Think about the last time you needed a recommendation. Maybe you asked ChatGPT “What’s the best marketing agency in Singapore?” or watched Google answer your question with an AI-generated summary before you even clicked a link.
Your customers are doing the same thing — and if your brand doesn’t show up in those AI-generated answers, you’re invisible to a fast-growing audience.
This is where GEO comes in.
GEO, Explained Simply
GEO stands for Generative Engine Optimisation. It’s the practice of optimising your brand’s online presence so that AI platforms — ChatGPT, Google Gemini, Perplexity, Microsoft Copilot, and Google AI Overviews — recommend your business when users ask for suggestions.
Here’s the key difference from traditional search: when someone Googles a question, they see 10 blue links and choose which to click. When someone asks ChatGPT the same question, they get a direct answer that names 3-4 specific brands. No list of 10. No page 2. Just a handful of recommended businesses.
GEO is how you become one of those 3-4 brands.
The Terminology — GEO, LLMO, AEO, AIO
The industry hasn’t settled on a single name yet. You’ll see several terms floating around, but they all describe the same discipline:
- GEO (Generative Engine Optimisation) — the most widely used term, and the one gaining the most traction
- LLMO (Large Language Model Optimisation) — focuses on the LLM technology angle
- AEO (Answer Engine Optimisation) — frames it around AI being an “answer engine”
- AIO (AI Overview Optimisation) — specifically targets Google’s AI Overviews feature
For simplicity, we use GEO. It covers all AI platforms, not just one. If you want to dive deeper into LLMO specifically, see our LLMO services page.
How GEO Differs from SEO
This is the most important distinction to understand. GEO and SEO are not the same thing — and doing one well doesn’t guarantee success at the other.
| Traditional SEO | GEO | |
|---|---|---|
| Goal | Rank higher in search results | Be the brand AI names in its answer |
| Competition | 10 blue links per page | 3-4 brands per answer |
| What you optimise | Keywords, backlinks, page speed | Entity clarity, structured data, third-party mentions |
| Content style | Keyword-rich, long-form | Fact-dense, Q&A format, comparison tables |
| Authority signals | Domain authority, backlinks | Reviews, directory listings, expert publications |
| Freshness | Nice to have | Critical — 7-14 day refresh cycle |
| Measurement | Rankings, traffic, CTR | Citation rate, brand visibility, share of voice |
| Timeline | 3-6 months for results | 30-90 days for measurable citation changes |
Here’s the stat that makes this real: the overlap between top Google links and AI-cited sources has dropped below 20% and continues to fall. You can rank #1 on Google for a keyword and still not be mentioned by ChatGPT, Gemini, or Perplexity.
They’re fundamentally different systems that require different optimisation strategies.
GEO Doesn’t Replace SEO — It Complements It
Think of it this way:
- SEO is your storefront. It gets people to your door when they search on Google.
- GEO is word-of-mouth. It gets AI to recommend you before people even start browsing.
You need both. A strong SEO foundation actually helps your GEO performance — well-structured websites with good schema markup give AI models more to work with. But SEO alone is no longer enough.
The businesses that will win are the ones that optimise for both traditional search and AI recommendations.
What Makes AI Recommend One Brand Over Another?
AI models don’t rank websites the way Google does. Instead, they assess:
-
Entity clarity — Does AI understand who you are, what you do, and where you operate? Structured data (JSON-LD schema markup) makes this explicit.
-
Content extractability — Can AI easily pull a clear, quotable answer from your content? Pages with Q&A format, comparison tables, and fact-dense paragraphs get cited. Fluffy marketing copy doesn’t.
-
Third-party credibility — Do other trusted sources mention you? AI models look at review platforms, industry directories, press coverage, and expert publications to assess whether you’re credible enough to recommend.
-
Freshness — Is your content up to date? AI engines heavily weight freshness signals. Content that hasn’t been updated in weeks loses citation priority.
-
Consistency — Is your brand information consistent across your website, Google Business Profile, directories, and social media? Conflicting information confuses AI models.
Why This Matters Right Now
The shift to AI search isn’t a future prediction — it’s happening today:
- Google search volume is projected to drop 25% by 2026 (Gartner)
- 48% of Google searches now trigger AI Overviews (BrightEdge)
- ChatGPT has over 800 million weekly active users (DemandSage)
- 60.9% of Singaporeans already use generative AI — the second highest adoption rate in the world
And here’s the opportunity: only 47% of brands have a GEO strategy. Most of your competitors are not yet optimising for AI search. The window for first-mover advantage is right now.
What Can You Do Today?
If you’re just learning about GEO, here are three things you can check immediately:
-
Ask ChatGPT about your industry. Type “What’s the best [your industry] in Singapore?” and see if your brand appears. Try the same on Gemini and Perplexity. If you’re absent, that’s your baseline.
-
Check your schema markup. Go to Google’s Rich Results Test and enter your website URL. If you don’t see Organization, LocalBusiness, or FAQ schema, you’re missing the structured data AI needs.
-
Google your brand name + “reviews”. If nothing comes up — no Google Reviews, no Clutch profile, no directory listings — AI has no third-party signals to assess your credibility.
These three checks will tell you exactly where you stand.
