If you have ever stared at a web page with no author name and no visible date and wondered how to cite it, you are not alone, and an in text website citation example built around those edge cases is exactly what you need. While many guides show perfect sources with a named author and a clear year, real websites are messier: pages are written by teams, updated silently, or published under an organisation name. This guide focuses on Chicago style, including its author-date system, and on the missing-author and no-date problems that cause the most confusion.
Chicago style actually offers two systems, and choosing the right one matters before you write a single citation. The notes and bibliography system uses footnotes or endnotes plus a bibliography, and it is common in history and the humanities. The author-date system uses brief parenthetical citations in the text plus a reference list, and it is common in the sciences and social sciences. This guide concentrates on author-date, because that is where in-text website citations live, but it notes where the notes system differs so you can adapt if your course requires footnotes instead.
An in text website citation example in Chicago Author-Date Style
In Chicago author-date style, the basic in-text citation gives the author surname, the year, and, for a quotation, a locator such as a paragraph number or section heading. A parenthetical citation looks like this: Daily walking improved mood scores across the study group (Reyes 2021). A narrative citation, where the author appears in your sentence, looks like this: Reyes (2021) found that daily walking improved mood scores across the study group. Notice that Chicago author-date uses no comma between the author name and the year, which is a small but reliable way to tell it apart from APA at a glance.
With two authors, both surnames appear, joined by and: (Reyes and Kim 2021). With three authors, Chicago author-date normally lists all three in the citation, unlike APA and MLA which shorten to et al. much sooner. With four or more authors, Chicago shortens to the first surname plus et al., as in (Reyes et al. 2021). These thresholds catch many writers out, because habits carried over from APA lead them to shorten three-author sources too early. When in doubt for a Chicago paper, check the author count rule rather than trusting another style’s habit.
For a direct quotation from a web page, Chicago needs a locator because web pages have no stable page numbers. You can use a paragraph number, a section heading, or both, for example (Reyes 2021, para. 3) or (Reyes 2021, under Benefits of Walking). For a paraphrase or summary, the author and year alone are enough. The reference list entry at the end then gives the full details, including the page title, the site name, the publication or revision date, and the web address.
An in text website citation example in the Notes System
Although the notes system does not use in-text parenthetical citations, it is worth understanding because many Chicago assignments require it. In the notes system, a superscript number in your sentence points to a footnote at the bottom of the page or an endnote at the end of the paper. The first note for a website gives the author, the page title in quotation marks, the site name, the publication or revision date, and the web address. Later notes for the same source are shortened to the author surname, a short title, and a locator.
For example, a first footnote for a fictional article might read: Maria Reyes, How Walking Changes Your Brain, Mind and Motion, last modified March 4, 2021. A shortened later note would read: Reyes, How Walking Changes Your Brain, para. 3. The bibliography entry then follows a slightly different order and punctuation. If your instructor asks for Chicago without specifying a system, ask which one they mean, because mixing footnotes with author-date parenthetical citations in one paper is one of the fastest ways to lose marks.
Missing Author: Who Counts as the Author?
A missing author is the most common website edge case. Before concluding that a page has no author, check four places: the top of the article near the headline, the bottom of the article near a byline or about note, the site about page, and the page footer. Many pages credit an editorial team or a department rather than an individual, and that team or department name can serve as the author. If a page is genuinely unsigned, Chicago does not leave the author slot blank. Instead, the organisation that publishes the site becomes the author.
For example, a health guide published by a national health agency with no individual byline would be cited under the agency name: (National Health Agency 2022). In the reference list, the agency name appears where the author would normally go. If even the publishing organisation is unclear, Chicago allows the citation to begin with the page title instead. A parenthetical citation then uses a shortened title, as in (How Walking Changes Your Brain 2021). The shortened title should be distinctive enough for the reader to match it to the reference list entry, so keep the most recognisable words and drop filler words at the start where sensible.
A Checklist for Unsigned Pages
Work through this checklist before treating a page as authorless. First, search the page for a byline, including small text near the top. Second, scroll to the end, where many sites place author credits. Third, look for an editorial or content team credit, which Chicago accepts as an author. Fourth, check whether the site itself, such as a government department or university, is the responsible publisher, and use that name. Only after all four steps fail should you fall back to a title-based citation. This discipline matters because citing an organisation when an individual author exists, or vice versa, makes your reference list harder to follow.
No Date: What to Do When the Date Is Missing
The second great edge case is the undated page. Websites are updated constantly, and some pages show no publication date at all. Chicago author-date handles this with the abbreviation n.d., meaning no date, placed where the year would normally go. A citation therefore looks like (Reyes n.d.) or, for a title-based citation, (How Walking Changes Your Brain n.d.). The reference list entry uses n.d. in the same position, and it should also include the date you accessed the page, because undated web content can change without notice.
