SEO and GEO in 2026: how a small business in Singapore or Malaysia gets found on Google and in AI answers
By Nikka, Founder, Jabbibi · Published · 22 min read
Crawler names, platform features and figures checked against Google, OpenAI, Perplexity, Anthropic and Microsoft documentation on 19 September 2026.

When a customer in Singapore or Johor Bahru looks for a supplier in 2026, they often never see a list of ten blue links. Google answers with an AI Overview, or they ask ChatGPT, Perplexity or Copilot and get a short answer with two or three sources. This guide explains what it takes for your business to be one of those sources, and why almost all of it is still ordinary, well-done SEO.
Short answer
SEO (search engine optimisation) gets your pages ranked in Google and Bing. GEO (generative engine optimisation) gets your pages quoted and cited in AI answers from Google AI Overviews, ChatGPT, Perplexity and Microsoft Copilot. For a small business they are one job, not two.
- Google states there are no extra requirements to appear in AI Overviews or AI Mode: a page must be indexed and eligible to show a snippet, though that does not guarantee it will be shown (Google Search Central).
- ChatGPT search and Perplexity use their own crawlers, OAI-SearchBot and PerplexityBot. If your robots.txt or your host's firewall blocks them, you will not be cited in their search answers.
- What gets a passage quoted is content that answers the question in its first sentence, names who and where, and backs its claims with figures and sources. In the 2023 GEO study (published at KDD 2024), adding quotations, statistics and citations raised visibility in AI answers by up to 40%; keyword stuffing did not help.
Key takeaways
- You do not need an AI text file, special markup or a new schema type to appear in Google's AI features. Google says so in writing.
- Blocking AI training is not the same as blocking AI search. You can disallow GPTBot and still be cited in ChatGPT search. Disallowing Google-Extended keeps you in Google Search, but also keeps your pages out of answers in the Gemini app.
- Google stopped showing FAQ rich results on 7 May 2026 (Google Search Central). FAQ sections are still worth writing, because AI answers quote them, but not for the rich result.
- Microsoft's Bing Webmaster Tools has reported Copilot citations per page since February 2026, as a free public preview (Bing Webmaster Blog).
- For a local business, in our experience a complete Google Business Profile with steady reviews still does more than any GEO tactic. Google says local results are mainly based on relevance, distance and prominence.
What SEO and GEO actually mean
Search engine optimisation (SEO) is the work of making your web pages easy for search engines to crawl, understand and rank for the searches your customers type. Generative engine optimisation (GEO) is the work of making those same pages easy for AI assistants to retrieve, quote and cite when they write an answer. The term GEO comes from a 2023 research paper led by researchers at Princeton University and published at the KDD 2024 conference (Aggarwal et al.).
The difference is in what winning looks like. In SEO, you win a position in a list and hope for the click. In GEO, you win a sentence inside an answer, usually with a small link to your page next to it.
| SEO | GEO | |
|---|---|---|
| Where you appear | Google and Bing results pages, Google Maps | Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Microsoft Copilot, Gemini |
| Unit that wins | A whole page | A passage: a paragraph, a table row, a list item |
| What it rewards | Relevance, links, a page that satisfies the search | A clear, self-contained answer with evidence the AI can repeat safely |
| How you measure it | Rankings, clicks and impressions in Google Search Console | Citations in Bing Webmaster Tools, AI referrals in Google Analytics, and asking the assistants yourself |
| Can it work without the other? | Yes | Rarely. AI search features retrieve from a search index first |
What changed, and what did not
What changed is where the click goes. In a Pew Research Center study of 900 US adults' Google searches in March 2025, users who saw an AI summary clicked a traditional result in 8% of visits, against 15% for users who did not see one. They clicked a link inside the summary itself in only 1% of visits (Pew Research Center, 22 July 2025). That is US data, but the lesson applies here too: when the answer sits on the results page, fewer people visit any website, so being named inside the answer matters more, even though few readers click through from it.
What did not change is how you get into the answer. Google's own documentation on AI Overviews and AI Mode says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." It adds that you do not need new machine-readable files, AI text files or special schema.org markup (Google Search Central, updated 10 December 2025). The page must be indexed and eligible to be shown with a snippet. That is the same bar as ordinary search.
The practical meaning: anyone selling you a "GEO package" that ignores your indexing, your page speed and your Google Business Profile is selling the roof before the walls.
