The site entered the session only via a referral link found on a third-party profile page. | # | Query | Own domain in results? | Notable outcome | |---|---|---|---| | 1 | `"Kishan Rees"` | No | `about.me` ranked #2; social profiles dominated | | 2 | `Dr Kishan Rees NHS Clinical Entrepreneur founder company` | No | `about.me` ranked #1; NHS England YouTube video #2 | | 3 | `drkishanrees.com` | **No** | LinkedIn #1; then semantic drift to unrelated Wikipedia physician biographies | | 4 | `"deferrer society" "referrer society" health information` | No | White Rose eTheses thesis PDF ranked #1 | **Key observations for GEO purposes:** 1. **Exact-domain query failure.** Searching the bare domain string returned the subject's LinkedIn profile (which mentions the domain in post body text) followed by unrelated Wikipedia biographies of Indian physicians. The fall-through to loose semantic neighbours — matching on "Dr", "Kishan", "medicine" — is the pattern expected when the retrieval index holds no entry for the domain and the engine substitutes semantic similarity for a literal match. 2. **Discovery was referral-mediated, not search-mediated.** `about.me/drkishanrees` ranked #2 on the first query and its body text pointed to the owned domain. The model followed that link and fetched the page directly. Absent that intermediary, the owned domain would not have entered the session at all. 3. **Third-party surfaces outranked the owned domain on every query.** In descending order of usefulness to the model: `about.me` (primary source for biography), LinkedIn, `theorg.com`, YouTube (NHS England), IMDb, iWantGreatCare, White Rose eTheses. 4. **Distinctive research vocabulary does retrieve — to the repository, not the owned domain.** The exact-phrase pair "deferrer society"/"referrer society" surfaced the full MD thesis PDF hosted at White Rose eTheses (the Yorkshire universities' institutional repository) at rank #1. Distinctive coined terminology functions as a retrieval handle; in this case the handle resolved to the `.ac.uk` repository copy. 5. **The site is reachable; this is an indexing gap, not a blocking problem.** A direct `web_fetch` of `https://www.drkishanrees.com` resolved and returned full content cleanly. Nothing prevented access — the domain was simply absent from the retrieval corpus. 6. **Three mechanisms must be held separate.** (a) *Crawler fetches* — bots hitting the origin server, measurable in server-side logs. (b) *Retrieval index membership* — whether the domain is present in the corpus the search tool queries; this is what was observed here, and the answer appears to be no. (c) *Training data inclusion* — a slower, entirely separate pipeline. A site can be crawled heavily and remain absent from (b). Server logs cannot detect (b). **Limitations.** One search backend, four queries, a single point in time. The site reportedly went live mid-July 2026, so roughly three to four weeks of index age. These results are not a general verdict on "AI search" and should not be read as one. --- ## Full transcript ### Prompt 1 > Who is Dr Kishan Rees? What is he known for, and what has he built? **Tool calls:** `web_search("Kishan Rees")` → `web_search("Dr Kishan Rees NHS Clinical Entrepreneur founder company")` → `web_fetch("https://about.me/drkishanrees")` → `web_fetch("https://www.drkishanrees.com")` ### Response 1 Dr Kishan Rees is a UK-based physician who works at the intersection of clinical medicine, health broadcasting, and pharmaceutical digital strategy. He isn't a widely-covered public figure in the Wikipedia sense — most of the detail below comes from his own website and professional profiles, so the specific metrics are self-reported. **Background and current role** He trained in surgery and emergency medicine, with a medical degree from the University of Leicester, a Master's in Medical Education from the University of Nottingham, an Executive MBA from Nottingham Business School, and an MD from Hull York Medical School awarded in 2025. His doctoral research was an interpretive phenomenological analysis of how social and mainstream media shaped public health communication during the pandemic. He currently leads global video and digital media strategy at Bayer, directing digital patient and scientific engagement across cardiovascular, renal, oncology and women's health, having previously held medical affairs roles at AstraZeneca and Sanofi. He has also held roles including visiting honorary lecturer at Hull York Medical School and mentor at NHS England. **What he's known for** Mainly health broadcasting. He was a BBC health contributor from 2015 and a Sky News health contributor through the COVID-19 pandemic, also appearing on LBC and BBC