Schema and structure AI can parse
Correct Schema.org markup, headings that answer a real question, and an answer above the fold so ChatGPT, Gemini and Perplexity can lift it without guessing.
Structured data, entity signals and answer-shaped content so your business shows up in ChatGPT, Gemini, Perplexity and Google AI Overviews — on a site that loads in milliseconds, with a monthly report you can actually read.

Short answer
GEO (generative engine optimisation) is the work of getting your business quoted inside AI answers — ChatGPT, Gemini, Perplexity and Google AI Overviews — rather than only ranking in the blue links. WebSiam's GEO service starts at ฿6,900/month with a 3-month minimum, a monthly report, and every task done by hand.
people in Thailand use the internet — 94.7% of the population, so your customers are already there.

DataReportal × Kepios — Digital 2026: Thailand (Oct 2025 data)Buyers increasingly ask an AI instead of working through ten blue links. If ChatGPT or Google AI Overviews has never heard of your business, you simply are not in that conversation. GEO is not an old SEO package with the word AI bolted on — it is fixing the structure of your site, your entity signals and the shape of your answers so those engines can quote you.
We do every step in-house, with a written scope rather than a one-size-fits-all template. Work starts at ฿6,900/month on a 3-month minimum, because entity and content work needs time to compound — and you get a monthly report on what actually moved.

AI wants to know who you are before it quotes you. We align your business name, address, LINE handle, social profiles and third-party mentions across every surface.
We collect the questions your customers actually ask and write a direct answer under each heading — the format answer engines quote most often.
Brick-and-mortar businesses need Maps and location-anchored answers too. We keep your site and Google Business Profile saying the same thing.
Most Thai search happens in Thai, while AI answers across languages. We cover both without duplicating pages into a near-copy Google has to choose between.
Slow sites with messy structure get filtered out by both Google and AI. WebSiam sites are built on a modern stack and load in milliseconds from day one.
GEO stands for Generative Engine Optimization: getting your business mentioned when someone asks ChatGPT, Gemini, Claude, Perplexity or Google AI Overviews. Unlike SEO there is no 1-10 ranking — you are either quoted in a single answer or you are absent, and there is far less room. Getting in requires self-contained answers, credible entity signals and markup a machine can read. The full breakdown lives in our guide to GEO, AEO and MEO pricing
The three terms get used interchangeably, but they do different jobs. GEO covers being quoted in generated summaries, AEO covers having your question answered exactly, and MEO covers answers tied to a place, such as “coffee shop near me”. Thai businesses with a physical location need all three, so we run them together in one engagement.

Straight answer: GEO work starts at ฿6,900/month with a 3-month minimum, and it is the same engagement as our Local SEO service, because the structure, entity signals and content an AI quotes all have to sit on a good website to begin with.
Months one to three are foundation work: Schema, the questions your customers ask, and business data consistent everywhere. From month three to six you start seeing your brand appear inside answers, then it compounds. We do not guarantee rankings — nobody honestly can. We promise white-hat work, a written scope, and a monthly report in plain language.
From ฿6,900/month with a 3-month minimum, in the same engagement as our Local SEO service, because both depend on site quality and trust signals. Full package pricing is on the pricing page and there are no hidden line items.
SEO is where your page ranks in the results; GEO is whether your name is quoted inside the answer an AI writes. They work best together and share the same foundation: site structure, speed and credibility.
Foundation work is done in months one to three; consistent citation usually becomes visible between months three and six, depending on content quality and competitors in your category. That is why we set a 3-month minimum and say so before you sign.
Nobody can promise that — ChatGPT picks its own sources and changes them constantly. What we can do is raise the odds with self-contained answers, easy-to-parse structure and consistent trust signals. Be sceptical of anyone guaranteeing citation or rank.
GEO alone is possible but poor value, since both share the same groundwork. Most clients start both under one agreement. If budget is tight, start with the pages that make money and expand later.