How each AI engine finds your pages
Every AI assistant that cites sources has to fetch pages from somewhere. Most of them use a search index, either their own or a partner's, and each has a crawler you can allow or block by name in robots.txt.
| AI answer engine | Crawler that decides whether you can be cited | What to do |
|---|---|---|
| Google AI Overviews and AI Mode | Googlebot, the same crawler as Google Search | Get indexed in Google Search. Check Search Console's Page indexing report |
| ChatGPT search | OAI-SearchBot. OpenAI says sites that opt out of it "will not be shown in ChatGPT search answers, though can still appear as navigational links" | Allow OAI-SearchBot in robots.txt and in your firewall or CDN bot settings |
| Perplexity | PerplexityBot, which Perplexity says surfaces and links sites in its results and is not used to train foundation models | Allow PerplexityBot |
| Claude (Anthropic) | Claude-SearchBot. Anthropic says blocking it "may reduce your site's visibility and accuracy in user search results" (Anthropic) | Allow Claude-SearchBot |
| Microsoft Copilot and Bing AI summaries | Bingbot, through the Bing index | Verify your site in Bing Webmaster Tools and submit new pages with IndexNow, which Bing and several other engines accept (IndexNow) |
OpenAI also runs ChatGPT-User, which fetches a page when a person asks ChatGPT to open it, and states that it "is not used to determine whether content may appear in Search" (OpenAI, Overview of OpenAI crawlers). Perplexity-User does the same job for Perplexity and, because a person asked for the page, generally ignores robots.txt (Perplexity, Perplexity crawlers).
A common reason a small business is invisible in ChatGPT search is not its content but a security setting. Many hosting plans and CDNs now offer a one-click "block AI bots" setting. Depending on how it is configured, it can block the search crawlers along with the training crawlers. Check it before you rewrite a single page.
Blocking AI training without leaving AI search
Some business owners want to be recommended by AI assistants but do not want their content used to train AI models. That is possible, because the training crawlers and the search crawlers have different names.
- GPTBot collects content for training OpenAI's models. Blocking it does not remove you from ChatGPT search, which uses OAI-SearchBot.
- Google-Extended controls whether content Google crawls may be used to train future Gemini models, and for grounding, which means supplying search results to Gemini at the moment it answers in the Gemini app and on Vertex AI. Google states that it "does not impact a site's inclusion in Google Search nor is it used as a ranking signal" (Google, common crawlers).
Blocking Google-Extended therefore keeps you in Google Search, AI Overviews and AI Mode, which are part of Search, but out of Gemini app answers. A robots.txt that allows AI search, declines AI training and accepts that trade looks like this:
User-agent: GPTBot
Disallow: /
User-agent: Google-Extended
Disallow: /
User-agent: *
Allow: /
Sitemap: https://www.example.com/sitemap.xml
We allow everything on jabbibi.com, training included, because we would rather be understood by every model than protect a marketing site. For a business whose content is the product, such as a course provider or a publisher, the split above is the sensible default. OpenAI notes that robots.txt changes take about 24 hours to reach its search systems (OpenAI).
The SEO foundations AI answers are built on
Because AI search retrieves from search indexes, the ordinary foundations decide whether you are in the running at all. For a small business in Singapore or Malaysia these are the ones that matter most.
One page per service, per place
A single "Services" page that lists everything you do gives a search engine, and an AI, nothing specific to quote. Give each service its own page, and give each location you serve its own page when the offer or the proof differs. "Pastry courses in Johor Bahru" and "weekend baking classes for Singaporeans in JB" are different searches with different customers, and each deserves a page that answers it directly.
Titles and descriptions that state the answer
Write each page title as the thing the customer searched for, with the place: "Aircon servicing in Tampines: prices and booking", not "Welcome to ABC Services". Keep titles near 60 characters and meta descriptions near 155, and put a concrete fact in the description, such as a price, a duration or a location.
Crawlable, fast, and readable without JavaScript
- Submit an XML sitemap in Google Search Console and Bing Webmaster Tools.
- Make sure the main text is in the HTML the server sends. Not every AI crawler runs JavaScript, so a page built entirely in the browser can look empty to some of them.
- Keep the page fast on a phone, which is where most of your customers will find you.
- Link related pages to each other with descriptive anchor text, so every important page is reachable in two or three clicks.
Your Google Business Profile
For anything with a shopfront or a service area, the Google Business Profile does more than any page on your site. Google says local results are mainly based on three things: relevance, distance and prominence. It also says that "more reviews and positive ratings can help your business's local ranking", and that businesses with complete and accurate information are more likely to show up (Google Business Profile Help). Choose the most specific primary category, fill in services and opening hours, add real photos, and ask every customer, not only the happy ones, for a review in the same week you finish the job. Our Google Business Profile guide covers setup, verification and the review rules step by step.
