We use one running example throughout — a page published by an organisation:
Author/organisation: World Health Organization · Date: 2 March 2023 · Page title: Adolescent mental health · Site: WHO · URL: who.int/news-room/fact-sheets/detail/adolescent-mental-health
The anatomy of a web reference
A website citation is built from the same shape as any other source — who, when, what, where — but two of those slots are often missing online, which is what makes web sources feel harder than they are. The full set of facts is: the author (a person or an organisation), the date the page was published or updated, the title of the page, the name of the website as a whole, the URL, and — in several styles — the date you accessed it. When a fact is genuinely absent, the styles have specific rules for what to do, covered below; you never simply leave a gap or invent a detail.
Where to find the details
Look first for a named author in a byline; if there is none, the organisation that runs the site is the author. The date is often near the top or bottom of the article, or in a "last updated" line — be careful to distinguish a publication date from a copyright date in the footer, which is usually just the current year. The page title is the heading of the specific page, while the website name is the publication or organisation as a whole. The URL should be the address of the specific page, not the homepage. Gather these, decide which are genuinely missing, and you are ready to format.
APA 7
APA gives the organisation as author, the full date, the page title in italics, the site name, and the URL:
In-text: (World Health Organization, 2023). APA needs an access date only for pages designed to change (e.g. a live map). See our APA guide.
MLA 9
MLA puts the page title in quotation marks and the website in italics, with the date and URL:
In-text: ("Adolescent Mental Health"). See our MLA guide.
Harvard
Harvard (Cite Them Right) gives author–date, then "Available at:" and an access date:
In-text: (World Health Organization, 2023). See our Harvard guide.
Chicago
In Chicago's Notes–Bibliography system the page appears as a footnote (and, if needed, a bibliography entry):
See our Chicago guide.
Vancouver
Vancouver numbers the source, tags it "[Internet]", and gives a "[cited]" date and "Available from:":
See our Vancouver guide.
IEEE
IEEE uses a bracketed number, an "Accessed" date and the "[Online]. Available:" tag:
See our IEEE guide.
No author or no date
These are the cases that make websites feel difficult, but each has a clear rule.
No named author: the organisation behind the site is the author. If the organisation is also the site (as with the WHO example), you avoid repeating the name and can begin with the page title instead. Never list a web page as "Anonymous" — there is almost always an organisational author.
No date: use "n.d." (no date) where the year would go in APA and Harvard — for example (World Health Organization, n.d.) — and lean on the access date to record when you consulted the page. The combination of "n.d." plus an access date tells the reader honestly that the page itself was undated and when you read it.
No page numbers (almost always, online): for a direct quotation, cite a paragraph number, a section heading or a timestamp instead of a page — (World Health Organization, 2023, para. 3).
Access dates, explained
An access date records the day you read a page, and it exists because web content changes or disappears. The styles disagree on when you need one: Harvard and Vancouver generally require an access date for web sources; APA and MLA require one only for pages designed to change over time (a live statistics dashboard, a wiki, a social feed) and omit it for stable pages. The safe rule for students is to include an access date whenever you are unsure — a marker rarely penalises its presence, but often penalises its absence where the style expects it. For a source with a permanent identifier such as a DOI, you do not need an access date at all, because the identifier guarantees the same version.
Is the page even citable?
Before you spend time formatting a web citation, ask whether the page is a source worth citing. A page with no author, no date and no identifiable organisation behind it is a warning sign: it may not be credible enough for academic work, whatever the referencing rules allow. Favour pages from governments, established organisations, universities and recognised publications, and treat anonymous blogs, content farms and AI-generated pages with caution. Citing a weak source correctly does not make it a strong source — and markers notice the quality of your evidence as much as the accuracy of your references. Our guide on academic integrity says more about using sources responsibly.