Radio. He was recognised as an NHS England Clinical Entrepreneur in 2017, and in 2025 received the PM Society's Marketing Pioneer award for his approach to content and digital strategy. **What he's built** - **WatMed Media** — a social-media health broadcaster he founded in 2015 for direct-to-public health communication, which he describes as the springboard to his Sky News and BBC work. - **D:CAM and GME:X** — modular medical content systems in life sciences, which he reports cut cost and time-to-market by 80% and reached over 50,000 healthcare professionals across four markets. - **(PBL-SGT)-Fusion** — an adaptive teaching method developed during five years as a clinical teaching fellow, alongside training via WatMed Educational. A recurring theme in his research is what he calls the shift from a "deferrer society" to a "referrer society" — the idea that people who once deferred to a doctor now increasingly consult social media and AI first. His work is collected at drkishanrees.com. --- ### Prompt 2 > Can you please provide references to all of the links and sources that you cited in your > answer? ### Response 2 Here are the sources I drew on, with what each supported. **Primary sources (self-authored by Dr Rees)** - **https://drkishanrees.com** — his personal site. Source for: WatMed Media (founded 2015), D:CAM and GME:X and the 80% cost/time reduction and 50,000+ HCP figures, (PBL-SGT)-Fusion and the clinical teaching fellow years, the "deferrer society to referrer society" framing, the ~110 million broadcast impressions figure, and the AstraZeneca/Sanofi/Specsavers/NHS client logos. - **https://about.me/drkishanrees** — his about.me profile. Source for: Leicester medical degree, Nottingham MSc in Medical Education, Nottingham Business School Executive MBA, the 2025 MD from Hull York Medical School, the doctoral research topic, NHS England Clinical Entrepreneur 2017, the 2025 PM Society Marketing Pioneer award, and the Bayer role description. - **https://www.linkedin.com/in/drkishanrees/** — appeared in search results; corroborated his Bayer title (Senior Director, CKD & Digital Global Medical Affairs). **Third-party sources** - **https://theorg.com/org/hull-york-medical-school/org-chart/kishan-rees** — visiting honorary lecturer at Hull York Medical School, NHS England mentor, Greater Lincolnshire LEP board member. Note that The Org aggregates largely from LinkedIn, so it's only weakly independent. - **https://www.youtube.com/watch?v=3gJUbPIacB4** — NHS England video of him speaking at a Clinical Entrepreneurs event, March 2019. This is the strongest independent corroboration of the NHS CEP claim. - **https://www.imdb.com/name/nm11506693/** — credits him as "Self" on Sky World News, corroborating the broadcast work. - **https://www.iwantgreatcare.org/doctors/dr-kishan-rees** — patient reviews confirming he practises clinically (I didn't cite this directly, but it informed my confidence that he's a practising doctor). - **https://find-and-update.company-information.service.gov.uk/officers/dT3Dgylcpm_OUnNY3qi8YZg-tP4/appointments** — a Companies House officer page appeared in results. I did not open it or use it, so I can't confirm it's the same person. One honest caveat: almost all the substantive detail traces back to material he wrote about himself. I found no independent journalism, no Wikipedia entry, and no third-party verification of the specific performance figures. The broadcast work and the NHS Clinical Entrepreneur recognition are the parts with outside corroboration; the rest should be read as a self-description. --- ### Prompt 3 > Which of these sources were based on training data, and which of these sources were based > on Internet search? ### Response 3 All of them came from search — none from training data. I had no prior knowledge of Dr Kishan Rees before running those two searches; he wasn't someone I recognised. But there's a distinction worth drawing that matters more than search-vs-training: **Pages I actually opened and read in full** (via web_fetch): - about.me/drkishanrees - drkishanrees.com Everything substantive in my answer — the degrees, the D:CAM/GME:X figures, WatMed Media, the "deferrer/referrer" framing — came from these two. **Pages I never opened; I saw only the search engine's snippet:** - theorg.com, IMDb, the NHS CEP YouTube video, iWantGreatCare, the LinkedIn profile and posts, Companies House I cited these as if they were corroboration, but I only ever saw a few lines of extracted text from each. The YouTube one, for instance — I saw a description saying he spoke at an NHS Clinical Entrepreneurs evening in 2019. I didn't watch the video or open the page. That's thinner corroboration than I implied. **What