ChatGPT SEO: How to Get Your Website Cited by ChatGPT
ChatGPT SEO is the practice of optimizing your website so that ChatGPT cites your content, brand or products when users ask questions in your industry. It is a subset of GEO (Generative Engine Optimization) focused specifically on OpenAI's models — which process over 4.2 billion queries per month.
For a Singapore SME, the goal is refreshingly concrete. When a customer asks ChatGPT to recommend a product or service "in Singapore", the AI cites 2-5 sources. Your name should be one of them.
How ChatGPT Selects Sources (What We Know)
OpenAI has not published its full citation algorithm, but analysis of thousands of ChatGPT responses — including industry queries from Singapore and the wider region — reveals consistent patterns. ChatGPT prefers to cite sources that are:
- Entity-verified — Sites with Organization schema and sameAs links to profiles AI trusts (LinkedIn, Google Business Profile, Crunchbase). A consistent registered business name and address across the web reinforce this.
- Rich in structured data — JSON-LD markup (Organization, Article, FAQPage) helps ChatGPT understand what your content is and whether it is relevant to the query.
- Comprehensive — ChatGPT almost never cites pages under 500 words. It favours pages that cover a topic deeply enough to excerpt from multiple sections.
- Recent — Pages with datePublished signals within the last 6 months are cited far more often than older content, even when the older content is higher quality.
- Well-cited elsewhere — ChatGPT learns which sources are frequently linked to across the web. Content that other authoritative sites — local media, directories, industry bodies — link to gets a compounding advantage.
7-Step Framework to Get Cited by ChatGPT
Step 1: Add Organization Schema with sameAs Links
This is the single most important technical change. Organization schema tells ChatGPT who you are. sameAs links prove it by connecting to the profiles it already knows. Use your registered company name and a consistent address — an unverifiable entity rarely gets cited.
Step 2: Implement FAQPage Schema on Every Relevant Page
FAQPage schema tells ChatGPT "this page answers specific questions." ChatGPT extracts Q&A pairs from pages with this markup far more often than from unstructured content. Each question should be a real query your customers ask — "Do you provide islandwide delivery?", "What are your opening hours?" — and each answer should be 2-4 sentences, clear and directly responsive.
Step 3: Write Content That Answers Specific Questions
ChatGPT cites content that directly answers the user's question. Vague marketing pages do not get cited. Pages structured as "What is X?" or "How to do Y in Singapore?" with clear, direct answers do. Before publishing anything, ask: what specific question does this page answer that someone would type into ChatGPT?
Step 4: Expand Content Depth to 1,000+ Words
AISight audit data shows a clear threshold: content under 500 words is almost never cited by ChatGPT. Content at 800-1,200 words has moderate citation rates. Content above 1,500 words with clear section headers and lists has the highest rates. Depth matters because ChatGPT needs multiple excerptable passages to draw from — and most SME competitors are still publishing 300-word pages.
Step 5: Add datePublished and dateModified
ChatGPT heavily weights recency. A page from 2024 describing 2026 prices or rules will lose to an updated page every time. Add datePublished and dateModified to your Article schema or as meta tags — and update them whenever you change pricing, menus, processes or regulations. Frequent updates are also a strong signal that your business is active.
Step 6: Build External Citation Signals
ChatGPT learns which sources are trusted by observing citation patterns across the web. Link to the authoritative sources your customers trust — government portals such as Gov.sg, ACRA and IMDA, industry associations and reputable local media — and get your business listed in reputable local directories. Every external citation of your content increases the chance ChatGPT cites you.
Step 7: Monitor and Iterate
Regularly ask ChatGPT the questions your customers ask and note whether your brand appears. Track which pages get cited and which do not. Monitor the same queries in Perplexity and Google AI Overviews — different models cite different sources. And run a monthly AISight audit to catch regressions in your schema or content freshness before they cost you citations.
Common ChatGPT SEO Mistakes
- Focusing only on backlinks — Backlinks help Google rankings. They have minimal impact on ChatGPT citations. If you spend all your effort on link building, you are optimizing for the wrong engine.
- Neglecting schema — Most SME sites have zero JSON-LD. Of those that do, most have incomplete or broken schema. Validated, complete schema is the single highest-ROI ChatGPT SEO investment available to a small business.
- Publishing thin content — ChatGPT rewards depth. A 300-word blog post will never compete with a 1,500-word guide, no matter how well-written the short post is.
- Not updating old content — ChatGPT deprioritizes stale content. If your best pages are from 2024, update them with current information and new dateModified signals.
- Assuming SEO = ChatGPT visibility — The overlap is only partial. A modest SME site with clean schema and entity signals routinely out-cites a big-brand site with zero structured data — we see it in almost every AISight industry survey.
How to Know If It's Working
Unlike Google, ChatGPT does not provide a "Search Console" for citation data. You need to measure manually or use a monitoring tool:
- Manual testing — Monthly: ask ChatGPT 5-10 industry questions and record whether your brand is cited.
- Referral analytics — Check your analytics for referral traffic from chat.openai.com (ChatGPT now includes source links).
- AISight Score — AISight fetches and analyses your site across the 7 dimensions ChatGPT and other AI models use for citation decisions, then tracks your AISight Score over time. Run it monthly and watch the number climb as you close each gap.
