# Novastacks > Novastacks is an AI search agency based in Singapore. It gets scale up startups, enterprises and known brands found in Google and named in ChatGPT, Gemini, Perplexity and Google AI Overviews, through SEO, AEO (answer engine optimisation) and GEO (generative engine optimisation). Clients are served across Southeast Asia, Greater China, Australia, the United Kingdom and the United States. Senior principals run every account; there are no account managers. They direct Novastacks AI Search OS, a proprietary agentic system of specialised Claude Code agents for research, content, technical implementation and performance analysis. The system has four layers: Data, Decision, Execution and Measurement. Engagements run in a repeating loop of Audit, Architect, Activate and Amplify. Results are reported as citations, share of answer, non brand demand and pipeline, per market. Novastacks offers four kinds of work: AI SEO, AEO and GEO (Search); agentic marketing training and advisory (Train); AI marketing systems built for and owned by the client (Build); and fractional growth leadership (Grow). Enquiries are answered within 2 to 4 hours, 9 AM to 6 PM SGT, Monday to Friday. ## Services - [AEO services](https://www.novastacks-ai.com/aeo): answer engine optimisation in Singapore, getting a brand cited and recommended by ChatGPT and Google AI Overviews - [GEO services](https://www.novastacks-ai.com/geo): generative engine optimisation, getting a brand recommended by ChatGPT, Gemini and Google AI Overviews - [Technical SEO services](https://www.novastacks-ai.com/technical-seo-singapore): crawl, rendering and indexing audits, sitemaps, IndexNow and Core Web Vitals - [International and multilingual SEO services](https://www.novastacks-ai.com/international-seo-singapore): site structure, hreflang, market setup and content for brands across Asia Pacific - [Local SEO services](https://www.novastacks-ai.com/local-seo-singapore): Google Business Profile, reviews, map results and consistent business details - [Enterprise SEO in Singapore](https://www.novastacks-ai.com/enterprise-seo-singapore): scope, cost bands and how to choose an agency for large sites - [AI SEO in Singapore](https://www.novastacks-ai.com/ai-seo-singapore): guide for CMOs and owners on AI visibility, market retainers and timelines - [Agentic AI advisory](https://www.novastacks-ai.com/agentic-advisory): advice on designing and adopting agentic AI workflows that hold up in production - [Claude Code workshop](https://www.novastacks-ai.com/workshop): a 4 hour hands on course for marketing and sales teams, no coding required, 25 seats - [Fractional growth partner](https://www.novastacks-ai.com/fractional-growth-partner): senior marketing leadership from Expedia, Tencent and Klook veterans, backed by AI agents - [Fractional CMO in Singapore](https://www.novastacks-ai.com/fractional-cmo-singapore): how to choose the right type of fractional CMO ## Industries - [All industries](https://www.novastacks-ai.com/industries): index of industry pages - [Ecommerce](https://www.novastacks-ai.com/industries/ecommerce): rank a store on Google and get products recommended by ChatGPT and Gemini - [AEO for ecommerce](https://www.novastacks-ai.com/aeo-for-ecommerce): getting products recommended when shoppers ask AI what to buy, with UCP and ACP readiness - [Healthcare](https://www.novastacks-ai.com/industries/healthcare): helping patients find doctors and clinics on Google and in AI answers - [AEO for healthcare](https://www.novastacks-ai.com/aeo-for-healthcare): 2026 playbook for clinics, dental, aesthetic and supplement brands, based on 6 published audits - [B2B](https://www.novastacks-ai.com/industries/b2b): turning buyer research on Google and ChatGPT into qualified pipeline - [SaaS](https://www.novastacks-ai.com/industries/saas): getting cited when buyers ask ChatGPT for the best software in a category - [AEO for SaaS](https://www.novastacks-ai.com/aeo-for-saas): a 60 day playbook, tools and pricing - [Hotels and travel](https://www.novastacks-ai.com/industries/hotels): direct bookings from Google search and AI travel answers - [Financial services](https://www.novastacks-ai.com/industries/financial-services): costs, keywords and agency criteria for financial services SEO in Singapore - [Law firms](https://www.novastacks-ai.com/industries/law-firms): AEO, GEO and SEO for law practices in Singapore - [Real estate](https://www.novastacks-ai.com/industries/real-estate): agencies and listings on Google and in AI property answers - [Education](https://www.novastacks-ai.com/industries/education): schools, universities and course providers on Google and in AI answers - [Logistics and supply chain](https://www.novastacks-ai.com/industries/logistics): logistics, freight and supply chain companies on Google and in AI answers - [Gaming and digital marketplaces](https://www.novastacks-ai.com/industries/gaming): product searches and AI answers in Singapore and Southeast Asia ## Case studies - [All case studies](https://www.novastacks-ai.com/case-studies): index of published client results - [GoFreight](https://www.novastacks-ai.com/case-studies/saas-website-migration-ai-visibility): freight software;
