You may have seen three similar terms: SEO, AEO and GEO. If you run a Singapore business, the practical question is simple: do these need three separate projects? Mostly no. Here is how they fit together.
The Short Answer
AEO and GEO are two names for the same job. Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO) both mean getting your business named and cited inside AI answers. SEO is the older discipline of ranking pages in Google results, and it shares the same foundations.
The Three Terms Explained
SEO
Search Engine Optimisation. Gets your pages ranked in Google so searchers click through to your site.
AEO
Answer Engine Optimisation. Gets your business chosen as the answer when someone asks an AI assistant or answer box.
GEO
Generative Engine Optimisation. The same goal, aimed at generative AI tools that write answers, such as ChatGPT, Perplexity, Gemini and Google AI Overviews.
Why Two Names Exist
AEO is the older label and is often linked to answer boxes and voice assistants. GEO became popular as generative AI tools took off. Marketers use them interchangeably, and the work behind both is the same. Americans spell them Answer Engine Optimization and Generative Engine Optimization, which is why you will see both spellings in searches.
What the Work Looks Like
Answer-first pages
Put the direct answer in the first two lines of each page, then add an FAQ with real customer questions.
Schema and llms.txt
Add FAQ, Service and business markup, and publish an llms.txt file so AI tools can read your site.
Third-party proof
Complete listings on Clutch, Sortlist, GoodFirms and DesignRush, collect Google reviews and answer questions in communities. AI tools trust what many sources say about you.
Test real prompts
Ask ChatGPT, Perplexity and Gemini the questions your customers ask, record who is named, and re-test every month.
Do You Need All Three?
If customers search for what you sell, you need SEO. If customers ask AI for recommendations, you need AEO and GEO, which is one programme. In 2026 both are true for most service businesses in Singapore. The work overlaps, so one strong service page with direct answers and FAQ markup helps you rank and helps AI quote you.
Start here: ask ChatGPT and Perplexity "best [your service] in Singapore". If you are not named, that is your AEO and GEO gap.
