How to cite a website in Vancouver
A web page or online article. Numbered style used across biomedical journals.
Quick answer
To cite a website in Vancouver, include the author(s), year, title, and container or publisher details. A concrete example is below.
Example

What you need
For a website, Vancouver expects these fields at minimum:
- Author or organization
- Year of publication
- Page title
- Website / organization name
- URL
- Access date (some styles)
Common mistakes
- Citing a dynamic page without an access date — crucial because the content can change.
- Using the URL as the title. The title is the page heading; the URL is a separate field.
- Mixing bibliography formatting with in-text citation rules. Reference-list entries and in-text cites follow different patterns — use the style's official guide for both.
- Forgetting the DOI. When a DOI exists, most styles now require it (usually as a full https://doi.org/… URL).