Show who is behind the page
Google's guidance on helpful content asks whether it is "self-evident to your visitors who authored your content", and describes trust as the most important part of E-E-A-T, its shorthand for experience, expertise, authoritativeness and trust (Google Search Central). Put a named author on articles, an about page with real people, your registered business name and number, and a physical address or service area. In our experience, AI assistants favour the same kind of clearly attributed source when they choose what to repeat.
Writing passages an AI will quote
An AI answer engine does not quote a page. It quotes a passage: a paragraph, a table row or a list item that still makes sense when lifted out. We aim for paragraphs of 40 to 80 words. The GEO study tested nine ways of rewriting content and found that citing sources, adding quotations and adding statistics worked best, improving visibility by 30% to 40% on the study's main measure. The tests ran on a research engine built on GPT-3.5, and were checked on Perplexity. Keyword stuffing, the oldest SEO trick, gave "little to no improvement" (Aggarwal et al., KDD 2024).
The same study found the effect was largest for pages that ranked lower. Websites ranked fifth in the search results gained 115.1% in visibility from citing sources, while the top-ranked website lost 30.3% on average. For a small business competing with bigger names, we think that is the most encouraging finding in GEO research so far.
Six rules for citable passages
- Answer in the first sentence. Put the direct answer first and the explanation after. Every section of this article opens that way.
- Make each paragraph stand alone. Name the subject instead of writing "it" or "this", because the paragraph may be read without the one before it.
- Say where it applies. Start country-specific facts with "In Singapore," or "In Malaysia," so a quoted sentence cannot be applied to the wrong country.
- Give numbers with units, currency and a date. A line such as "S$180 for a 3-hour class, as at September 2026" (an invented example) is quotable. "Affordable prices" is not.
- Cite your source in the sentence. Link to the government page, the study or the regulator you relied on.
- Use tables for comparisons. Prices, packages and "X vs Y" questions are easier for an AI to extract from a table than from prose.
A rewrite, before and after
Here is a typical paragraph from a small business services page, and a version an AI assistant can actually use. The business and its figures are made up for this example.
Before (fictional example): We are passionate about keeping you cool and offer a wide range of high-quality aircon services at affordable prices. Our experienced team will take care of everything. Contact us today to find out more!
After (fictional example): A chemical wash for one wall-mounted aircon unit costs S$80 with us in Tampines, as at September 2026, and takes about 90 minutes. We recommend one every 12 to 18 months for units that run daily, and a general service every 3 months in between. Bookings open 7 days ahead, and we cover all of Singapore's east side, from Pasir Ris to Bedok.
The second version answers what, where, how much, how long, how often and for whom. An assistant asked "how much is an aircon chemical wash in Tampines" can quote it whole, and name the business while doing so. It is the pattern we use when we rewrite service pages for clients.
Write the FAQ your customers actually ask
People ask AI assistants full questions, such as "is it worth driving to JB for a baking course" or "how much does aircon chemical wash cost in Singapore". A short FAQ at the end of each service page, with each answer in 40 to 80 words, matches that shape exactly. Take the questions from your WhatsApp enquiries and your sales calls, not from a keyword tool.
Structured data in 2026
Structured data is code, usually JSON-LD, that tells machines what a page is about: this is a business, here is its address, this is an article by this person. It still helps search engines understand your site, but two changes in the last three years mean it is no longer a shortcut to a prettier result.
- Google limited FAQ rich results to well-known government and health websites in 2023, then stopped showing them altogether on 7 May 2026 (Google Search Central, documentation updates).
- Google states that no special schema.org structured data is needed to appear in AI Overviews or AI Mode.
What is still worth adding for a small business: Organization or LocalBusiness on the home page, with your address, phone number and links to your social profiles in sameAs; Article or BlogPosting with a named author on articles; BreadcrumbList on deeper pages; and Product or Course where they fit. Keep every value in the markup identical to what the page shows. Leaving existing FAQ markup in place does no harm, since other search engines may still read it.
Do you need an llms.txt file?
No, but it is cheap to add. An llms.txt file is a short Markdown file at the root of your site that summarises what the business does and links to its most important pages. It was proposed by Jeremy Howard in September 2024 "to provide information to help agents use a website" (llmstxt.org).
