CHICAGO 18TH EDITION GUIDE
Chicago Website Citation: 18th Edition Format & Examples
To cite a webpage in Chicago 18th edition, identify the author or responsible organization, page title, website owner or sponsor, relevant publication or revision date, and URL. If the page has no publication or revision date, Chicago recommends an access date for a formal citation, or you can cite a publicly archived version when appropriate.
SHORT ANSWER
Chicago also makes an important point: not every webpage needs a formal citation. For ordinary web content, it can sometimes be enough to identify the page naturally in your text. Use a formal note, bibliography entry, or Author-Date reference when the source needs fuller documentation. Need a citation now? Use the Chicago Citation Generator to paste a webpage URL, review the metadata retrieved from the page, correct anything incomplete, and generate either Chicago citation system.

What information do you need to cite a website in Chicago style?
For a typical webpage, look for:
- individual author, when one is credited;
- organization responsible for the content, when appropriate;
- page or article title;
- website title, section, owner, or sponsor when relevant;
- publication date;
- revision, effective, or last-modified date when that is the meaningful date;
- access date if no publication or revision date exists;
- URL;
- archived URL when citing a preserved version.
Do not assume every field will be present.
Webpages often expose incomplete or inconsistent metadata, which is why automatically retrieved source details should be reviewed before you use the citation.
Do you always need to formally cite a webpage in Chicago style?
No.
Chicago’s official 18th-edition examples state that it is often sufficient simply to describe a webpage or other website content in the text.
For example, a sentence might identify:
- the organization;
- the page or policy;
- the relevant date;
- the information being discussed.
A formal citation becomes more useful when:
- the webpage is an important research source;
- readers need a durable way to identify it;
- your instructor or publisher requires formal source documentation;
- the page contains a quotation or substantive evidence;
- the source belongs in your bibliography or reference list.
Do not create a bulky bibliography entry merely because a URL appears somewhere in your paper.
How do you cite a webpage in Chicago Notes & Bibliography?
In Chicago Notes & Bibliography, a webpage may appear in a note and, when appropriate, in the bibliography.
The exact order depends on what information the page provides.
Chicago’s official examples show that a note often begins with the page title, while a bibliography entry is normally organized under the owner or sponsor of the site when that is the appropriate responsible body.
Official example: dated policy page
Full note
“Privacy Policy,” Privacy & Terms, Google, effective November 15, https://policies.google.com/privacy.
Shortened note
Google, “Privacy Policy.”
Bibliography
Google. “Privacy Policy.” Privacy & Terms. Effective November 15, 2023. https://policies.google.com/privacy.
The note and bibliography entry do not simply repeat the same fields in the same order.
How do you cite a webpage in Chicago Author-Date?
In Chicago Author-Date, the author or responsible organization and year create the short in-text citation.
Official example
In-text citation
(Google 2023)
Reference list
Google. 2023. “Privacy Policy.” Privacy & Terms. Effective November 15. https://policies.google.com/privacy.
If the webpage has no publication or revision date, use n.d. in place of the year and include an access date in the reference-list entry.
Chicago website citation format at a glance
Because webpage metadata varies, there is no single template that fits every site perfectly.
A practical starting point is:
Notes & Bibliography
Full note
“Page Title,” Website/Section or Responsible Organization, publication/revision information, URL.
Shortened note
Organization or Author, “Shortened Page Title.”
Bibliography
Organization or Author. “Page Title.” Website/Section if needed. Publication/revision information. URL.
Author-Date
In-text
(Organization or Author Year)
Reference list
Organization or Author. Year. “Page Title.” Website/Section if needed. Publication/revision information. URL.
For undated pages, replace the year with n.d. and include the access date.
Who is the author of a webpage?
Use the actual credited creator or responsible body, not whichever name happens to be easiest to find.
A webpage may have:
- an individual author;
- several individual authors;
- an organization as author;
- no clearly identified author.
Individual author
If a page clearly credits a person, use that person as the author.
Do not replace the individual author with the website name merely because the site belongs to an organization.
