AEO and AI Search: Get Cited in ChatGPT and Google AI

The way customers find businesses is shifting under everyone's feet. A Bangkok client recently told us that 18% of his new patient inquiries last quarter started with "ChatGPT recommended you." That number was zero a year earlier. The same pattern is showing up across hotels, law firms, schools, and service businesses across Thailand. AI search is real, it is here, and most companies have no plan for it.

This is where AEO (Answer Engine Optimization) comes in. AEO is the practice of making sure your business is visible, quotable, and recommended inside ChatGPT, Perplexity, Google AI Overviews, Gemini, and the next wave of AI search tools. It is not optional anymore. It is the new layer of the search game.

AEO vs SEO vs GEO: What Is Actually Different

The acronyms multiply, so let us cut through them:

• SEO targets traditional search engines: ranking your pages on Google's blue links.
• GEO (Generative Engine Optimization) targets the same content layer but with the goal of being cited inside AI-generated answers.
• AEO (Answer Engine Optimization) is the broader category: optimizing for any system that generates direct answers, including AI tools, voice assistants, and Google's own AI Overviews.

In practice, the work overlaps heavily. Strong SEO foundations support AEO. But AEO requires specific tactics that traditional SEO never optimized for, because AI engines do not rank — they answer.

How AI Search Engines Decide What to Recommend

AI tools do not crawl and rank pages the same way Google does. They use a mix of signals that are partly familiar and partly new:

• Training data: what they were trained on, including web content, structured data, and reputable sources up to their cutoff date.
• Live retrieval: when a question is asked, many AI tools now search the web in real time and pull from indexed pages.
• Authority signals: how often a brand is mentioned across trusted sources, what the sentiment of those mentions looks like, whether the brand has structured information that can be extracted cleanly.
• Schema and structured data: AI tools strongly prefer pages where structured data tells them exactly what the business is, what it offers, where it operates.

The implication is significant: a business with strong brand mentions, clean structured data, and quotable content can be cited by AI even without ranking number one on Google.

The Type of Content AI Tools Quote Most Often

After analyzing what AI search engines pull from for service-business queries in Thailand, a clear pattern emerges. The content most likely to be cited shares these traits:

• Clear, factual answers at the top of the page, not buried under three paragraphs of warm-up.
• Bulleted or numbered lists with concrete details (prices, timelines, specifics), not vague statements.
• FAQ-style sections answering exactly the kind of questions users would ask.
• Defined scope: the geographic, industry, or service boundary is stated clearly.
• Evidence: a specific number, a verifiable fact, a real example. Not "many businesses." Concrete.

If your content reads like an AI tool could quote a sentence and have it stand on its own, you are on the right track.

Schema Markup, Structured Data, and Why AI Reads It First

Schema markup is the JSON-LD or microdata you add to a page that tells search engines exactly what the page is about. AI search engines depend on it heavily because it removes ambiguity.

For a Bangkok service business, the schema types worth implementing include:

• LocalBusiness with full NAP, geo coordinates, opening hours, and area served.
• Organization for brand-level identity, including logo and same-as links to social profiles.
• Service entries for each major service offered.
• FAQPage for FAQ sections.
• Article or BlogPosting for content pages.
• Review and AggregateRating where appropriate.

Schema is invisible to your visitors. To AI engines and Google's AI Overviews, it is the first thing they read.

Brand Mentions: The Hidden Currency of AI Visibility

One of the biggest differences between SEO and AEO is the role of pure brand mentions. In traditional SEO, a mention without a link has limited weight. In AEO, brand mentions across trusted sources are critical because they tell AI tools that your brand is recognized.

What counts:

• Industry publications mentioning your business by name.
• News articles, partner blogs, and trade press citing you as a source or example.
• Forum and community discussions referencing you (genuinely, not paid).
• Podcast features and interviews.
• Reviews on platforms beyond Google (Wongnai, TripAdvisor, industry-specific review sites).

The volume matters less than the breadth. AI tools that see your brand mentioned across many independent, credible contexts are far more likely to recommend you.

How to Audit Whether AI Already Knows Your Business

Before optimizing, find out where you stand. Three quick checks:

1. Ask the AI directly. Open ChatGPT, Perplexity, and Google's AI mode. Ask the question your customers would ask: "Best dentist in Sukhumvit," "Top Bangkok law firm for expats," "Recommended SEO agency Bangkok." See if you appear, who else appears, and how you are described.
2. Check your structured data. Run your homepage and key service pages through Google's Rich Results Test. Missing or broken schema is a fixable AEO issue.
3. Count your mentions. Search "your brand name" in quotes on Google. The volume and quality of pages that mention you set your AI visibility ceiling.

AEO Tactics That Work for Bangkok Service Businesses

The tactics that move the needle in Bangkok markets:

• Build entity clarity. Your brand should have a clean Wikipedia, Wikidata, or LinkedIn presence with consistent description and same-as links.
• Publish answer-style content. Pages built around real customer questions, with clear, factual answers near the top.
• Implement complete schema across services, locations, and FAQs.
• Earn diverse mentions. Industry publications, local news, partner blogs, podcast features. Volume across sources beats volume on one source.
• Strengthen reviews on platforms beyond Google. Wongnai, TripAdvisor, and industry-specific review sites all feed into AI tool perceptions.
• Stay consistent across languages. Bangkok runs in Thai and English. AEO needs both versions to capture both audiences.

How Novotize Builds AI Visibility for Clients

Our AEO work follows a tight sequence: audit current AI visibility, fix structured data foundations, expand answer-style content, and build a consistent stream of brand mentions across credible sources. Each step is measured by checking the actual outputs of the major AI tools every two weeks. If we are not changing what AI says about a client, the work is not working.

The result is not a vanity ranking but a clear shift in how AI describes the brand and how often it appears in recommendation lists.

AEO is not a feature you bolt onto SEO. It is the search layer where customers will look first within two years. The work has to start now.

AEO Action Checklist

1. Run an AI visibility check on ChatGPT, Perplexity, and Google AI Overviews for your top five customer queries.
2. Audit and fix schema markup on homepage, service pages, and key blog content.
3. Restructure two or three top pages around clear, factual answers near the top.
4. Add an FAQ section with FAQPage schema on key service pages.
5. Publish at least one in-depth answer-style article per month.
6. Build a list of target sites for brand mentions and start outreach.
7. Re-run the AI visibility check every 60 days and track shifts.