Be clear about what it does not do. Google says you do not need AI text files to appear in its AI features, and as at September 2026 no major AI search engine has publicly said it ranks or cites pages because of llms.txt. We publish one at jabbibi.com/llms.txt, generated automatically from our page titles and descriptions, because it takes minutes and helps AI agents that do read it. Spend an hour on it, not a week.
Being mentioned where AI looks
In our experience, AI assistants are more likely to recommend businesses they can find described consistently in several independent places. Your own website is one source. News articles, local directories, association member lists, review sites, forums and partners' websites are the others, and in our experience they count for more because you did not write them.
We used this approach for Pastry Art Academy, a pastry school in Johor Bahru. Instead of buying advertising, we offered local media and lifestyle sites a class experience rather than paying for placement, set up referral partnerships with education agents, and wrote course pages and articles with sections built to be quoted. The academy now gets new leads without spending on ads. None of that was a trick: it was ordinary public relations and partnerships, done with AI search in mind.
- Keep your business name, address and phone number identical everywhere: website, Google Business Profile, Facebook, directories.
- Get listed in the directories that matter in your trade, such as a professional body, a trade association or an industry marketplace.
- Answer questions honestly on forums and communities where your customers ask them, as a named person from the business.
- Offer something newsworthy to local media: a free workshop, a survey of your customers, a first in your area.
Singapore and Malaysia specifics
Most GEO advice is written for the US market. A few things work differently here.
In Singapore
In Singapore, many customers search in English, many also read Chinese, and some prefer to ask in it. If your customers include Mandarin speakers, a proper Chinese version of your key pages, linked to the English pages with hreflang tags, can surface you for questions asked in Chinese that English-only competitors never answer (Google, localized versions). Write prices in SGD with the S$ sign, and name the neighbourhood or MRT station you serve, because that is how people in Singapore phrase local questions.
In Malaysia
In Malaysia, customers switch between English, Bahasa Malaysia and Chinese, and search in all three. Decide which languages your customers actually use before translating, and translate the pages that sell, not every page. Write prices in ringgit with the RM sign, and be specific about the city and state, since "Johor Bahru", "JB" and "Iskandar Puteri" are all searched separately. A business that serves customers from both countries should have separate pages for each, with each page stating its currency and the practical details, such as the checkpoint or delivery area, for that side of the Causeway.
WhatsApp is the conversion, so track it
In both countries, in our experience, the enquiry from an AI answer usually arrives as a WhatsApp message, not a form. Put a WhatsApp button on every service page and track clicks on it as a key event in Google Analytics, or you will never know whether your visibility turned into customers. It is how we measure our own site.
Measuring AI visibility
AI visibility is harder to measure than rankings, but it is no longer invisible. Use these four sources together.
| Tool | What it tells you | Limitation |
|---|---|---|
| Bing Webmaster Tools, AI Performance report | How often Copilot and Bing AI summaries cite each of your pages, and the grounding queries behind the citations. Public preview from 10 February 2026; Intents, Topics and Citation Share were added on 16 June 2026 (Bing) | Covers Microsoft's AI experiences and partners only |
| Google Search Console | Clicks and impressions from Google, with AI Overviews and AI Mode counted inside the Web search type (Google) | AI Overview traffic is not reported separately |
| Google Analytics 4 | Visits referred by chatgpt.com, perplexity.ai, copilot.microsoft.com and gemini.google.com. ChatGPT adds utm_source=chatgpt.com to the links it sends (OpenAI) |
Only counts people who click; many read the answer and message you directly |
| Asking the assistants yourself | Whether ChatGPT, Perplexity, Gemini and Copilot name you for the ten questions your customers ask most | Answers vary by user, location and day, so track a trend over months |
Add one more, the oldest one: ask every new customer how they found you, and record "ChatGPT" or "Google's AI answer" as its own option. In our experience it is often the only way to see AI recommendations that never produced a click.
A 30-day plan for a small business
This is the order we work in for clients. Each week builds on the one before, and none of it needs a paid tool.