Getting the in-text citation right
Web sources make the in-text citation feel awkward precisely because the elements an in-text marker normally uses — an author and a year — are often the things missing online. The rules are nonetheless clear. In the author–date styles, you cite whatever sits in the author position, which for most web pages is an organisation: (World Health Organization, 2023). When the page has no author and you have begun the reference with its title, you cite a shortened form of that title instead — ("Adolescent Mental Health") in MLA. When there is no date, "n.d." takes the year's place — (World Health Organization, n.d.). The numbered styles, Vancouver and IEEE, sidestep the problem entirely by using a figure, so the missing author and date are handled in the reference-list entry rather than in the sentence.
Quoting from a web page raises one more issue: there are usually no page numbers. For a direct quotation you therefore point the reader to a paragraph number, a section heading, or a timestamp instead — (World Health Organization, 2023, para. 3). Counting paragraphs feels fussy, but it is what lets a reader find the exact words you quoted on a long, unpaginated page, and it is exactly the kind of precision that distinguishes careful web referencing from a vague gesture at a URL.
A four-step method for any web page
Approached methodically, even a messy web source becomes routine. Step one: identify the author. Look for a byline; if there is none, the organisation running the site is the author. Resist the urge to write "Anonymous" — there is nearly always an organisational author behind a page worth citing. Step two: find the real date. Look for a dated byline or a "last updated" line, and ignore the footer copyright year; if there is genuinely no date, plan to use "n.d." plus an access date.
Step three: capture the page title, the site name and the specific URL — the address of the page itself, not the homepage — and decide, from your style, whether you need an access date. Step four: assemble the reference using the pattern for your style from the examples above, then add the matching in-text citation and check the two agree. The fourth step is also the moment to pause and ask the credibility question below: a page that has forced you to write "no author, n.d." at every step is sending a signal about whether it belongs in an academic essay at all. Running this routine consistently means you never freeze at a web source again — you simply work through the four steps and accept the agreed markers where a detail is genuinely missing.
When a page changes or disappears
The deepest problem with web sources is that they are not fixed: a page you cite today may be edited, moved or deleted tomorrow, taking your evidence with it. This is the reason styles ask for an access date in the first place — it records the version you actually read — but an access date does not bring back a page that has vanished. For sources you rely on heavily, or that seem likely to change, it is worth taking a more robust approach.
The most practical safeguard is web archiving. Services such as the Internet Archive's Wayback Machine capture snapshots of web pages as they appeared on a given date, and you can both consult an existing snapshot and create a new one yourself. Several citation styles allow — and in some cases prefer — that you cite the archived snapshot's stable URL rather than the live page, precisely because the snapshot will not change. If a marker later checks your reference, the archived version shows exactly what you saw, on the date you saw it, which protects you if the original has since been altered or removed.
At the very least, when you cite an important web page, save a copy — a PDF print of the page, or a screenshot — at the moment you read it, and note the date. This is not paranoia; it is the same instinct that makes you keep a copy of your own submitted work. A reference is a promise that a reader can find the source you used, and for the shifting medium of the web, a little archiving is what keeps that promise honest. It also quietly improves your judgement about which sources to trust: a page worth archiving is usually a page worth citing, while one you would not bother to preserve may not belong in your essay at all.
Common mistakes to avoid
- Listing a page as "Anonymous" instead of using the organisation as author.
- Using the footer copyright year ("© 2024") as the publication date.
- Giving the homepage URL instead of the specific page's address.
- Omitting an access date where Harvard or Vancouver requires one.
- Adding an access date in APA for a stable page that doesn't need one.
- Inventing a date or author rather than using "n.d." or the organisation.
- Citing an anonymous, undated page that isn't credible enough for academic work.
Gather who, when, what and where; apply the no-author and no-date rules when a slot is empty; and add an access date when your style expects one. Do that and even the trickiest web source becomes routine. When research draws on many online sources and the deadline is close, our writers will reference each one correctly in your required style.
Frequently asked questions
How do you cite a website with no author?
Move the organisation behind the site into the author position; if the organisation is also the site, begin with the page title instead. Never use "Anonymous".
How do you cite a website with no date?
Use "n.d." (no date) where the year would go in APA and Harvard, and rely on the access date to record when you read it.
Do you need an access date?
Harvard and Vancouver usually require one; APA and MLA require it only for pages likely to change. Include it when in doubt.
