Why Online Sources Cause the Most Referencing Errors
Books and journal articles follow tidy templates. Online sources do not. A website might have no author, no date, and a title that changes between your first visit and submission day. A YouTube video might be uploaded by a channel name rather than a person. A tweet might be the only evidence for a claim, and you have no idea how to cite it. Small wonder that online sources are where Harvard referencing most often goes wrong — and where markers most often deduct marks that were easy to keep.
The good news is that Harvard treats online sources with the same basic logic as everything else: author, year, title, and enough detail for your reader to find the source again. The differences are in the details — the URL, the access date, and how you handle missing information. If you need the foundations first, our Harvard referencing guide for students covers in-text citations and reference lists in general.
The Basic Website Template
For an ordinary web page with an author or organisation behind it, the reference list entry looks like this:
Author surname, initial. (Year) Title of page. Available at: URL (Accessed: Day Month Year).
A real example:
World Health Organization (2023) Mental health in the workplace. Available at: https://www.who.int/teams/mental-health-and-substance-use (Accessed: 12 September 2026).
Three details do most of the work. First, the author is often an organisation, not a person — use its name exactly as it appears on the site. Second, the year is the year the page was published or last updated, usually found at the bottom of the page; if there is genuinely no date, use (n.d.), as explained below. Third, the access date is not optional decoration: web pages change, move and disappear, and the access date tells your marker when you saw the version you are citing.
The in-text citation follows the usual Harvard pattern: (World Health Organization, 2023). Nothing special. The complications only start when information is missing, which happens constantly online — see the section on that below.
Blogs and Online Newspaper Articles
Blog posts and online newspaper articles use the same skeleton, with one addition: the name of the blog or newspaper goes in italics, and you include the day and month of publication, because online content is dated precisely.
The template:
Author surname, initial. (Year) ‘Title of article’, Blog or Newspaper Name, Day Month. Available at: URL (Accessed: Day Month Year).
An example:
Rakich, N. (2020) ‘How does Biden stack up to past Democratic nominees?’, FiveThirtyEight, 28 April. Available at: https://fivethirtyeight.com/features/how-does-biden-stack-up-to-past-democratic-nominees/ (Accessed: 29 April 2020).
Note the punctuation habits that markers check: the article title takes single quotation marks, not italics; the publication name takes italics, not quotation marks. Getting those two the wrong way round is one of the most common errors in student reference lists. Scribbr’s guide to referencing websites in Harvard style shows the same templates for blogs, newspapers and magazines side by side.
YouTube Videos and Other Online Video
Videos are cited much like web pages, with the uploader in the author position. If the video was uploaded by an individual, use their name in the usual format. If it was uploaded by a channel or organisation, use that name as it appears on the platform.
The template:
Uploader surname, initial. or Channel name (Year) Title of video. Day Month. Available at: URL (Accessed: Day Month Year).
An example:
Scribbr (2020) What is plagiarism? 23 January. Available at: https://youtu.be/Uk1pq8sb-eo (Accessed: 14 May 2020).
One useful feature: if you quote a specific moment, add a timestamp to the in-text citation — (Scribbr, 2020, 1:58) — which works like a page number for sources without pages. Use it when the video is long; for a short video, the citation alone is enough. The same pattern covers Vimeo, Instagram video and other platforms: uploader, year, title, date, URL, access date.
Social Media Posts
Social media posts are the source students are most tempted to leave out of the reference list entirely, usually because the format feels awkward. Cite them anyway — an uncited tweet is still an uncited source.
The template:
Author surname, initial. [username] (Year) ‘Text of post’ or title. [Platform] Day Month. Available at: URL (Accessed: Day Month Year).
An example:
Dorsey, J. [@jack] (2018) We’re committing Twitter to help increase the collective health, openness, and civility of public conversation … [Twitter] 1 March. Available at: https://twitter.com/jack/status/969234275420655616 (Accessed: 11 May 2020).
Three habits to copy: write the username exactly as it appears; use the post’s text in place of a title when there is no title, trimming long posts with an ellipsis; and name the platform in square brackets. If you only know the username and not the person’s real name, use the username alone in the author position — that is correct, not a shortcut. And a word of caution: social media is a weak source for most academic claims. Cite it when the post itself is the evidence — a politician’s statement, a company’s announcement — not as a substitute for peer-reviewed research.
Podcasts and Images Found Online
Two more formats that turn up regularly in student work. For a podcast, cite the individual episode, not the whole series, and include the word [Podcast] in square brackets:
Carlin, D. (2017) The destroyer of worlds [Podcast]. 24 January. Available at: https://www.dancarlin.com/hardcore-history-59-the-destroyer-of-worlds/ (Accessed: 11 May 2020).
Timestamps work the same way for podcasts: (Carlin, 2017, 25:55) points to the exact moment.
For an image found online — a photograph, infographic or artwork — include the medium in square brackets:
Taylor, P. (2020) Grey squirrel [Photograph]. Available at: https://flic.kr/p/2iZBKhY (Accessed: 11 May 2020).
Images carry a trap beyond referencing: copyright. Citing an image correctly is not the same as having permission to reproduce it — if it is not your own and not openly licensed, check your university’s guidance before including it.
When Information Is Missing
Online sources routinely lack an author, a date, or both. Harvard has a rule for each gap, and using the rule beats inventing the missing detail. Anglia Ruskin University’s Harvard guide is one of the clearest free references for these edge cases.
No author. Look for a corporate author first — the organisation behind the site. A page on a charity’s website is authored by the charity; a government statistics page is authored by the department. Only when there is genuinely no organisation either, use the title in the author position: (‘Divest’, 2020) in text, with the title first in the reference list entry.
No date. Use (n.d.), short for “no date”, in both the in-text citation and the reference list: (Scribbr, n.d.). Keep the access date — it becomes even more important when there is no publication date, because it is the only time marker the entry has.
No title. This is rare, but it happens with some data pages and dashboards. Use a short descriptive title of your own in square brackets, and explain what the source is in your text.
Whatever is missing, never invent it. A guessed year or made-up author is a fabrication, treated far more seriously than a correctly formatted (n.d.).
Common Mistakes With Online References
Dropping the access date. Every online reference needs one. No exceptions, no matter how stable the site looks. Government pages get redesigned too.
Pasting bare URLs in the reference list. A URL is not a reference. It tells the reader where the source is, not what it is, who wrote it, or when. If your reference list contains a line that is only a link, it is unfinished.
Mixing up italics and quotation marks. Article titles in single quotes, publication and website names in italics, video and podcast titles in italics. One consistent system, applied every time.
Citing the homepage instead of the page you used. Link to the specific article or page, not to the site’s front page. Your reader should land on the source, not have to hunt for it.
Forgetting the in-text half. A reference list entry with no matching in-text citation — or a citation with no entry — is an orphan, and orphans are one of the first things markers notice. Every online source cited in text must appear in the list, and vice versa. Our guide to avoiding plagiarism explains why that matching matters beyond mere neatness.
Your Pre-Submission Checklist
- Every website, video, post and podcast cited in text has a matching reference list entry.
- Every online entry includes a URL and an access date.
- Organisation names used as authors where no individual author exists; (n.d.) used where no date exists — nothing invented.
- Article titles in single quotation marks; publication, video and podcast titles in italics.
- Links point to the specific page, not the homepage.
- One Harvard style throughout — no stray footnotes or numbered entries mixed in.
Online sources are not harder to reference than books. They are just messier, and mess rewards a system: author, year, title, URL, access date, applied the same way every time.
