How to Cite Websites, Online News and Social Media Posts in AMA Style

Printed journals are the backbone of medical referencing, but a growing share of what students and clinicians cite lives online: health agency pages, news articles, organisational reports and even social media posts. AMA style (from the AMA Manual of Style, 11th edition) has clear rules for each. Getting them right shows readers exactly where to find a source and when you accessed it, which matters because web content changes.

The basic website format

A standard AMA web reference contains:

In template form:

Author AA. Title of page. Name of website. Published Month Day, Year. Updated Month Day, Year. Accessed Month Day, Year. URL

Example:

National Health Agency. Understanding high blood pressure. National Health Agency website. Updated January 5, 2026. Accessed March 3, 2026. https://www.example.org/high-blood-pressure

(The agency and page are illustrative.) Notes on this example:

When dates are missing

Many web pages don't show a publication date. In AMA style, include the accessed date regardless; it's the reader's clue to which version you saw. If there's an "updated" or "last reviewed" date, include it as well.

Online news articles

News articles follow a similar pattern, with the publication name italicised as it is for newspapers:

Author AA. Title of article. Name of Newspaper. Month Day, Year. Accessed Month Day, Year. URL

Example:

Smith J. Hospital waiting lists fall for third month. The Example Times. February 12, 2026. Accessed February 20, 2026. https://www.example.com/news/waiting-lists

(The example is illustrative; always cite real sources you've read.)

Reports from organisations

Reports, guidelines and fact sheets published online by agencies and charities use the website format, with any report number included after the title:

World Health Organization. Global Report on Hypertension. WHO; 2023. Accessed April 2, 2026. URL

Longer standalone documents, like books, are typically italicised; shorter pages are not. When in doubt, follow the pattern of the closest example in the manual.

Social media posts

AMA style allows citing social media when it's the original source of information, such as a public health agency's announcement:

Author (@handle). Text of post, up to the first 10 words or so. Platform. Month Day, Year. Accessed Month Day, Year. URL

Keep the account handle, quote the start of the post accurately and include the post's date. Consider whether a more permanent source, like a press release, would serve readers better.

Formatting rules to remember

Checking a reference list

Web references are where most errors creep in: missing accessed dates, inconsistent capitalisation, or organisation names written two different ways. A reference builder like amacitationgenerator.org can lay out each element in the right order, but always compare the output with the source page and correct capitalisation and author names by hand.

Quick checklist

Summary

AMA web references follow a consistent pattern: author, page title, site name, dates and URL. The accessed date is essential because online content changes. Treat news, reports and social media as variations on that pattern, and double-check every generated reference against the original source.
