Websites are now the source type health and science students cite most after journal articles — NHS guidance pages, charity information sheets, government statistics — yet they are the entries most often returned by markers with comments. The Vancouver website reference has more moving parts than the book or article formats: an author or organisation, the page title, the site name, the marker “[Internet]”, publication or update dates, a “[cited]” date recording when you read the page, and the full URL after the words “Available from:”. Leave any one of them out and the reference is incomplete. This guide builds the format element by element, with worked examples for single pages, whole websites, pages with no named author and the government and NHS pages that dominate real health-science reference lists. To format a reference automatically from a page’s details, use the Vancouver Referencing Generator; the full system is set out in our Vancouver referencing guide, with companion pages on how to reference a book in Vancouver style and Vancouver in-text citations.
The basic format, element by element
A Vancouver reference for a webpage follows the pattern set by the National Library of Medicine’s Citing Medicine, the style authority the ICMJE points to for reference formats:
Author or Organisation. Page title [Internet]. Place of publication: Publisher; Year [updated Year Month Day; cited Year Month Day]. Available from: URL
Each element earns its place. The author is the person or organisation responsible for the page. The page title is in sentence case — capital letter on the first word and on proper nouns only — with no italics, as everywhere in Vancouver. [Internet] in square brackets immediately after the title flags the medium, and it is not optional in the NLM format. The place and publisher are those of the organisation behind the site, where they are known. The date is the year the page was published, with an update date added where the page shows one. The [cited] date is the day you consulted the page, in the order year, month abbreviated, day. Finally, Available from: introduces the complete URL of the page you used. A finished reference looks like this:
Diabetes Care Foundation. Managing blood glucose at home [Internet]. London: Diabetes Care Foundation; 2023 [updated 2025 Mar 4; cited 2026 Oct 28]. Available from: https://www.diabetescarefoundation.org.uk/living-with-diabetes/blood-glucose
A single page is not the whole website
The most useful habit in website referencing is to cite the page you actually used, not the site it lives on. A reference to a specific guidance page names that page’s title and gives that page’s URL, so a reader lands on the exact text you relied on. The example above does this: the title is the page’s title, and the URL is the deep link to the page, not the foundation’s homepage.
A reference to a website as a whole is a different entry, used only when your point is about the site itself — its existence, its coverage, its publisher — rather than anything a particular page says. In that case the site name takes the title position:
Patient Voices Network [Internet]. Manchester: Patient Voices Network; c2024 [cited 2026 Oct 28]. Available from: https://www.patientvoicesnetwork.org.uk/
Note the “c” before the year, marking a copyright date used because no publication date is given — a standard NLM device for websites. What you should not do is blend the two forms: a specific claim in your text supported by a homepage reference sends your reader to a front door with no directions, and markers treat it as an unfinished reference.
Pages with no named author
Most webpages carry no personal byline, and Vancouver’s answer is straightforward: the organisation that publishes the page becomes the author. Charities, universities, companies and public bodies are corporate authors in exactly the way they are for reports and guidelines. The Diabetes Care Foundation example above works this way — no individual wrote the page under their own name, so the foundation stands in the author position, and because the organisation is also effectively the publisher, its name can appear in both places without apology.
If a page has neither a named person nor an identifiable organisation behind it — rare on any site worth citing — begin the reference with the page title instead, followed by [Internet] and the remaining elements. Treat the absence of any responsible author as a warning sign about the source itself, though: for academic work, a page nobody will put their name or organisation to is a page to replace with a better source rather than to rescue with formatting.
Government and NHS pages: the commonest real case
For nursing, midwifery, pharmacy and allied health students, the websites cited most are not commercial at all — they are pages from the NHS, the Department of Health and Social Care, NICE and other public bodies. These follow the same format, with the body as corporate author and its site as the place the page lives:
NHS. Conditions: coeliac disease [Internet]. London: NHS; 2023 [updated 2025 Jun 19; cited 2026 Oct 30]. Available from: https://www.nhs.uk/conditions/coeliac-disease/
Department of Health and Social Care. Adult social care workforce strategy [Internet]. London: GOV.UK; 2025 [cited 2026 Nov 1]. Available from: https://www.gov.uk/government/publications/adult-social-care-workforce-strategy
Two practical points arise with these pages constantly. First, NHS and GOV.UK pages display “last reviewed” or “last updated” dates prominently — use the update date in the [updated] slot, because that is the version of the guidance you read, and keep the original publication year where the page gives one. Second, cite the specific condition, guideline or publication page, never the nhs.uk or gov.uk homepage; these sites are enormous, and a homepage URL verifies nothing. Where a page is one part of a larger online document — a single section of a NICE guideline, for instance — name the section in the title position so the reference points at the part you used.
The in-text number: a brief reminder
Nothing about a website changes Vancouver’s in-text mechanics. The page takes the next number in the order of first citation in your text — in brackets, round brackets or superscript, whichever your department prescribes — and that number is the entry’s position in the reference list. If the NHS page above is the fourth source you cite, it is (4) in the text and entry 4 in the list, however early or late alphabetically “NHS” would fall. Cite the same page again later and you reuse the same number; you do not give a website a fresh number on each mention. Because inserting one new source renumbers everything after it, add web references as you write rather than reconstructing the order at the end. The full rules are in our guide to Vancouver in-text citations.
Why there is no DOI in a website reference
Students who have learned to hunt for DOIs on journal articles sometimes try to attach one to a webpage, or worry that its absence makes the reference incomplete. It does not. A DOI identifies a specific registered object — typically a journal article, book or chapter deposited with a registration agency. Ordinary webpages have no DOI; they are located by their URL, which is why the Vancouver website format ends with “Available from:” and the address instead. If the thing you found online does carry a DOI, that is a strong sign it is not really a “website” for referencing purposes at all: it is an article, report or e-book that happens to be delivered online, and it should be referenced under that source type’s format, DOI included, rather than forced into the website pattern.
Common errors with website references
The same five errors recur. Missing the cited date is the commonest: because webpages change silently, the [cited] date is part of the evidence for what you read, and NLM’s own examples carry one on every internet reference. Pasting the homepage URL for a deep page makes the reference unverifiable. Italicising the page title imports Harvard habit into a style that uses no italics in the reference list. Writing “Accessed:” with a day-month-year date mixes Harvard phrasing and date order into a Vancouver entry that wants [cited Year Mon Day]. And alphabetising the list breaks the numbered logic entirely — websites sit in citation order with everything else. Each error is small; together they tell a marker the list was assembled from habit rather than from the style.

Frequently asked questions
Do I reference the webpage or the whole website? The webpage, whenever you are relying on something it says — its title and its own URL. Reference the whole site only when your point is about the site itself.
What date goes in [cited]? The date you consulted the page, in the format [cited 2026 Oct 28] — year, abbreviated month, day. If you revisit the page and the content has changed, update the citation and the cited date together.
Who is the author of an NHS page? The NHS, as a corporate author. Public bodies and organisations stand in the author position when no individual is named, which is the normal situation for government and health-service pages.
Should I include a DOI for a website? No. Webpages are located by URL after “Available from:”. If your online source has a DOI, it is almost certainly an article, book or report and should be referenced in that format instead.
Does the URL need the full address of the page? Yes — the complete URL of the specific page you used, copied exactly. A homepage address or a shortened link does not let your reader verify the reference.
What if the page shows no date at all? Use the site’s copyright year with a “c” before it, as in c2024, and keep the [cited] date, which matters even more when the page itself is undated. Do not invent a publication date.
