In October 2026, a free Aemorph [Hallucination Report](https://tools.aemorph.com/hallucination) found 25 AI answers that contradicted the website of Better People, an Australian AI training company, across 38 facts. Aemorph's diagnostic traces each leak to the buyer question behind it, so you fix the answer instead of buying more Google or Bing ads to replace the buyers you lost.

[LinkedIn](https://www.linkedin.com/in/kevindam) --- ## Lead Leakage Shows as Steady Visibility and Fewer Buyers Reaching You **For Australian businesses, lead leakage shows up as steady Google and Bing rankings and steady ad spend alongside fewer or weaker enquiries, because buyers settle their shortlist inside AI answers you never see.** Your reports look healthy while buyers ready to enquire choose someone else before they click. | Symptom | What the buyer sees | Likely cause to test | Fix | Where it gets fixed | | --- | --- | --- | --- | --- | | Rankings hold, enquiries soften | A competitor named first when the buyer asks an AI chat for options | The sources an AI answer draws on state a competitor's strengths more clearly than yours | Publish clear answers to the comparison questions buyers ask | Your site and the sources the answer draws on | | Enquiries arrive with wrong expectations | A wrong price, service or location stated about you | An outdated or AI-generated source about your business | Correct the source and publish the approved fact | The page or profile carrying the old fact | | You are missing from "best provider" answers | A list of Australian providers in your category without you | AI places your business in the wrong category | Restate your category the same way on each channel | Your site, profiles and directories | | Buyers ask for services you do not sell | A service attributed to you that you do not offer | A guessed or generalised description of your business | Publish the approved service list | Service pages and your LLM info page | *Symptoms, likely causes and fixes for lead leakage in AI answers about an Australian business.* Miscategorisation is covered in brand categorisation in AI, and answers that differ from one AI chat to the next in [cross-platform AI brand inconsistency](https://aemorph.com/en-au/guides/cross-platform-ai-brand-inconsistency/). ### What is lead leakage in AI search? **Lead leakage in AI search is the loss of Australian buyers who research your category in an AI chat or AI answer and leave with a competitor's name, a wrong fact about you or no mention of you at all.** These buyers rarely show up in your analytics, because the decision happens before any click. A wrong fact about you is an AI hallucination, and the [AI hallucination fix for brands](https://aemorph.com/en-au/guides/ai-hallucination-fix-for-brands/) corrects what the AI chats get wrong about your business. --- ## Buyers Leak Before Your Site Because the AI Answer Does the Shortlisting **Australian buyers leak before they reach your site because the AI answer now does the shortlisting a results page used to leave to them, and a buyer who gets a complete answer has less reason to click.** The engine answers from what it has learned and looked up about the providers in your category, and the buyer reads the answer instead of ten links. The click data shows the shift. In Pew Research's March 2025 study of 900 US adults, users clicked a traditional result in 8% of visits when an AI summary appeared, against 15% without one, and clicked a source cited inside the summary in 1% of visits. *[Source: Pew Research Center, July 2025](https://aemorph.com/sources/#pew-research-center-july-2025-ai-summary-clicks)* Business buyers want less contact too. Gartner's June 2025 survey of 632 B2B buyers found 61% prefer an overall rep-free buying experience, and Gartner's 2020 research put the time buyers spend meeting potential suppliers at 17% of a purchase decision. More of the decision happens in an answer you do not control, and less of it on your site or in a sales call where you correct a wrong impression. *[Sources: Gartner, June 2025 and September 2020](https://aemorph.com/sources/#gartner-june-2025-and-september-2020-lead-leakage-and-cac-diagnostic)* Aemorph's guide to [brand categorisation in AI](https://aemorph.com/en-au/guides/brand-categorisation-in-ai/) shows how an AI answer that files your business under the wrong category drops you from the shortlist before a buyer reaches your site. ### How does a wrong AI answer raise customer acquisition cost? **A wrong AI answer raises customer acquisition cost because it removes Australian buyers before they enter your funnel, so the same sales and marketing spend in dollars is divided across fewer new customers.