Organization author
An organization can serve as the author when it is responsible for the content and no more appropriate personal author is given.
Examples can include:
- government agencies;
- universities;
- companies;
- professional organizations;
- museums;
- research institutes;
- nonprofit organizations.
No clear author
If no author is identified, do not invent one.
In Notes & Bibliography, the page title may lead the note.
In a bibliography or Author-Date reference list, the site owner or sponsor may sometimes be the appropriate leading element if it is clearly responsible for the content.
Always review the actual page and its credits.
What is the difference between website author, website name, owner, and sponsor?
These terms can overlap, but they are not automatically the same thing.
Consider a page on a university website:
- page author: the person who wrote the page, if credited;
- page title: the title of that specific webpage;
- site owner/sponsor: the university or department responsible for the site;
- website name: the broader site or section in which the page appears.
Chicago’s webpage examples often organize bibliography entries under the owner or sponsor when that is the useful identifying entity.
Do not repeat the same organization mechanically several times if it would add no useful information.
The purpose of the citation is to identify the source clearly and concisely.
What date should I use for a webpage?
Use the date that best describes the version of the page you consulted.
Depending on the site, that might be:
- publication date;
- revised date;
- last-modified date;
- effective date.
Chicago’s official webpage examples include:
- effective dates for policies;
- last modified dates for pages that change over time.
Do not assume the copyright year in the website footer is the publication date of the page.
A site-wide footer such as:
© 2026
usually tells you about the website’s copyright notice, not necessarily when the specific page was written or revised.
What if a webpage has no publication or revision date?
If a webpage has no publication or revision date and a formal citation is needed, Chicago recommends including an access date.
Notes & Bibliography official example
Note
“About Yale: Yale Facts,” Yale University, accessed March 8, 2022, https://www.yale.edu/about-yale/yale-facts.
Bibliography
Yale University. “About Yale: Yale Facts.” Accessed March 8, 2022. https://www.yale.edu/about-yale/yale-facts.
Author-Date
In-text
(Yale University n.d.)
Reference list
Yale University. n.d. “About Yale: Yale Facts.” Accessed March 8, 2022. https://www.yale.edu/about-yale/yale-facts.
Here, n.d. means “no date.”
Do not use n.d. simply because the generator did not find a date automatically. Check the visible page first.
When should I include an access date?
An access date is particularly useful when:
- the webpage has no publication or revision date;
- the content is expected to change;
- your instructor or publisher requires access dates;
- you are citing a live page that cannot otherwise be tied to a particular version.
You do not need to add an access date automatically to every webpage.
If the page has a clear and relevant publication, revision, effective, or last-modified date, use that information instead unless your required style variation says otherwise.
Can I cite an archived version of a webpage?
Yes.
Chicago 18 explicitly allows a publicly available archived version from the Internet Archive’s Wayback Machine or a similar service to be cited.
An archive is useful when:
- the page changes frequently;
- the current live page no longer matches what you consulted;
- the page has disappeared;
- you want readers to be able to see the historical version you used.
Official-style example
Yale University. “About Yale: Yale Facts.” Archived March 8, 2022, at a Wayback Machine URL.
If you cite an archived version, make sure the archive really preserves the version relevant to your research.
Do not create an archive date from memory.
Should I archive a webpage before citing it?
Not every webpage needs to be archived, but archiving can be valuable for unstable or frequently changing material.
Chicago’s current Q&A specifically recommends preserving a version of a website home page when it matters because home pages are designed to change.
Good candidates for archiving include:
- home pages;
- policies that change;
- dashboards;
- announcements;
- organizational pages that are frequently updated;
- pages likely to disappear;
- web-only evidence central to your argument.
If the current version of the page is stable and adequately dated, an archived version may add little value.
How do you cite a website home page?
A home page usually does not need a bibliography entry.
Chicago’s 18th-edition Q&A recommends that a home page normally be mentioned in the text or a note rather than treated automatically as a bibliography source.
A home page is also unlikely to have the literal title “Home Page.”
