Websites are among the most common sources students cite, yet they are also where referencing slips happen most often. Web pages can lack an obvious author or date, and different referencing styles handle them differently. This UK guide shows you how to reference a website correctly in Harvard, APA 7 and MLA, what to do when details are missing, and the mistakes that cost easy marks.
The Short Answer
Every web reference needs the same four pieces of information: who is responsible for the page, what it is called, who is publishing it, and when. Add the exact address of the page you actually used and, in Harvard, the date you accessed it. Where there is no named person, the organisation goes in the author position; where there is no date at all, use the abbreviation your style requires rather than guessing. Cite the specific page rather than the homepage, avoid shortened or tracking-laden links, and check every address still works before you submit.Why Referencing Websites Correctly Matters
Citing web sources properly does two things: it credits the original author and lets your reader verify the information. Because web content can change or disappear, examiners pay close attention to how carefully you record it, including the date you accessed the page. Getting this right signals that your research is thorough and trustworthy, and it protects you from accidental plagiarism.
How to Reference a Website in Harvard Style
In Harvard style, an in-text citation gives the author and year, for example (Smith, 2024). The full reference in your list follows this pattern: Author or organisation (Year) Title of the web page. Available at: URL (Accessed: day month year). If a company or body is responsible for the page rather than a named person, use the organisation as the author. Always include the access date, since web pages are frequently updated.
How to Reference a Website in APA 7
APA 7 uses author–date in-text citations such as (Jones, 2024). The reference-list entry is: Author, A. A. (Year, Month Day). Title of the page. Site Name. URL. APA 7 only requires a retrieval date when the content is designed to change over time, such as a live statistics dashboard; for a stable page, no access date is needed. If there is no individual author, begin with the site or organisation name.
How to Reference a Website in MLA
MLA uses the core-elements system. A typical Works Cited entry reads: Author. “Title of the Page.” Title of the Website, Publisher (if different from the site), Publication date, URL. Accessed Day Month Year. The in-text citation is simply the author’s surname, or the page title in quotation marks if there is no author. MLA recommends an access date whenever the page has no clear publication date.

What to Do When the Author or Date Is Missing
Many web pages lack an obvious author or date, but you can still reference them. If there is no personal author, use the organisation responsible for the site. If there is no organisation either, move the page title into the author position. When no date is shown, use “n.d.” (no date) in Harvard and APA, or rely on the access date in MLA. Never invent a date — markers would rather see “n.d.” than a guess.
Common Mistakes When Referencing Websites
The most frequent errors are leaving out the access date in Harvard, pasting a bare URL with no author or title, citing the homepage when you used a specific page, and mismatching the in-text citation with the reference list. Watch out too for referencing a website when a more authoritative version exists — if a report is available as a PDF from the organisation, cite that instead of a news summary. Consistency across every entry is what examiners reward.
Referencing Websites in Chicago, MHRA and Vancouver
Chicago author–date treats a web page much like any other source: author, year, page title, site name, then the address. In the notes–bibliography system the same elements appear in a footnote in natural name order with commas between them. Chicago asks for an access date only where the page carries no publication or revision date, or where your department requires one as standard.
MHRA, being footnote-based, puts the page title in single quotation marks, names the site, gives the date of publication where available, and closes with the address in angle brackets followed by an access date in square brackets. Because MHRA is used in humanities subjects where sources are often archival, it is worth checking whether your department wants online material listed separately from print.
Vancouver numbers references in the order they appear and marks the medium in square brackets after the title, followed by the place and publisher where those are identifiable, the publication or update date, the access date, and the address. Full conventions for both footnote styles are set out in our Chicago referencing guide and MHRA referencing guide.
Where to Find the Details a Web Reference Needs
Most of what looks missing on a web page is actually there, just not where you first looked. Authors appear in bylines, at the foot of articles, and on “about this page” or contact links. Where no person is named, the organisation running the site is the author, and its formal name is usually in the footer or on the About page rather than in the logo.
Dates hide in three places: a publication or “last updated” line near the heading or at the foot of the article, the copyright statement in the footer — which dates the site rather than the page, so use it only as a last resort — and the page’s own metadata. Where a page shows both a published and an updated date, use the one your style asks for and be consistent across your reference list.
For the site name, use the name of the publication or organisation as it presents itself, not the domain. For the page title, use the main heading rather than the browser tab text, which is often padded with the site name. And copy the address from the browser bar of the page you actually read, stripping any tracking or session parameters from the end.
Deep Pages, Blogs, Wikis and Social Media
Always reference the page that contains the material you used, not the homepage you arrived through. A reader given only a site address has to search the whole site, which defeats the purpose of a reference. Where a document is split across several pages, cite the page you quoted and note the section heading if there are no page numbers.
Blog posts are referenced like articles, with the post author as author, the post title as the title, and the blog name as the site. Wikis need care: the content is collectively authored and changes constantly, so the entry title goes in the author position and an access date becomes essential. Encyclopaedias of any kind are usually better treated as a way into the literature than as a citable authority.
Social media posts follow the same logic as any short web source: the account name and handle, the opening words of the post in place of a title where there is no title, the platform, the posting date and the address. Because posts are frequently deleted, keep your own dated record of what you saw. Video sources have their own conventions, covered in our guide to referencing a YouTube video.