** Customer acquisition cost, or CAC, is your total sales and marketing spend in a period divided by the new customers you won in that period. Aemorph does not see your spend or your customer count, so that arithmetic stays with your team. --- ## Australian Buyers Build Their Shortlist Across Google, Bing and the AI Chats **Australian buyers reach a shortlist through Google, Bing and the AI chats, so a leak opens on any of the three before a buyer contacts you.** [Google held 87.9% of search engine market share in Australia in September 2026 and Bing 9.17%](https://gs.statcounter.com/search-engine-market-share/all/australia) (StatCounter). | Measure | Figure | Market and date | Source | | --- | --- | --- | --- | | Google search engine market share | 87.9% | Australia, September 2026 | StatCounter | | Bing search engine market share | 9.17% | Australia, September 2026 | StatCounter | | Google AI Overviews | Rolled out Australia-wide | Australia, 29 October 2024 | [Google Australia](https://blog.google/intl/en-au/company-news/outreach-initiatives/ai-overviews-australia/) | | Google AI Mode | Rollout began, in English | Australia, 8 October 2025 | Google Australia | | Internet users | 26.2 million, 97.1% of the population | Australia, as of October 2025 | DataReportal | | Adults who recently used a generative AI tool | 45.6% | Australia, survey of more than 5,500 adults, published November 2025 | ADM+S | *[Sources: StatCounter, September 2026 and others](https://aemorph.com/sources/#statcounter-september-2026-and-others-ecd4)* Close to half of Australian adults had recently used a generative AI tool when ADM+S surveyed them, so a wrong AI answer about your business reaches a large share of the buyers researching your category. Aemorph tests each question cluster in the AI chats and checks Bing alongside Google for Australian clients. --- ## The Leak Diagnostic Traces Each Lost Buyer to the Question Behind It **The leak diagnostic identifies the buyer questions where AI answers omit or misrepresent your business: it lists the questions Australian buyers ask before they choose, tests what each AI chat answers and marks each answer that names a competitor, states a wrong fact or leaves you out.** Aemorph runs it in five steps: 1. **Lists** the questions a buyer credibly asks before choosing a provider in your category, using Aemorph's [EAV Exhaustion Methodology](https://aemorph.com/en-au/guides/eav-exhaustion-methodology/), from price and fit to risk and timing. 2. **Groups** the questions into clusters, one cluster per buying decision, so the result reads as a share of answers through cluster-level measurement, not as one keyword. 3. **Tests** each question in ChatGPT, Claude, Gemini and Perplexity, and records whether each answer names you, names a competitor first, states a wrong fact or leaves you out. 4. **Compares** each answer with what your own website says in answer to the same question, so a leak caused by your own site is told apart from one caused elsewhere. 5. **Ranks** the leaks by funnel stage, bottom-of-funnel questions first, because those buyers are closest to a decision. The test step matters because AI answers are often wrong in ways a buyer has no means to spot. In the European Broadcasting Union and BBC review of AI assistants, 45% of 2,709 evaluated answers to news questions had at least one significant issue. For Google's AI answers, a page appears as a supporting link only when it is indexed and eligible to show in Search with a snippet, according to Google's guidance on AI features. *[Sources: EBU and BBC, October 2025; Google Search Central, December 2025](https://aemorph.com/sources/#ebu-bbc-october-2025-and-google-december-2025-lead-leakage-and-cac-diagnostic)* ### Which buyer questions leak the most leads? **The questions that leak the most Australian leads are the price, comparison and fit questions asked just before a buyer chooses, because a wrong answer there removes a buyer who was ready to enquire.** Aemorph calls these [showstopper questions](https://aemorph.com/en-au/glossary/#showstopper-questions): the buyer questions that stop a purchase when AI answers them badly. ### What does the diagnostic measure, and what stays with your finance team? **The diagnostic measures how often AI answers name you, name a competitor first or state a wrong fact across each question cluster, while your revenue, enquiry counts and customer acquisition cost stay with your Australian team.