Generative Engine Optimisation (GEO) Agency — Hong Kong
Get found in traditional search and get cited in AI-generated answers. A2FF Digital runs SEO and GEO as one integrated system, so a single content investment earns visibility in both traditional search and AI-generated answers.
Search now happens in two places.
Generative Engine Optimisation (GEO) — also called answer engine optimisation or AI search optimisation — is the practice of ensuring your brand is cited in AI-generated answers across ChatGPT, Perplexity, and Google AI Overviews, in addition to ranking in traditional Google search. According to a global consumer study by Bain & Company (2025), 60% of searches now end directly within the AI summary without the user clicking through to any website, meaning buyers are finalizing their purchase decisions based entirely on the AI's response. If your brand is not cited in these AI answers, you risk missing the majority of potential buyers, as two out of three AI citations come from pages users would never see on Google's first page.
SEO and GEO are not competing strategies. They share the same content infrastructure. The content that ranks in traditional search (authoritative, structured, entity-rich) is also the content that gets cited in AI-generated answers. A2FF Digital builds and runs both channels on a single content foundation, so every piece earns visibility in two systems rather than one.
Google, Bing, and Yahoo search results account for a significant share of commercial web traffic. Technical SEO, on-page optimisation, and authoritative editorial content drive ranking in this channel. 58.5% of Google searches now end without a click, which lowers the value of organic rank and raises the importance of content quality.
ChatGPT, Perplexity, Google AI Overviews, Gemini, and Bing Copilot synthesise answers from sources they trust. GEO is the discipline of becoming one of those trusted sources: building entity recognition, structuring content for passage-level extraction, maintaining LLM SEO signals, and maintaining consistent brand signals across the sources each AI platform indexes.
The content that earns traditional search rankings, authoritative, structured, and cited by external sources, is also the content AI systems extract and cite in generated answers. A2FF runs both at once, so a single content investment earns visibility in both channels and the value builds over time.
Google AI Overviews have changed what search visibility means.
Google AI Overviews now appear above organic results for a growing share of commercial queries — synthesising an answer before users ever scroll to a blue link. If your content isn't cited inside that answer, your brand won't appear in it at all.
Zero-click search was already reshaping traffic patterns before AI Overviews arrived: only 8% of users click on any link when an AI summary is present, compared to 15% in traditional search results (Pew Research Center, 2025), which forecasts that traditional search engine volume will drop 25% as users migrate to conversational AI answer engines in 2026 (Gartner, Inc, 2024). The brands cited inside those answers reach the buyer; brands that aren't get skipped for that query.
This is why GEO (also called answer engine optimization, or AEO, or AI search optimization) is no longer optional for brands that depend on search visibility. Google AI Overview optimisation, ChatGPT citation, and Perplexity visibility are now part of the same discipline as traditional SEO, and they require the same underlying investment in structured, authoritative content. LLM SEO is the technical layer that makes this possible: optimising content for how large language models index and cite sources.

SEO and GEO run as one system.
We do not sell SEO and GEO as separate retainers because they require the same content infrastructure. Running them together works better and costs less than running them separately.

One strategy across five AI platforms.
Each AI platform has different citation mechanisms, content preferences, and trust signals. We build your presence across all five platforms at the same time.
ChatGPT draws on web browsing and trusted sources. We build your entity presence and authority signals so your brand surfaces when buyers ask ChatGPT for vendor recommendations in your category.
Perplexity cites sources directly in its answers. Passage-level citation optimisation, structuring your content so specific sentences answer specific questions, is the primary lever for Perplexity visibility.
AI Overviews appear above traditional search results for a growing proportion of commercial queries. We optimise your content for AI Overview inclusion using structured data, entity signals, and E-E-A-T alignment.
Gemini's integration across Google Workspace and Search creates new citation opportunities for brands whose content is structured, authoritative, and entity-linked.
Bing Copilot has significant B2B enterprise penetration through Microsoft 365 integration. We optimise your Bing presence and structured data for Copilot citation alongside Google-focused GEO work.
Frequently asked questions
Generative Engine Optimisation (GEO) is the practice of optimising content and structured data so that AI-powered search engines, including ChatGPT, Perplexity, Google AI Overviews, and Bing Copilot, cite and recommend your brand in their responses.
AI systems cite brands they recognise as authoritative entities on a topic. GEO (Generative Engine Optimisation) builds that recognition through four levers: entity signals via structured data; passage-level citability — specific quotable sentences that answer questions directly; AI crawler access via llms.txt; and authority signals across trusted third-party sources.
Traditional SEO optimises for click-through traffic from search result pages — ranking in Google's blue links. GEO (Generative Engine Optimisation) optimises for citation in AI-generated answers — being named as a source in ChatGPT, Perplexity, Google AI Overviews, Gemini, and Bing Copilot. Both disciplines share the same content infrastructure: authoritative, structured, entity-rich content. A2FF Digital runs both simultaneously.
GEO results typically begin to appear within 6–12 weeks for brands with existing domain authority and clean technical SEO foundations. For brands starting from a weaker baseline, meaningful AI citation visibility generally requires 3–6 months of consistent entity-building and content production.
Yes, and we recommend it. A2FF Digital's SEO and GEO service is intentionally integrated: the content that ranks in traditional search is the same content that earns AI citations. Running them separately creates inefficiency and often undermines both. Our engagements include both disciplines in a single scope.
Yes. We track AI mention rate, citation frequency, brand mention context, and share-of-answer across ChatGPT, Perplexity, Google AI Overviews, Gemini, Bing Copilot and DeepSeek. AI mention rate — what percentage of AI-generated answers on your target queries cite your brand — is the primary performance KPI we report against. Reporting cadence is monthly, with quarterly strategy reviews to adjust content and entity priorities based on citation data.
SEO (Search Engine Optimisation) earns ranked positions in traditional search results through relevance and authority signals. GEO (Generative Engine Optimisation) earns citations in AI-generated answers — in ChatGPT, Perplexity, Google AI Overviews, Gemini, and Bing Copilot — through entity recognition and citation-ready content structure. AEO (Answer Engine Optimisation) is a closely related term — some practitioners use GEO and AEO interchangeably; others reserve AEO for voice search and featured snippet optimisation specifically. The underlying optimisation work is largely the same for both. A2FF Digital covers SEO, GEO, and AEO in a single integrated service — the same content infrastructure that ranks in traditional search also earns AI citations.
