Who is Justin Hà?
With over 4 years in SEO and 2 years running live GEO campaigns on global projects, I have built a practice around one thing: making brands cited and recommended inside AI-generated answers across every major platform. My work spans all 9 generative platforms, 9 international markets, and websites running in 8 languages including Chinese, Japanese, Korean, Spanish, French, German, English, and Vietnamese.
My specialisations cover Hospitality GEO, AI Branding, Programmatic SEO, GEO for B2C businesses, Local SEO, and Luxury Brand visibility. In 2026, I am running 10 active GEO projects simultaneously as a Senior Global SEO/GEO Specialist. Every strategy is built on real campaign data, documented results, and tested execution across industries and markets.
The AI Search Shift
Industry data on why GEO is no longer optional for serious brands.
Google internal data, 2024 — AI Overview now surfaces in >40% of queries in certain verticals
Salesforce Research, State of the Connected Customer, 2024
Semrush AI Visibility Report Q4 2024 — AI citations drive higher-intent visits
OpenAI, 2024 — Perplexity crossing 100M monthly queries/day by late 2024
Gartner, 2024 — Buyers consult LLMs before contacting vendors
SparkToro, 2024 — AI answers reducing clicks for informational queries
justinha.info.vn — 80% AI visibility for Holiday Inn Saigon Airport in 3 months without backlinks or paid PR
Why GEO Now
The window to build AI authority before competitors is closing fast.
Traditional SEO still matters — but it only answers half the equation in 2025. Millions of buyers now skip Google entirely, asking ChatGPT or Perplexity for recommendations. If your brand isn't in those answers, you don't exist to them.
80% AI visibility across ChatGPT and Google AI Mode in 3 months. No PR spend. No link outreach. Pure GEO content architecture and entity optimization.

The Cost of Waiting
Brands that delay GEO lose the window to build AI authority first.
- Competitors who establish AI citations today will be embedded in LLM training patterns over time, making displacement harder.
- AI Overviews are already reducing organic CTR by 15–30% for informational queries — the traffic is shifting now.
- LLMs prefer brands with clear entity signals, structured data, and consistent off-site mentions — all of which take time to build.
- Early GEO movers in your niche will own the recommended brand slots before your strategy even launches.
GEO Methodology
A 5-phase framework developed over 2+ years of hands-on AI visibility work.
Benchmark your brand across ChatGPT, Perplexity, AI Overview, and Gemini using 20–30 real-user prompts. Map where you appear, where competitors dominate, and what gaps exist.
Schema markup for entities, FAQ, and HowTo. LLMs.txt setup. Knowledge Graph entity strengthening. Site architecture review for LLM crawlability and AEO readiness.
AI-optimized content assets written with answer-first formatting, semantic clustering, and embedded structured data. Each piece is engineered to be cited, not just ranked.
Off-site entity mentions on Reddit, LinkedIn, YouTube, and industry publications — the platforms LLMs actively learn from. Strategic distribution to reinforce brand entity across the web.
Monthly prompt testing across all target AI platforms. Visibility tracking with before/after documentation. Actionable insights and continuous refinement based on real AI responses.