If a formal citation is necessary, use an accurate description when no meaningful page title exists.
Because home pages change frequently, include an access date when citing the live page or cite an archived version when the historical state matters.
Do not invent a quoted title such as “Home Page” if that is not actually the page’s title.
How do you cite a webpage with an individual author?
If a webpage clearly credits an individual author, use that author.
A general Notes & Bibliography structure can look like:
Full note
First Name Last Name, “Page Title,” Website or Organization, date, URL.
Shortened note
Last Name, “Shortened Page Title.”
Bibliography
Last Name, First Name. “Page Title.” Website or Organization. Date. URL.
Author-Date
In-text
(Last Name Year)
Reference list
Last Name, First Name. Year. “Page Title.” Website or Organization. Date details if needed. URL.
The exact formatting depends on what kind of content the page actually is.
If the page is really a news article, magazine article, blog post, or another distinct publication type, use that source type instead of forcing it into a generic webpage template.
How do you cite a webpage with an organization as author?
When the organization is responsible for the content, it can occupy the author position.
Chicago’s official examples include:
- Google;
- Wikimedia Foundation;
- Yale University.
Notes & Bibliography
Google. “Privacy Policy.” Privacy & Terms. Effective November 15, 2023. https://policies.google.com/privacy.
Author-Date
Google. 2023. “Privacy Policy.” Privacy & Terms. Effective November 15. https://policies.google.com/privacy.
In-text
(Google 2023)
The organization name should match the entity actually responsible for the page.
Do not automatically use a website’s parent company when the page identifies a more specific organization or individual.
Can I abbreviate a long organization name in Author-Date citations?
Chicago Author-Date allows recognizable abbreviations for organization authors in appropriate cases.
For a long organization name that appears repeatedly, an abbreviation can make text citations easier to read.
The full reference-list entry should make the organization’s identity clear.
Do not invent obscure abbreviations that readers will not recognize.
If the organization appears only once or twice, spelling it out may be clearer.
How do you cite a webpage that changes over time?
First determine whether the page provides:
- effective date;
- revision date;
- last-modified date;
- publication date.
Use that version information when it meaningfully identifies the content you consulted.
If the page changes but gives no useful date:
- include an access date;
- consider citing an archived version.
For very dynamic pages, identifying the exact version can matter more than it does for a stable published article or book.
What if the webpage has a “last updated” or “last modified” date?
Use a last-modified date when it represents a meaningful revision of the page.
Chicago’s official example for Wikipedia includes:
last modified December 19, 2023, at 21:54 (UTC)
This level of precision is useful for pages that change frequently and provide a precise modification timestamp.
Do not add a time zone or exact time unless the page actually supplies it and the precision is useful.
Should I use the copyright date at the bottom of the website?
Usually not as the page’s publication date.
A copyright footer often applies to the site as a whole and may update automatically every year.
It does not prove that a specific article, policy, FAQ, or informational page was written or revised that year.
Prefer:
- visible page publication date;
- updated date;
- effective date;
- last-modified information;
- access date when no date is available.
Do I include the website name if it is the same as the author?
Repetition is sometimes unavoidable, but avoid adding redundant information that does not help identify the source.
If the author name and website identity are essentially the same, the citation may still repeat them when the roles are genuinely distinct.
Chicago’s current Q&A confirms that a webpage citation can legitimately contain similar author and site-name information when each identifies a different citation element.
The goal is clarity, not the mechanical elimination of every repeated word.
How do you cite a blog post?
A blog post is web content, but it is not always best treated as a generic webpage.
Chicago groups news sites, magazines, blogs, and similar article-like sources together for citation purposes.
A blog post often has:
- named author;
- post title;
- blog title;
- specific publication date;
- URL.
If the source clearly behaves like an article or blog post, cite that content type rather than using the generic webpage pattern.
This launch site does not yet have a separate Chicago blog-post citation page, so the Chicago Citation Examples page can provide broader examples while this guide focuses on ordinary webpages.
Is a news article on a website a “website citation”?
Not for citation-format purposes.
