Generative Engine Optimisation (GEO) is becoming an increasingly important part of search marketing as customers turn to ChatGPT, Google AI Overviews, Gemini, Perplexity and other AI tools for recommendations and answers.
Unlike traditional SEO, GEO focuses on making a brand, website and content easier for generative AI systems to understand, trust, mention and cite.
The agencies below have therefore been selected specifically for their stated GEO or AI search capabilities, rather than simply being SEO agencies that have published an article about artificial intelligence.
Rankpage Singapore approaches GEO as an extension of search optimisation, combining traditional SEO with a proprietary GACB framework designed to strengthen the entity and citation signals used by AI engines.
The GEO agency process begins with an AI discovery audit before moving into entity alignment, structured data, LLM-friendly content and AI citation tracking. The agency specifically works on signals such as consistent business information, Knowledge Graph relationships, external authority sources and content structures that make individual passages easier for AI systems to extract.
Rankpage states that it pioneered its Answer Engine Optimisation work in 2024 before expanding further into GEO. Its Singapore offering targets visibility across platforms including ChatGPT, Gemini, Perplexity and Google AI Overviews.
Uses its own framework to build entity authority and citation signals alongside conventional SEO.
Reviews structured data, existing AI recognition and the wider digital footprint before developing a GEO strategy.
Works on consistent brand information, semantic relationships and Knowledge Graph signals.
Structures content around direct answers, factual information and passages that generative engines can more easily extract.
Ideal for: Singapore businesses that want traditional SEO, AEO and GEO managed as one integrated search strategy rather than separate campaigns.
AI Studio is an AI-focused Singapore digital agency that treats GEO as a dedicated discipline alongside AEO and SEO.
Its published GEO methodology goes beyond rewriting webpages for conversational keywords. AI Studio discusses crawler access, llms.txt, JSON-LD schema, citation-ready content formatting, topical clusters and third-party mentions as different layers of an AI-search strategy.
The agency also publishes its own AI visibility measurements. For example, it reported approximately 37,600 Bing Copilot citations in July 2026 compared with 754 in June after eight structured guide pages went live.
GEO forms a central part of the agency’s positioning rather than being a minor SEO add-on.
Covers crawler access, structured data and machine-readable website architecture.
Structures content and factual information around passages AI systems can retrieve and reference.
Ideal for: Businesses seeking an AI-native agency that combines technical GEO, structured content, authority signals and AI visibility measurement.
Digitrio takes a particularly integrated SEO + GEO approach.
Instead of presenting generative search as a replacement for Google SEO, the Singapore agency positions GEO as another layer of organic search strategy. Its work is intended to improve both conventional search rankings and the likelihood that information is discovered and referenced by ChatGPT, Gemini, Perplexity and Google’s AI search experiences.
Digitrio describes GEO as “SEO for AI” and concentrates on making a business, its expertise and its content understandable enough for generative engines to recognise it as a useful source.
Builds generative search optimisation on top of existing organic search foundations.
Develops content around the questions and information generative engines need to answer.
Improves how pages communicate information to ChatGPT, Gemini, Perplexity and Google AI.
Ideal for: Businesses that already understand the value of SEO and want to extend an organic search strategy into AI search without treating the two channels separately.
Stridec is an SEO-focused Singapore agency with an unusually detailed public GEO methodology centred on entity differentiation and measurable AI citations.
Rather than tracking one blended “AI visibility score”, Stridec says it measures individual AI surfaces separately because ChatGPT, Google AI Overviews, Gemini, Perplexity and other engines can retrieve and display sources differently.
It also publishes unusually concrete GEO examples. Stridec states that its Qwang Coffee test used an 11-day-old Shopify domain with no backlinks, advertising or Google Business Profile, which was named first in a Google AI Overview for a commercial query 48 hours after the relevant page went live.
Focuses heavily on defining exactly what a business is and reinforcing that category positioning consistently.
Checks whether target queries actually generate AI answers and which sources currently appear.
Tracks individual queries, engines, markets and dates instead of relying only on general visibility metrics.
Ideal for: Businesses that want a technically detailed GEO methodology with particular emphasis on entity positioning, content production and prompt-level citation measurement.
BThrust combines its established digital marketing background with an end-to-end GEO service covering both technical and authority-building work.
The Singapore agency has operated since 2014 and now applies that search experience to generative platforms. Its GEO scope includes audits, conversational query mapping, AI-ready content, schema, E-E-A-T and entity development, link building, digital PR and ongoing AI visibility monitoring.
It specifically includes backlinks, authoritative brand mentions, knowledge graph optimisation and digital PR as signals that can improve the credibility generative engines associate with a business.
Reviews SEO performance, AI visibility, technical health, structured data, content and online authority.
Builds content around conversational searches and user intent rather than keywords alone.
Strengthens identifiable business entities, expertise and authority signals.
Ideal for: SMEs and established businesses looking for GEO within a wider digital marketing programme that can also cover technical SEO, content, authority building and digital PR.
MediaPlus Digital structures its AI search service around a progression of SEO → AEO → GEO.
Its approach first strengthens the underlying website and SEO foundation, then makes information easier for answer engines to extract before targeting citations and recommendations inside generative AI responses.
Its GEO service covers ChatGPT, Gemini, Perplexity and Google AI Overviews, with traditional search remaining part of the overall programme. This makes the offering somewhat different from pure GEO boutiques that concentrate almost entirely on prompt visibility.