| Week | Do this |
|---|---|
| Week 1: access | Verify the site in Google Search Console and Bing Webmaster Tools and submit the sitemap. Check robots.txt and your host's bot settings allow Googlebot, Bingbot, OAI-SearchBot, PerplexityBot and Claude-SearchBot. Fix any page that is not indexed |
| Week 2: local | Complete the Google Business Profile: category, services, hours, photos. Make your name, address and phone number identical everywhere. Ask your last 20 customers for a review |
| Week 3: pages | Give each main service its own page. Rewrite the first paragraph of each to answer the question directly, with prices, durations and place. Add a short FAQ from real customer questions, and Organization or LocalBusiness structured data |
| Week 4: proof and tracking | Pitch two local media or partner sites. Set up WhatsApp click tracking and an AI referrals view in Google Analytics. Write down how ChatGPT, Perplexity, Gemini and Copilot answer your top ten questions today, and check again each month |
What a lot of GEO advice gets wrong
| Often said | The current position |
|---|---|
| "GEO replaces SEO" | AI search features retrieve from search indexes. Google requires nothing extra beyond being indexed and snippet-eligible |
| "You need llms.txt to appear in AI answers" | Google says no AI text files are needed. No major AI search engine has publicly said it uses llms.txt for ranking or citation |
| "Add FAQ schema to get rich results" | Google stopped showing FAQ rich results on 7 May 2026. Write the FAQ for readers and AI answers instead |
| "Blocking GPTBot removes you from ChatGPT" | ChatGPT search uses OAI-SearchBot. GPTBot is for model training |
| "AI visibility can't be measured" | Bing Webmaster Tools has reported Copilot citations per page since February 2026 (public preview), and AI referrals show up in Google Analytics |
| "Repeat your keyword more often" | In the GEO study, keyword stuffing gave little to no improvement in AI answers. Statistics, quotations and citations did |
Frequently asked questions
What is GEO in marketing?
GEO, or generative engine optimisation, is the work of making your web pages easy for AI assistants such as ChatGPT, Perplexity, Microsoft Copilot and Google AI Overviews to find, quote and cite in their answers. The term comes from a 2023 Princeton-led research paper, published at KDD 2024. For a small business, GEO is mostly good SEO plus clear, well-sourced, quotable writing.
Is GEO different from SEO?
Partly. SEO aims to rank a whole page in search results; GEO aims to have a passage from that page quoted inside an AI answer. They share the same foundation, because AI search features retrieve pages from search indexes. Google says there are no additional requirements to appear in AI Overviews or AI Mode beyond being indexed and eligible for a snippet.
How do I get my business recommended by ChatGPT?
Allow OAI-SearchBot in your robots.txt and your host's bot settings, because OpenAI says sites that opt out of it will not be shown in ChatGPT search answers, though they can still appear as navigational links. Then publish specific service pages that state prices, locations and durations, keep your business details identical across the web, and earn mentions in local media, directories and reviews.
Do I need an llms.txt file for AI search?
No. Google says you do not need AI text files to appear in AI Overviews or AI Mode, and as at September 2026 no major AI search engine has publicly said it ranks or cites pages because of llms.txt. It is a short Markdown summary of your site, proposed in September 2024, and cheap to add, so add it if you like, but spend your time on your pages first.
Will blocking GPTBot remove my site from ChatGPT?
No. GPTBot collects content for training OpenAI's models, while ChatGPT search uses a separate crawler, OAI-SearchBot. You can disallow GPTBot and still appear in ChatGPT search. Blocking Google-Extended stops Gemini training on your content and its use for grounding answers in the Gemini app, but according to Google it does not affect inclusion or ranking in Google Search.
Does FAQ schema still help SEO in 2026?
Not for rich results. Google stopped showing FAQ rich results on 7 May 2026, after limiting them to government and health websites in 2023. FAQ sections are still worth writing, because AI assistants quote short, direct answers to real questions. Existing FAQ markup does no harm and other search engines may still read it.
How can I tell if AI search engines cite my website?
Use Bing Webmaster Tools' AI Performance report, which shows how often Copilot cites each page, look for referrals from chatgpt.com, perplexity.ai and copilot.microsoft.com in Google Analytics, and ask the main assistants your customers' top questions each month. Google Search Console counts AI Overviews and AI Mode inside its Web search figures.
How long does SEO and GEO take for a small business?
Fixing crawler access and indexing can show results within days, and OpenAI says robots.txt changes reach ChatGPT search in about 24 hours. New pages usually take weeks to be indexed and ranked, and the reviews, media mentions and links that make AI assistants confident in recommending you build up over months, so plan for at least three to six months.
The bottom line
GEO is not a new discipline for a small business to master. It is SEO done properly, with four additions.
- Let the AI search crawlers in. Check robots.txt and your host's bot blocker before anything else.
- Write passages that answer a question in their first sentence, name the place, and carry a number, a date and a source.
- Get described by others: reviews, local media, directories and partners, with your name and details identical everywhere.
- Measure it with Bing Webmaster Tools, Google Analytics and a monthly look at what the assistants say about you.