** Aemorph tracks rankings, traffic and AI visibility, because those are what its work controls; it does not collect your sales, revenue or enquiry figures. Your team sets its own numbers against the visibility results to see whether the cost of each new customer falls. --- Aemorph's guide to [cluster-level measurement for AEO and GEO](https://aemorph.com/en-au/guides/cluster-level-measurement-for-aeo-geo/) explains why the diagnostic reports a share of answers per question cluster rather than one keyword position. ## Leaks Left in Place Widen as More Buyers Research in AI **A leak left in place costs you more Australian buyers as more of your market researches in AI before contacting anyone, because each buyer who asks the same question meets the same wrong answer.** Gartner forecast in February 2024 a 25% drop in traditional search engine volume by 2026 as AI chatbots and other virtual agents take a share of it. *[Source: Gartner, February 2024](https://aemorph.com/sources/#gartner-february-2024-lead-leakage-and-cac-diagnostic)* | Situation | Buyer impact | Aemorph's recommended recheck | Next step | What to retest | | --- | --- | --- | --- | --- | | One cluster leaking, such as price questions | Buyers comparing prices meet a competitor or a wrong fee | After the corrected answers go live | Publish the approved price basis | That cluster in the four AI chats | | Several clusters leaking | Buyers lose you at several stages of the decision | After the full diagnostic, bottom-of-funnel questions first | Run the diagnostic across the clusters | Each cluster in the AI chats and Google's AI answers | | Leaks plugged and monitored | The target: AI answers name you with the current facts | After a business change | Update the approved answers first, then the pages | Each cluster, after each change | *Buyer impact and recommended recheck by number of leaking clusters, as illustrative scenarios.* Aemorph sets no fixed recheck interval. Your first working day with Aemorph is the first check date, and pages are then assigned for update in order of importance: bottom-of-funnel, middle-of-funnel, then top-of-funnel. ### How often do you rerun the leak diagnostic? **You rerun the leak diagnostic after each correction you publish and whenever your offer, prices in Australian dollars or service areas change.** Aemorph reports monthly, with results grouped by topic and [prompt cluster](https://aemorph.com/en-au/glossary/#prompt-cluster). --- Aemorph's [Hallucination Diagnostic](https://aemorph.com/en-au/services/hallucination-diagnostic/) is the rerun's starting point: it tests a sample of 10 to 20 showstopper questions across ChatGPT, Gemini, Claude and Perplexity and compares each answer with your website. ## Corrections Stay Accurate, Provable and Signed Off by You **When you correct an AI answer about your business, each statement you publish has to be true and provable under the Australian Consumer Law, including any comparison with a competitor.** A correction that overstates your case swaps one false impression for another. The ACCC states that a business has to be able to prove any claim it advertises, and that it makes no difference whether the business intends to mislead or not. A comparison with a competitor falls under the same test. Aemorph's [ACCC and Australian Consumer Law guide](https://aemorph.com/en-au/guides/accc-australian-consumer-law-marketing/) covers the rules for marketing copy, and whether a specific claim is lawful is a question for a qualified Australian legal adviser. *[Source: ACCC, July 2026](https://aemorph.com/sources/#accc-july-2026-1866)* Your data stays yours. You keep ownership of your .com.au and other domains, Search Console, analytics, ad accounts and CRM, and Aemorph works under an access practice aligned with ISO 27001. Your nominated point of contact signs off regulated claims before Aemorph publishes them. *General guidance, not legal advice.* ### Is it lawful to name a competitor when you correct an AI answer? **A comparison you publish with a competitor has to be accurate and provable, because the Australian Consumer Law prohibits conduct that is misleading or deceptive or likely to mislead or deceive.** Whether a specific comparison is lawful is a question for a qualified Australian adviser. The safer correction states your own approved facts clearly and lets the buyer compare. --- ## The Showstopper Sensor Plugs Leaks at the Question **Leaks close for an Australian business when you know which buyer questions the AI chats answer badly and publish the approved answers they need on your own site.** The [Hallucination Diagnostic](https://aemorph.com/en-au/glossary/#hallucination-diagnostic) tests a sample of 10 to 20 showstopper questions across ChatGPT, Gemini, Claude and Perplexity, depending on the size and complexity of your business, and compares the answers with what your own website says, with the report delivered in 5 business days and presented on a call in Australian business hours.