If you read a New York Times, Washington Post, Wired, or similar article online, the source is still a news or magazine article, not merely a generic webpage.
The URL describes how you accessed it.
The content type determines the citation structure.
Do not remove:
- article author;
- publication title;
- publication date;
and replace them with a generic website template.
A dedicated newspaper citation guide may be added in a later phase if keyword research supports it.
Is an online journal article a webpage citation?
No.
A scholarly journal article remains a journal article even when you read it through a browser.
Use:
- journal title;
- volume;
- issue;
- page range or article ID;
- DOI;
where applicable.
See the Chicago Journal Article Citation guide.
The fact that an article has a URL does not turn it into a generic webpage.
Is a PDF on a website a webpage citation?
Not necessarily.
Ask what the PDF is.
It might be:
- a journal article;
- report;
- book;
- book chapter;
- conference paper;
- government publication;
- thesis;
- ordinary web document.
Cite the underlying source type rather than automatically citing “the PDF.”
The file format is not the same as the publication type.
The generator’s PDF workflow currently attempts to identify a DOI from a PDF when one is available and then performs normal metadata lookup. It should not be treated as guaranteed full bibliographic extraction from every PDF.
How do you cite a policy page?
A policy page may have an effective date rather than a conventional publication date.
Chicago’s official example for Google’s privacy policy uses:
effective November 15
rather than inventing a publication date.
Use the date label the source actually gives when it meaningfully describes the version.
For legal, regulatory, or institutional policies, accuracy about the version can be particularly important.
How do you cite a Wikipedia page?
A Wikipedia page changes over time, so version information matters.
Chicago’s official webpage example uses the page title, Wikimedia Foundation, a last-modified date and exact time, and the URL.
For research where the exact historical version matters, citing a permanent revision or archived version can be more useful than citing only the live page.
Also follow your instructor’s policy on whether Wikipedia is acceptable as a source for the assignment.
How do you cite a government webpage?
Treat the government agency or responsible office as the author when that is appropriate, unless an individual author is clearly credited.
Look for:
- agency name;
- page title;
- publication/update date;
- report or document number if the source is actually a report;
- URL.
Do not force a government report into the generic webpage format when the source is formally published as a report or document.
The publication type still matters.
How do you cite a university webpage?
A university, department, research center, or other unit can serve as the responsible organization when no individual author is credited.
The official Chicago examples use Yale University as the leading organization for an undated webpage.
If the page is produced by a specific department or center, use the level of organization that most clearly identifies responsibility for the content.
Do not automatically list the university as both author and website title several times.
Do webpages need page numbers?
Most ordinary webpages do not have stable page numbers.
Do not invent them.
If the page provides stable:
- paragraph numbers;
- section headings;
- numbered sections;
- anchors;
one of those may sometimes serve as a useful locator when a specific citation needs it.
For Notes & Bibliography, a locator can be added to the citation occurrence when appropriate.
For Author-Date, a non-page locator can follow the year when needed.
Use only locators that actually exist in the source.
Can I cite a section heading instead of a page number?
Yes, when a section heading is the most useful stable locator and page numbers are unavailable.
This can be especially useful for:
- long webpages;
- online documentation;
- ebooks;
- web-based reports.
Do not treat a section heading as part of the permanent source metadata when it only identifies the passage you are citing.
The Chicago Citation Generator separates citation-level locators from the source record for this reason.
Do I include “https://” in a Chicago website citation?
Yes, a normal web URL should be presented as a usable URL.
Chicago 18 also expanded guidance on shortened URLs, but do not shorten a link merely to make it visually prettier if the shortened version becomes unreliable or obscures the destination.
Avoid tracking parameters and unnecessary session information when a clean canonical URL is available.
Use the page URL that reliably identifies the source.
Should I remove UTM parameters from a citation URL?
Usually, yes, when they are merely tracking parameters and the clean URL reaches the same content.
For example, prefer a stable page URL over a link containing advertising or campaign parameters such as:
?utm_source=...
Do not remove query parameters that are actually required to identify the page, search state, document, or version.
