth in Impressions shows that Google has begun to recognize a website's Entities and Topical Maps, allowing these pages to appear in valuable queries.23 This proves that the website has overcome the initial "sandbox" barrier by establishing a strong E-E-A-T signal from the beginning.

2. "Non-Traditional" CTR Performance: Decoding High Click-through Rates and Position 0 Domination

The biggest highlight of the project was achieving an Average Position of $0.0$ (Position 0) for many converting keywords, accompanied by a CTR exceeding $30\%$. The $0.0$ position usually indicates that the website has been selected as a Featured Snippet or, in the current context, as the primary citation source in the AI ​​Overview.23

A. AI Overview Dominance Mechanism (Position 0)

The fact that the content is displayed in parallel with official newspapers and is identified by Google AI as a reliable reference source is proof of the success of the AI ​​Search SEO strategy. The Q&A format strategy combined with the use of FAQPage and HowTo schema provided perfect snippets, helping AI easily extract information, from which the website was prioritized to display at the top of AI Mode results.12

B. Why Are CTRs High in the Zero-Click Era?

While AI Overview tends to drive zero-click searches, reducing CTR for traditional results 24, overall CTR $11.8\%$ and conversion CTR $>30\%$ show a positive trend:

1. AI is an Authority Amplifier Amplifier): When AI Overview cites the content of the Qigong & Yoga website, it acts as an authoritative referral. In the YMYL (health) field, users see content provided by a source that has been prioritized by AI, they will be more inclined to click to learn more details or convert (sign up for a class).24

2. Intent Accuracy: Converting keywords (e.g. "Qigong class in HCMC") are queries with high action intent. Dominating Position 0/AI Overview for these local queries, combined with GEO optimization, means the site is providing the most immediate and local solution.22 When user conversion intent is accurately met and validated by AI, click-through rates skyrocket.

3. Establish Authority and Identify Entity through AI

Success does not stop at the GSC index. The website has achieved entity recognition. Google has clearly identified the topic Entity as "Qi Gong - Dan Dien - Qi Training". This is a direct result of building a Topical Map $50+$ branch and implementing Schema Entity according to Tan Phat Digital's model.

Furthermore, the website has begun to have its own brand queries. This is a strong signal that the Entity and Social Entity strategies have created trust and brand recall.20 The fact that AI Overview continuously chooses to display website content in the clusters “Health – Meditation – Fitness” is the ultimate testament to E-E-A-T and AI-Readiness.

PART V: LESSONS LEARNED AND RECOMMENDATIONS RESOLUTION

1. Strategic Shift: Keywords to Entities in the AI Era

The Qigong & Yoga case study demonstrates that in the AI Search era, SEOs must move away from focusing on single keywords to building authority entities that cover the entire topic.

Topical Authority built through covering more than $50$ topic branches helped Google understand that the website had comprehensive knowledge of Qigong, a Prerequisites for citation. Implementing Schema MedicalOrganization and Entity Authoring from the start is an important technical tactic to minimize ambiguity and quickly establish Trust for Google.6

2. The Core Differences between Traditional SEO and SEO for AI Overview (SGE)

Optimizing for AI Overview requires a distinctly different mindset than traditional SEO that only aims to get top $10$ results.

Key strategic differences include:

• In terms of Primary Objectives:

  • Traditional SEO: Achieve high rankings (position) 1-10) in SERP.

  • SEO for AI Overview: Become a citation source trusted by AI, appearing in SGE/AI Overview (position 0).22

  • SEO for AI Overview: Interlink Semantic: Cross-link between articles in topic clusters to demonstrate topic depth.7

3. Recommendations for Future YMYL Projects

To maintain dominance in AI Overview, especially in the field of YMYL, future Qigong & Yoga projects need to:

1. Continuously Update Data and Content: Google prioritizes businesses that maintain fresh and structured data.22 Qigong YMYL content should be regularly reviewed and updated to ensure relevance accurate and timely.

2. AI Visibility Analytics Tracking: Track how pages appear in generative search using modern tools and GA4 to measure AI-driven traffic.19

3. Increase Hyper-Localization: Expand GEO pages to neighboring districts of Ho Chi Minh City to create more detailed hyper-local content hubs.13 Integrate detailed Google Business Profiles and encourage local reviews to strengthen Trust signals and Local Pack visibility.14
