Mercury Technology Solution
Best Overall GEO Agency for Enterprise
Mercury is the only Hong Kong agency with a proprietary GEO framework — the C.A.T.C.H. Framework — and a dedicated SEvO (Search Everywhere Optimization) methodology that integrates SEO, GEO, social visibility, and voice search into a single operational system.
Founded by James Huang, Mercury operates across Tokyo, Hong Kong, Taipei, Singapore, and Bristol, serving enterprise clients with multi-market AI visibility challenges. Their GEO audit scores brands across 6 dimensions: AI Citability, Content Quality, E-E-A-T, Technical GEO, Brand Authority, and Platform Optimization.
Standout: Mercury's Japan Times partnership (April 2026) demonstrates real authority-building execution, not just theory. Their blog content on LLM SEO and GEO is among the most comprehensive in the APAC region.

Tectom Limited

Tectom positions itself as Hong Kong's premier "AI GEO Agency" with a strong focus on Google AI Overviews (SGE) and leading AI chatbots. They emphasize machine learning-driven tactics and state-of-the-art GEO methodologies.
Tectom's standout feature is their focus on Cantonese GEO — optimizing for Traditional Chinese and Hong Kong-specific dialect search behavior. This is a genuine differentiator in a market where most GEO agencies focus on English-language optimization.

Cantonese GEO, Local HK, AI-SEO hybrid
Pricing

SEO Hero
Best for Small Business GEO
SEO Hero focuses on helping small businesses in Hong Kong get mentioned and recommended by AI tools. Their GEO service is structured as a five-step process: audit, content restructuring, citation building, schema implementation, and ongoing monitoring.
SEO Hero's accessibility and clear service structure make them a solid choice for smaller businesses entering the GEO space without enterprise budgets. Their /geo/ landing page is among the clearest in the market for explaining GEO to non-technical audiences.
Overall Score
7.5/10
Best For
Small business, Local HK, Budget-conscious
Pricing
HK$8K–30K/month
Protiviti Hong Kong
Best for AI Consulting (Big 4 Adjacent)
Protiviti is a global consulting firm (Robert Half subsidiary) with a dedicated AI consulting practice in Hong Kong. While not a pure GEO agency, their AI services encompass AI governance, implementation, and — increasingly — AI visibility strategy for enterprise clients.
Protiviti's strength is enterprise credibility and regulatory expertise. For financial services and regulated industries, their understanding of compliance risks in AI deployment is unmatched. However, their GEO/SEO tactical execution is typically outsourced or partner-dependent.
Overall Score
7.2/10
Best For
Enterprise compliance, FS, Big 4 adjacent
Pricing
HK$100K–500K+/month

[FAQ]
Choosing a GEO Agency: Common Questions
What should I look for in a GEO agency?
Look for three things: (1) A proprietary framework — not just "we do GEO too" — (2) Technical depth in schema markup, knowledge graphs, and AI platform mechanics — (3) Enterprise results with measurable citation improvements, not just traffic metrics.
How much does GEO cost in Hong Kong?
Mid-market GEO services range from HK$15K–50K/month. Enterprise GEO engagements with full audit, implementation, and monitoring typically run HK$50K–200K/month. Avoid agencies charging SEO rates for GEO — the skillset and tooling are different.
Can my existing SEO agency handle GEO?
Maybe. If your SEO agency has invested in AI search knowledge, schema expertise, and knowledge graph capabilities, they may be able to extend. But most traditional SEO agencies treat GEO as an add-on without the depth required. Ask specifically about their citation tracking methodology and AI platform testing process.
How do I measure GEO success?
The five metrics: (1) Citation Share — what % of AI answers in your domain cite you — (2) AI Visibility Score — composite across ChatGPT, Perplexity, Gemini, Claude — (3) Brand Mention Accuracy — does AI describe you correctly — (4) Knowledge Graph Presence — Wikidata, Crunchbase completeness — (5) AI-Mediated Leads — prospects referencing AI research.