The goal is a stable, functional citation URL.
What if the webpage URL is extremely long?
Use the shortest stable URL supplied by the site when possible.
Chicago 18 includes expanded guidance on shortened URLs.
Prefer:
- canonical URL;
- official short link;
- DOI where the source is actually a DOI-based publication;
- stable archive URL when citing an archived version.
Do not use a third-party URL shortener simply to make the bibliography look cleaner unless the shortened link is reliable and appropriate.
Should I hyperlink the page title instead of printing the URL?
In digital publishing, a publisher may choose to link the title or another part of the citation.
For academic manuscripts and general citation output, showing the URL explicitly remains useful unless your required style or publication workflow specifies linked titles instead.
The citation should remain identifiable even if hyperlinks are lost in plain-text export.
How many authors do I list for a webpage in Chicago 18?
Chicago 18 applies its general author thresholds across source types.
Notes and Author-Date text citations
- one author: list the author;
- two authors: list both;
- three or more: first author + et al.
Bibliography and reference list
- one to six authors: list all;
- more than six: first three + et al.
Many webpages instead have an organization author, but when multiple personal authors are credited, use the current Chicago 18 thresholds.
See Chicago 18th Edition for the broader author-rule changes.
What changed for website citations in Chicago 18?
The basic webpage principles remain centered on identifying the responsible source, title, date/version information, and URL.
Several broader 18th-edition changes still matter:
Author thresholds changed
Notes and Author-Date text citations now list up to two authors before using first author + et al. Bibliographies and reference lists list up to six before switching to first three + et al.
Mentioning vs formally citing sources received expanded guidance
Chicago 18 added guidance distinguishing a simple mention of a source from a formal citation.
This matters especially for ordinary website content, which often does not need a full bibliography entry.
Shortened URL guidance was expanded
Chicago 18 gives more guidance on using shorter, cleaner URLs where appropriate.
Shortened note forms were clarified
When a webpage has already been established, shortened notes may use author-title, author-only, or title-only forms when the context is clear.
For all major citation changes, see Chicago 18th Edition: What Changed.
What are the most common Chicago website citation mistakes?
Treating every online source as a webpage
A journal article, news article, ebook, report, social-media post, or video keeps its own source type even when accessed through a browser.
Inventing an author
Do not turn the publisher, website, or domain owner into the author without evidence.
Using the footer copyright year as the page date
A site-wide copyright notice is not usually the publication date of the individual page.
Adding an access date to every webpage
Access dates are especially useful for undated or unstable content, not a compulsory field for every web citation.
Using n.d. without checking for a date
Look for publication, revision, effective, or last-modified information first.
Omitting the access date for a genuinely undated page
For a formal citation to an undated webpage, Chicago uses an access date.
Citing the live page when a historical version matters
Use an archived version when the page has changed and the version you consulted matters to your claim.
Calling a home page “Home Page” when that is not its title
Use a description if a formal citation is necessary and the page lacks a meaningful title.
Inventing page numbers
Most webpages do not have stable page numbers.
Keeping tracking parameters in the URL
Use a clean stable URL when the extra parameters are not necessary.
Trusting scraped metadata blindly
Web metadata is often incomplete. Confirm the author, page title, website owner, date, and URL against the visible page.
Describing PDF import as full webpage extraction
The generator’s PDF feature identifies a DOI when possible and then performs normal lookup. It does not guarantee complete bibliographic extraction from every PDF.
Chicago website citation: Notes & Bibliography vs Author-Date
| Feature | Notes & Bibliography | Author-Date |
|---|---|---|
| Main citation | Footnote/endnote | Parenthetical author-year |
| Undated source | Access date in formal citation | n.d. + access date |
| Full source list | Bibliography when appropriate | Reference list |
| Organization author | Can lead bibliography entry | Used in author-year citation |
| Revision/effective date | Included where relevant | Year supports text citation |
| Archived version | Can be cited | Can be cited |
| URL | Full citation | Reference-list entry |
If you are unsure which citation system your assignment requires, start with the Chicago Style Guide.