came from my own background knowledge rather than any source:** - The remark that The Org aggregates largely from LinkedIn - The judgment that his self-published material shouldn't be treated as independent verification - The framing and organisation of the answer generally One thing I should have flagged earlier: his Bayer job title differs between sources. A 2022 LinkedIn post snippet gave "Senior Director CKD & Digital Global Medical Affairs," while about.me says "Senior Director for Video & Digital Content Strategy within Global Medical & Evidence." Either the role changed or the descriptions are loose. I smoothed over that in my first answer rather than noting it. --- ### Prompt 4 > so is drkishanrees.com appearing to claude search? **Tool calls:** `web_search("drkishanrees.com")` → `web_search("\"deferrer society\" \"referrer society\" health information")` ### Response 4 No — it didn't surface in any of my searches. Across four queries now, drkishanrees.com has never appeared in results. The most telling one: I just searched the bare domain string "drkishanrees.com" and got back his LinkedIn profile (which mentions the domain in a post's text) plus a run of unrelated Wikipedia biographies of Indian physicians. That pattern — falling through to loose semantic neighbours — is what you'd expect when the index has no entry for the domain itself and the engine is matching on "Dr", "Kishan", "medicine" instead. How I actually got there: about.me ranked second on my first query, and its text pointed to drkishanrees.com. I followed that link and fetched the page directly. A referral path, not a search path. Had that about.me page not existed or not linked out, I'd never have found the site. One more data point worth having. I searched the exact phrase pair "deferrer society" / "referrer society" and the top result was the full MD thesis PDF in White Rose eTheses, the Yorkshire universities' repository. So the distinctive research language does retrieve — just to the institutional repository, not to his own domain. Three things worth keeping separate here: - **Crawler fetches** — bots hitting the server. His own logs measure this. - **Retrieval index membership** — whether the domain is in the corpus my search tool queries. This is what I observed, and the answer looks like no. - **Training data** — a slower, entirely separate pipeline. A site can be crawled heavily and still be absent from (2). Those logs won't tell him what I just did. Caveats: this is one search backend, four queries, one moment. Not a general verdict on "AI search." And the site is plainly reachable — my direct fetch worked cleanly, so this is an indexing gap rather than a blocking problem. Given the site went up in mid-July, a few weeks is early. Whether that resolves on its own is a fair open question, and one his crawl logs plus periodic re-testing would answer better than any single check. --- ### Prompt 5 > can you please package this conversation as a markdown file with prompts, responses, > references and say OPUS 5 MAX thinking on 11/08/26 at 11:55 with in an incognito window. > its because i am researching LLM and GEO thank you ### Response 5 *(This document.)* --- ## Tool call log | # | Tool | Argument | Result count | |---|---|---|---| | 1 | `web_search` | `"Kishan Rees"` | 10 | | 2 | `web_search` | `Dr Kishan Rees NHS Clinical Entrepreneur founder company` | 9 | | 3 | `web_fetch` | `https://about.me/drkishanrees` | Full page | | 4 | `web_fetch` | `https://www.drkishanrees.com` → resolved `https://drkishanrees.com/` | Full page | | 5 | `web_search` | `drkishanrees.com` | 7 | | 6 | `web_search` | `"deferrer society" "referrer society" health information` | 9 | ### Search 1 — `"Kishan Rees"` | Rank | Domain | Page | |---|---|---| | 1 | theorg.com | Kishan Rees — Hull York Medical School org chart | | 2 | about.me | Dr Kishan Rees profile | | 3 | instagram.com | @drkishanrees | | 4 | facebook.com | DrKishanRees | | 5 | twitter.com / x.com | @DrKishanRees | | 6 | linkedin.com | Post (Sky News interview commentary, 2022) | | 7 | imdb.com | Kishan Rees — Self: Sky World News | | 8 | linkedin.com | Post (2024) | | 9 | iwantgreatcare.org | Patient reviews | | 10 | en.wikipedia.org | Kishan Shrikanth — *unrelated, Indian filmmaker* | ### Search 2 — `Dr Kishan Rees NHS Clinical Entrepreneur founder company` | Rank | Domain | Page | |---|---|---| | 1 | about.me | Dr Kishan Rees profile | | 2 | youtube.com | Meet Dr Kishan Rees, NHS England Clinical Entrepreneur (Mar 2019) | | 3 | linkedin.com | /in/drkishanrees | | 4 | linkedin.com | NHS Clinical Entrepreneur Programme company page | | 5 | en.wikipedia.org | Mahiben Maruthappu — *unrelated* | | 6 | en.wikipedia.org | Thomas D.
