Why your practice's website probably won't be cited by ChatGPT (and how to fix it)

Most Australian allied health practice websites are completely invisible to AI search engines. Three structural patterns are missing — direct-answer leads, schema markup, and an llms.txt file — and fixing all three takes about a day of focused work. Get them right and you’ll start showing up in ChatGPT, Perplexity, and Google AI Overviews answers within 60 to 120 days.

How AI search engines decide who to cite

AI search engines cite sources that they can parse confidently and that directly answer the user’s question. Two mechanisms are at work: training data (what the model was trained on, months ago) and retrieval-augmented generation (what the model fetches in real time when you ask).

Both pathways favour the same kind of content: pages that lead with a clear, factual answer; pages with structured data that machines can read without ambiguity; pages that signal — through schema, sitemaps, and standards like llms.txt — what they’re actually about. Vague brochure copy (“we believe in holistic wellbeing journeys”) doesn’t get cited. A sentence like “A Medicare-rebated psychology session in Melbourne costs between $180 and $260, with a $97.20 rebate from a Mental Health Care Plan” does.

The three patterns missing from most practice sites

These three patterns are present on almost every page that gets cited, and absent from almost every typical Australian practice site.

1. Direct-answer leads

Most practice websites bury the answer. The page about “Anxiety treatment” opens with three paragraphs of preamble: who the practice is, why mental health matters, what their approach is. The actual answer to “what is anxiety treatment” appears on paragraph four, if at all.

AI search engines stop reading well before paragraph four. They want the first 1–2 sentences after the heading to answer the implied question. Restructure your service pages so the very first thing under each heading is a direct, factual answer.

2. Schema markup

Schema is structured data — invisible to humans, parseable by machines — that tells search engines exactly what your page contains. For allied health, the four schema types that matter most are LocalBusiness, MedicalBusiness, FAQPage, and Article. Most practice sites have none of them. Adding them is a one-time job.

3. llms.txt

An emerging standard (modelled on robots.txt and sitemap.xml) that tells AI crawlers what your site is about, which pages matter, and how to navigate them. A simple text file at the root of your domain. Almost no Australian practice has one. Adding it makes your site easier to ingest, which makes citation more likely.

An example of a well-structured vs poorly-structured page

The difference is stark in side-by-side comparison.

Poorly structured (typical practice site):

Welcome to our practice. We are passionate about mental wellbeing and our holistic, person-centred approach is designed to support you on your journey towards better mental health. Our experienced team brings decades of combined experience in providing compassionate, evidence-based care…

Well-structured (citation-ready):

A psychology session at our Melbourne practice costs $220 for a standard 50-minute appointment. With a Mental Health Care Plan from your GP, Medicare rebates $97.20 per session, leaving an out-of-pocket cost of $122.80. We bulk-bill concession card holders for the first six sessions of the calendar year.

Who we treat

We see adults aged 18+ for anxiety, depression, trauma, and ADHD assessment. We do not treat children under 18 or provide forensic reports.

The second version answers questions. The first version describes feelings. AI search engines cite the first version exactly zero percent of the time and cite the second version meaningfully more.

How to test whether ChatGPT/Perplexity cite you

You can’t measure GEO the way you measure SEO, but you can spot-check.

• Search ChatGPT directly. Try: “What does a psychology session cost in [your suburb]?” If a competitor is named in the answer, click the citation chip — that’s the kind of structure you need.
• Try Perplexity. It surfaces sources more transparently than ChatGPT. The citation chips next to each sentence show exactly which pages are getting credit. Are you in there for queries you should win?
• Test Google AI Overviews. Search a query you’d want to rank for (“psychologist near me [suburb]”). Is there an AI Overview? Whose pages are linked in the citation badges?
• Run the same query 3 times. AI answers are non-deterministic. One run isn’t a signal — three consistent runs is.

A good signal: you appear in 2 of 3 runs for a high-intent local query. A bad signal: you don’t appear at all and a competitor consistently does.

A 30-day plan to start getting cited

If you’re starting from zero, here’s how to spend the next month.

Week	Focus	Specific tasks
Week 1	Restructure your top 3 pages	Rewrite homepage, services page, and most-trafficked service-detail page so each section leads with a 1–2 sentence direct answer.
Week 2	Add schema	Add LocalBusiness (or MedicalBusiness) schema to homepage and contact page. Add FAQPage schema to any page with Q&A content. Validate with Google’s Rich Results Test.
Week 3	Crawler permissions and llms.txt	Check robots.txt doesn’t block GPTBot, ClaudeBot, PerplexityBot, Google-Extended. Write and publish a /llms.txt file describing your site’s purpose, services, and key pages.
Week 4	Measurement and iteration	Run baseline queries in ChatGPT, Perplexity, and Google AI Overviews. Document which pages get cited (and which don’t). Iterate on the pages that are still invisible.

Citations build slowly — you usually won’t see results for 60–120 days after the changes go live. But the pages that are structured this way today are the ones that will be cited a year from now.
