An AI SEO agency optimizes your visibility in two places at once: traditional search engines like Google, and AI answer engines like ChatGPT and Google AI Overviews. A conventional SEO agency stops at Google rankings. Novastacks runs both as one practice, because the same content, structure, and authority signals increasingly feed both.
SEO (Search Engine Optimization) earns you rankings and clicks in Google's results. AEO (Answer Engine Optimization) earns you citations and recommendations inside AI-generated answers. SEO optimizes for the ten blue links; AEO optimizes for the moment ChatGPT or an AI Overview names a brand. You need both, and they reinforce each other.
AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) both make your content visible to AI-driven search, but they differ in focus. AEO targets direct, concise answers, such as voice search and featured snippets. GEO optimizes for comprehensive, authoritative content that AI models summarize and cite. Both matter, and they work best together.
Look for three things: senior operators who actually run your account rather than juniors, transparency about who does the work, and a methodology that covers AI search and not just Google. Ask any agency how they will get you cited by ChatGPT and Gemini. If they have no clear answer, they are optimizing for a shrinking slice of search.
Engage one when organic search is, or should be, a meaningful channel for you and you do not have senior in-house SEO capacity. For AEO specifically, earlier is better: AI answer engines are still forming their view of most brands, so there is a first-mover window to become the cited source in your category before competitors do.
AI answer engines pull from structured, authoritative, clearly formatted content. We add FAQ and Q&A structured data, build comparison and use-case pages that directly answer buyer questions, strengthen author and brand credentials, and surface citeable data. We then track which prompts cite you and refine from there. In one recent engagement this took a logistics SaaS from zero to 43 AI citations in 60 days.
Two things. First, we run SEO, AEO, and GEO as one system, so your Google rankings and AI citations compound together instead of being treated as separate projects. Second, senior operators run your account, with experience at Tencent, Expedia, and Klook and a Google Product Expert leading AEO, backed by an AI agent team that scales execution. You get senior judgment and high output, not a junior with a checklist.

Yes. We are Singapore based and know this market deeply, but we also work with APAC companies and businesses in other markets and industry segments such as SaaS, financial, OTA, e-commerce, and more. AEO and GEO are global by nature: if your buyers ask AI about your category anywhere, we can help you become the cited answer.
