First, what is GEO?
GEO stands for generative engine optimisation. That sounds more complicated than it is. A buyer asks ChatGPT, Google AI Mode, Gemini or another answer engine a question. The system gathers information, writes a response and may name or cite businesses. GEO is the work of making your information useful enough, clear enough and trustworthy enough to be part of that answer.
The important word is not engine. It is answer. You are helping a person get a reliable answer to a real buying question. If the page only repeats keywords or talks around the subject, it is weak for the person and weak for the system summarising it.
GEO is not a magic file or a prompt hack.
There is no switch that makes an AI recommend your company. An llms.txt file can describe useful routes, and structured data can make facts less ambiguous, but neither creates reputation. Engines can compare your own claims with your website, directories, reviews, articles, client references and other independent sources.
This is why the basics still matter: one clear business identity, service pages that answer obvious questions, accurate contact details, crawlable pages, real proof and sources that exist outside your own domain. GEO adds a new answer surface. It does not remove the need for a good website or honest authority.
How a real business uses GEO.
Imagine a buyer asking, who is a good web design agency in Bangkok, what should a website cost in Thailand, or which company can connect AI to our operations. A practical GEO programme starts with those questions. It records the current answers, which companies appear, which sources are cited and whether the answer completed successfully.
Then the business fills the gap. If no page directly owns the service, create one. If the price question is unanswered, publish a sourced cost guide. If the engine cannot verify the company, improve independent profiles and earn relevant references. If the answer reaches the site but the visitor cannot decide, connect it to proof, pricing and a useful contact path.
- Choose ten to twenty questions a real buyer asks before contacting you.
- Separate discovery questions from prompts that already contain your brand name.
- Record complete answers, named businesses and citations on a fixed date.
- Mark broken or incomplete captures invalid instead of counting them as zero.
- Turn the gaps into pages, evidence, profiles and relationships.
- Repeat the same eligible panel and connect referred visits to enquiries.
What content works for GEO?
Useful GEO content helps someone make a decision. Clear definitions are good. Sourced comparison tables are better. Original benchmarks, calculators, checklists and case studies can be stronger because another writer or answer engine has a reason to cite them. The format should match the question, not a weekly publishing quota.
A strong page states the short answer early, explains the method, shows the date, links to primary sources and names its limits. It also has a human next step. A buyer should not reach the end of a detailed guide and wonder what the company actually does.
How do you know if GEO is working?
Do not use one screenshot as a ranking report. AI answers can vary by engine, account, location and time. Use a fixed prompt panel and measure valid answers, brand mentions and citations by engine. Keep engine failures out of the denominator. Then measure referred visits, relevant page engagement and enquiries separately.
A citation is evidence of visibility, not evidence of revenue. The useful chain is question, valid answer, mention or citation, visit, enquiry, qualified opportunity. Most teams cannot see that whole chain on day one. Building it is part of the work.
Where should you start this week?
Write down the five questions your best customer asks before choosing a supplier. Ask two answer engines those exact questions. Save the complete answers and sources. Check whether your company is absent because the information is missing, unclear or unsupported. Fix the smallest real gap first.
For DLVX, that meant publishing a clear Bangkok digital marketing page, a sourced Thailand website cost index, an AI visibility benchmark with an invalid run policy, and decision tools people can use without giving us an email address. GEO becomes concrete when it produces assets a buyer would want even if AI search did not exist.