Government, NHS and Organisational Publications
Official UK sources are among the most useful material students cite and among the most often referenced badly. The key decision is whether you are citing a web page or a publication that happens to be online. A guidance page is a web page, with the department or body as author. A report, statistical release or policy document is a publication, and needs its title, any series or reference number, the publishing body and the year, with the address added at the end.
Use the formal name of the body as it appears on the document, and keep it consistent throughout your reference list rather than alternating between a full name and an abbreviation. Where a document is issued by a named unit within a larger department, give both. Statistical releases usually carry an explicit publication date and a revision history, so cite the version you used.
Fixed-page documents such as reports and guidelines should be cited by their printed page numbers rather than by scroll position, which is covered in our guide to referencing a PDF. Where the same content exists as both a formal publication and a web summary, cite the publication — it is more durable and carries more weight.
Pages That Change or Disappear
Web sources are unstable, and a broken link in a reference list is an easy deduction for a marker. Prefer the most durable form available: a DOI over a database link, a publisher’s own page over an aggregator, a formal publication over a news summary of it. Where a page has a permalink or a versioned address, use that.
The access date exists precisely because content changes. It tells your reader that the page said what you claim on that day, which is why Harvard requires it for every online source and other styles require it whenever a page is undated or likely to be revised. Record it as you write rather than reconstructing it later.
Keep your own record too. A saved copy or dated screenshot of any page central to your argument protects you if the page is edited or removed before your work is marked. Where a page has already vanished, a reputable web archive can sometimes supply a dated snapshot, which you cite as the archived version alongside the original details. If neither exists, the honest course is to find another source rather than cite something no one can check.
When a Website Is the Wrong Source
Referencing a page correctly does not make it appropriate. Markers assess your choice of sources as well as your formatting, and a bibliography weighted towards web pages rarely reads well at university level. For established knowledge, prefer textbooks and peer-reviewed articles; for statistics and policy, prefer the originating body; for a theory, cite the original work rather than a page summarising it.
Encyclopaedias, revision sites and content farms are best treated as orientation. Use them to learn the vocabulary of a topic and to find the names of the researchers who matter, then read and cite those researchers. If a web page is the only support for a central claim, that claim is under-evidenced.
Generative AI tools are not sources at all. They do not hold the information they present, they can fabricate references that look convincing, and citing them as authorities misrepresents where your evidence came from. Use them at most to orient yourself, verify everything independently, and follow your university’s policy on declaring AI assistance — the checking habits in our guide to critical thinking skills apply directly.
A Quick Check Before You Submit
Go through your web references one at a time and confirm five things: an author or organisation in the author position, a real page title rather than a browser tab label, the site or publisher named, a date that belongs to the page rather than the site, and an access date where your style requires one.
Then click every link. Check that it opens the page you meant, that it works when you are not signed in to your university network, and that no tracking or search parameters are left on the end. Anything that only opens from inside a library proxy should be replaced with a DOI or a publisher address.
Finally, look at the balance of your list. If web pages outnumber your books, chapters and journal articles, the fix is more reading rather than better formatting. Our guide to referencing a book covers the print templates you will need most.
Frequently Asked Questions
Do I need an access date when referencing a website?
In Harvard style, yes — always include the date you accessed the page. In APA 7 you only need a retrieval date for content that changes over time, and in MLA an access date is recommended when no publication date is given.
How do I reference a website with no author?
Use the organisation responsible for the site as the author. If there is no organisation, move the page title into the author position. Do not use “Anonymous” unless the source itself is credited that way.
Should I include the full URL?
Yes. Include the full, working URL so your reader can find the exact page. For a specific article or page, link to that page rather than the site’s homepage.
Can I cite Wikipedia in a university essay?
It is generally not accepted as an authority, because entries are collectively authored and can change at any time. Use it to get oriented and to find the names of researchers and primary sources, then read and cite those instead. If a module explicitly permits it, reference the entry title in the author position and always include an access date.
Should I reference the homepage or the specific page I used?
Always the specific page. A reference exists so a reader can reach the exact material you relied on, and a homepage forces them to search the site. Where a document runs across several pages, cite the page you quoted and identify the section heading if there are no page numbers.
What if the page needs a login or only opens on campus?
Replace the address with a more durable one wherever possible: a DOI, the publisher’s own page, or the formal publication rather than a proxy link. Where access is genuinely restricted, give the full reference details so the source can be identified, and note the database or platform through which you reached it. Never paste a link that only works while you are signed in.
How do I reference a UK government or NHS page?
Use the department, agency or body as the author under its formal name, give the page title, the site name and the publication or last-updated date, then the address and an access date if your style requires one. If you are citing a report or statistical release rather than a guidance page, treat it as a publication and include its title and any series or reference number.
What should I do if a page I cited has disappeared?
First look for the same content elsewhere on the publisher’s site, since addresses change more often than content does. If it has genuinely gone, a reputable web archive may hold a dated snapshot you can cite as the archived version alongside the original details. If nothing verifiable remains, replace the source rather than cite something a marker cannot check.