How to generate a Chicago website citation
The Chicago Citation Generator supports webpage URL lookup.
1. Paste the webpage URL
The generator attempts to retrieve available metadata from the page.
Depending on the website, that may include:
- title;
- author;
- organization/site information;
- date;
- URL;
- other common web metadata.
2. Review the retrieved metadata
This step is particularly important for webpages.
Check the visible page for:
- credited author;
- responsible organization;
- page title;
- relevant website/section name;
- publication or revision date;
- effective or last-modified information;
- correct canonical URL.
Automatic webpage metadata can be incomplete or misleading.
3. Correct or complete the source record
If the page has no date, do not invent one.
If a formal undated webpage citation requires an access date, add the real date you accessed the page.
4. Choose the Chicago system
The source can be rendered as:
Notes & Bibliography
- Full Note
- Shortened Note
- Bibliography Entry
Author-Date
- In-Text Citation
- Reference List Entry
5. Add a locator if needed
If a long webpage has a real section, paragraph number, or other useful locator, add it to the citation occurrence without changing the permanent webpage metadata.
6. Copy or save the citation
Copy the citation you need or add the source to your bibliography/reference-list project.
For a transparent explanation of webpage retrieval, normalization, CSL formatting, source storage, and known limitations, see How the Chicago Citation Generator Works.
Is URL lookup always accurate?
No.
Websites expose metadata in different ways.
A page may provide useful:
- Open Graph metadata;
- HTML meta tags;
- author fields;
- structured metadata.
Another page may expose very little.
Common problems include:
- no author;
- site name mistaken for page author;
- title truncated or duplicated;
- footer date mistaken for publication date;
- JavaScript-generated content unavailable to simple metadata retrieval;
- incorrect canonical URL;
- updated page with stale metadata.
Review the page itself before using the citation.
The generator intentionally makes retrieved metadata editable rather than treating automatic lookup as unquestionable.
Need to cite a different source type?

Frequently asked questions
How do I cite a website in Chicago style?
Identify the author or responsible organization, page title, relevant website or sponsor information, publication/revision date when available, and URL. If no publication or revision date exists, include an access date for a formal citation.
Do I need to cite every website formally?
No. Chicago says it is often sufficient to describe ordinary website content in the text. Use a formal citation when the source needs fuller documentation or your assignment requires it.
What if a website has no author?
Do not invent one. Use a responsible organization when appropriate, or let the page title lead where Chicago’s format calls for it.
What if a website has no date?
In Author-Date, use n.d. and include an access date in the reference-list entry. In Notes & Bibliography, include the access date in the formal citation.
Do I need an access date for every website?
No. Access dates are especially useful for undated or changing pages, or when your instructor or publisher requires them.
Can I cite the Wayback Machine?
Yes. Chicago allows a publicly archived version of a webpage to be cited when that version is useful.
How do I cite a website home page?
Usually mention it in the text or a note rather than automatically placing it in the bibliography. If a formal citation is necessary, use an accurate description rather than inventing the title “Home Page,” and consider an access date or archived version.
Is the website name always the author?
No. Use the individual author when one is credited, or the responsible organization when it functions as the author.
Can a company or university be the author?
Yes, when the organization is responsible for the content.
Should I use the copyright year at the bottom of the site?
Usually not as the page publication date. Look for a page-specific publication, update, effective, or last-modified date.
Is a news article on a website cited as a webpage?
No. Cite it as a news or magazine article. The URL identifies online access, but the source type remains an article.
Is an online journal article a website citation?
No. Cite it as a journal article using journal metadata such as volume, issue, pages/article ID, and DOI.
Is a PDF automatically a website citation?
No. Identify whether the PDF is a report, article, book, thesis, or another source type and cite that underlying publication type.
Can I use a section heading instead of a page number?
Yes, when the page has a real stable section heading and that locator helps the reader find the cited material.
Can the generator cite a webpage from a URL?
Yes. It can retrieve available webpage metadata from a URL, but you should review and correct the returned source information before using the citation.