Treats AI visibility as an additional search layer rather than abandoning traditional SEO.
Organises information so important answers can be extracted more easily.
Targets appearances inside ChatGPT, Gemini, Perplexity and Google AI Overviews.
Ideal for: Singapore SMEs that want GEO incorporated into an existing SEO and website strategy rather than handled as a completely separate specialist engagement.
OC Digital has one of the broader publicly documented GEO service scopes among the agencies on this list.
Its service includes semantic SEO, entity optimisation, technical SEO, AI citation optimisation, structured data, Knowledge Graph work, conversational content, topic clusters, internal linking, FAQ optimisation, E-E-A-T and AI-ready website architecture.
Its work can involve Organisation, Service, Person, Product and LocalBusiness schema, together with brand consistency and entity relationships that help machines establish how a company, its people, services and products connect.
Builds topical and contextual relationships instead of relying primarily on repeated keywords.
Strengthens relationships between the organisation, people, products, services and other recognised entities.
Lists Organisation, Service, Person, Product, Article, LocalBusiness and other schema types.
Ideal for: Businesses that want a technically broad GEO campaign with substantial attention given to semantics, structured data, entity relationships and website architecture.
2Stallions takes a broader “SEO Everywhere” approach in which generative search is incorporated into its existing SEO strategy.
The agency explicitly provides GEO for tools such as ChatGPT, together with AIO for Google’s AI Overviews and AEO for answer engines. Its current service includes structuring pages for AI consumption, improving schema markup and ensuring websites remain accessible and understandable to both conventional crawlers and AI-powered discovery systems.
2Stallions also provides a free 60-second AI-readiness audit that assesses factors such as site speed, structured data and content clarity to highlight whether a website is well positioned for AI search.
Extends conventional optimisation across Google, AI Overviews and generative platforms.
Explicitly works on both Generative Engine Optimisation and Google AI Overview visibility.
Adjusts content structures and schema to make information easier for generative platforms to interpret.
Ideal for: Companies that want one search programme covering traditional Google results, AI Overviews and generative platforms rather than engaging a separate GEO-only consultancy.
Geolix.ai is one of the most specialised companies on this list because GEO is its core business, rather than one service within a larger digital marketing agency.
The Singapore-headquartered company specialises in cross-border GEO, including finance, technology, SaaS, education and healthcare brands operating across Singapore, Hong Kong, Greater China, APAC and international markets.
Geolix says its monitoring system spans nine AI search surfaces, including ChatGPT, Gemini, Perplexity, Google AI Overviews and Google AI Mode as well as Chinese platforms DeepSeek, Doubao, Qwen and Tencent Yuanbao.
Geolix also publishes its own client outcomes, including a finance-sector education brand that reportedly increased targeted-intent visibility from 20% to 80%, a B2B SaaS client moving from 0% to 50% in one month, and two US technology brands exceeding 80% visibility within two months.
Covers both major Western and Chinese generative search ecosystems.
Built specifically for companies expanding into multiple markets rather than Singapore visibility alone.
Tracks brand mentions, citations, competitors and AI visibility using its own monitoring platform.
Ideal for: B2B, fintech, SaaS and regional companies that need measurable GEO visibility across both English-language and Chinese AI platforms.
Upscaled approaches GEO through AI SEO, with a strong emphasis on measuring what AI platforms are already saying before making changes.
Its AI visibility audit tests real buyer questions against ChatGPT, Gemini, Perplexity and Google AI Overviews, recording whether the client’s brand or a competitor appears. Its optimisation work can then cover entity and schema improvements, answer-first content and ongoing citation tracking.
The agency also explicitly warns against guaranteed AI citations, arguing that GEO should instead be measured through movements in citations, brand mentions and AI-referred traffic. For reporting, it references measures such as share of answer, competitor mentions and tools including Ahrefs Brand Radar.
Tests the real conversational questions potential customers may ask AI platforms.
Clarifies brands, services and locations through consistent entities and structured data.
Structures individual passages so they can stand alone as clear, attributable answers.
Ideal for: Businesses wanting a practical AI SEO programme built around baseline measurement, content, entity clarity and ongoing citation tracking.
A Generative Engine Optimisation agency helps businesses increase their likelihood of being understood, mentioned or cited within AI-generated answers.
GEO focuses on whether AI systems can understand a business and use its information when generating an answer. The success metric may therefore be an AI citation or brand mention rather than a traditional Google ranking.
Most Singapore GEO agencies currently focus on ChatGPT, Google AI Overviews, Gemini and Perplexity.
Some extend further. Geolix.ai, for example, states that its platform monitors nine AI surfaces, including DeepSeek, Doubao, Qwen and Tencent Yuanbao for companies targeting Chinese-speaking markets.
No credible GEO agency can guarantee a particular citation, recommendation or position in an AI-generated answer.
Generative platforms continually change their models, retrieval methods and source selection. Businesses should therefore be cautious of agencies guaranteeing permanent ChatGPT rankings or specific AI recommendations.
Compare its AI visibility audit process, external citation work, platforms monitored and how AI visibility is actually measured.
Businesses should also ask to see real-time prompts and AI responses rather than relying only on screenshots or general SEO traffic figures, always asking them to open incognito for ChatGPT.
Absolutely, many GEO strategies rely on the same foundations that support traditional organic search, including technically accessible websites, strong content, clear entity signals and external authority.