Before using n.d., make the same kind of effort you made for the author. Check the top and bottom of the page for a published or updated stamp, look for a copyright year in the footer, and check the page metadata or revision history where the site provides it. A last updated date counts as a date for citation purposes in Chicago, and you should use the most recent revision date the page displays. Only use n.d. when no date of any kind can be found. If you find a copyright year but no article date, Chicago guidance generally treats the copyright year as a last resort rather than a publication date, so prefer an access date in the reference entry and note the situation honestly.
Why Access Dates Matter for Websites
Chicago recommends access dates for web sources, and they are especially important for undated or frequently updated pages. An access date tells your reader when you saw the version you are describing, which protects you if the page later changes. In author-date reference entries, the access date appears near the end, after the web address. It does not appear in the short in-text citation itself, so (Reyes n.d.) stays short while the reference entry carries the full access detail. Recording the access date on the day you read a source is a small habit that prevents a large amount of end-of-project detective work.
Combined Edge Cases at a Glance
The table below covers the combinations writers actually meet, including pages missing both an author and a date.
| Situation | In-text citation (author-date) | Reference list approach |
|---|---|---|
| Named author and year | (Reyes 2021) | Author, year, title, site, address |
| Two or three authors | (Reyes and Kim 2021) or all three surnames | List all authors in the entry |
| Four or more authors | (Reyes et al. 2021) | List authors per Chicago reference rules |
| Organisation as author | (National Health Agency 2022) | Organisation name in the author position |
| No author at all | (How Walking Changes Your Brain 2021) | Entry begins with the page title |
| No date | (Reyes n.d.) | Use n.d. and add an access date |
| No author and no date | (How Walking Changes Your Brain n.d.) | Title first, n.d., plus access date |
| Direct quotation, no pages | (Reyes 2021, para. 3) | Same entry; locator only in the citation |
How Chicago Differs From APA and MLA
Comparing styles helps you avoid cross-contamination when you switch between courses. APA puts a comma between author and year and uses an ampersand for two authors inside parentheses. MLA omits the year from in-text citations entirely and relies on the surname alone. Chicago author-date omits the comma, uses and rather than an ampersand, and lists three authors in full before shortening. These are tiny differences on the page, but markers notice them, and consistency within a paper matters more than any single rule. Pick the style your assignment requires and keep a one-page cheat sheet beside you while drafting.
Another difference is how each style treats the reference entry. Chicago reference entries include the access date for web sources more routinely than APA, which dropped routine retrieval dates for most stable web pages, and MLA, which includes access dates only optionally. If you are moving a paper from one style to another, do not just reformat the in-text notes. Rebuild the reference list too, because punctuation, capitalisation, and date placement all change. Readers who follow your citations will thank you for the extra care, even if they never consciously notice it.
A Practical Workflow for Tricky Websites
Start by capturing the source details the moment you decide a page is useful: author or organisation, title, date or last updated stamp, site name, and the page address for your own records. If the author or date is missing, note that fact immediately and record the access date, so you do not have to reconstruct it later. Draft your in-text citation from those notes, choosing the author, organisation, or shortened title form as appropriate. Then build the reference entry to match, checking that the first word of the entry matches the first element of your in-text citation. That matching rule is the single most useful self-check in citation work: if the in-text note starts with Reyes, the reference entry must start with Reyes, and if the in-text note starts with a title, the entry must start with that title.
For related citation problems, our guides to citations in appendices and citing quotations show how the same principles apply when a source appears in a less usual position. The underlying logic never changes: give the reader a short, accurate pointer in the text and a complete, findable entry at the end.
Frequently Asked Questions
Does Chicago use a comma between author and year?
No. In Chicago author-date citations, the form is (Reyes 2021) with no comma. This is one of the easiest Chicago rules to remember, and one of the most commonly broken by writers used to APA.
What if a page has neither an author nor a date?
Use a shortened title plus n.d., as in (How Walking Changes Your Brain n.d.), and give the full title, n.d., and an access date in the reference list entry.
Can a website name be the author?
Yes, when the organisation publishes the content and no individual is credited. Use the organisation name in the author position, and be consistent between the in-text citation and the reference entry.
Should I use footnotes or author-date citations?
Follow your assignment or publisher. History and many humanities subjects prefer notes and bibliography, while sciences and social sciences often prefer author-date. Never mix both systems in one paper.
Conclusion
Chicago website citations become manageable once you separate the normal case from the edge cases. Learn the author-date pattern of surname plus year with no comma, list three authors in full, and fall back cleanly to an organisation name, a shortened title, or n.d. when the page gives you less information. Record access dates for undated pages, keep your in-text notes matched to your reference entries, and check the author count rule before shortening any citation. With those habits, even the messiest web page can be cited correctly, and your reader will always be able to retrace your steps to the original source.
