Use the responsible creator
A copyright owner, site host, and page author are not always the same. Prefer the credited author or the organization that actually publishes the content.

What belongs in an ACS website citation?
An ACS website reference identifies the specific page you used, not merely the website domain. The most dependable record begins with the person or organization responsible for the content, followed by the page title and the direct URL. A website name and publication or update date add useful context when the page provides them. These details help a reader return to the same source instead of landing on a broad home page or an unrelated search result.
The current ACS Style Quick Guide shows a concise website example built from an organization, page title, and URL. Real assignments and individual journals can request additional details, especially a publication date or the date you accessed changeable content. The generator therefore keeps website name, publication date, and access date visible but optional. It never invents a date or treats the date shown in your browser history as source metadata.
Use the page itself as your primary record. Look for a named author, a responsible organization, a clearly displayed title, and a published or last-updated date. Copy a clean, stable URL without campaign parameters or a search-session suffix. If the page is actually a journal article, report, dataset, or PDF with its own publication information, a more specific source type may describe it better than the general website form.
Reference anatomy
ACS website format, field by field
Include only metadata the page actually supplies. Optional information should strengthen identification, not fill space or imitate a different source type.
ACS / PATTERN
Author or organization. Page title. Website name, publication date. URL (accessed YYYY-MM-DD)
- 01
Author or organization
American Chemical SocietyUse a named author when one is credited. Otherwise enter the organization responsible for the page rather than guessing a person from the site footer.
- 02
Page title
ACS Publications Home PageCite the title of the specific page you consulted. Do not replace it with the browser tab label when that label contains unrelated site or navigation text.
- 03
Website and date
Compound Interest, April 23, 2023Add the larger website name and a publication or update date when clearly shown. Both are optional in this form and are omitted cleanly when unavailable.
- 04
Direct URL
https://pubs.acs.org/Use the stable address of the cited page. Remove tracking parameters when they are not needed to reach the content, and avoid a search-results URL.
- 05
Access date
(accessed 2026-07-20)Add an access date when your journal, course, or source type requires it or when the content is designed to change. The field uses an unambiguous ISO date.

Four checks
How to cite a website in ACS style
- 01
Confirm the source type
Make sure the item is truly a webpage rather than a journal article, book, report, dataset, or PDF that needs a more specific reference pattern.
- 02
Collect visible metadata
Record the credited author or organization, exact page title, website name, and publication or update date when the page displays them.
- 03
Clean the URL
Use the direct page address and remove unnecessary tracking or search parameters. Add an access date only when it is useful or required.
- 04
Preview and verify
Read the finished reference, open the URL once, and compare the entry with your course or journal instructions before adding it to the bibliography.
Accuracy notes
Website details worth checking
Webpages often expose less structured metadata than journal and book records. These checks help prevent a polished citation from pointing to the wrong or incomplete page.
Review the current ACS Style Quick GuideDo not invent a publication date
A footer copyright year, file download date, or browser visit date is not automatically the page publication date. Leave the optional field empty when uncertain.
Cite the page, not a search result
Open the result and copy its stable destination. Search-engine URLs and temporary session links can expire or lead readers to a different result set.
Check whether another format fits
A report or article remains that source type even when accessed through a browser. Use the format that describes the work, not simply the software used to read it.
Website FAQ
Common ACS website citation questions
01How do I cite a website in ACS style?
Start with the author or responsible organization, add the specific page title, then include the website name and publication date when available, followed by the direct URL. Add an access date when your instructions or the changing nature of the source calls for one.
02Does every ACS website citation need an access date?
Not every current ACS website example includes one. Some journals, instructors, and online source types still request an access date, so the generator keeps it optional and formats it only when you supply it.
03What if a webpage has no individual author?
Use the responsible organization when it is clear from the page. Do not infer a personal author from contact details or a site footer. If responsibility is genuinely unclear, consult the example required by your course or journal.
04Should I include the website name and page title?
The page title identifies the content you used, while the website name can identify the larger publication that contains it. The page title is required by this tool; the website name is optional because some concise examples do not need both.
05Can I paste any URL into the generator?
Use a public, stable URL that opens the cited page. Avoid search results, authenticated session links, shortened links with an unknown destination, and tracking parameters that are not needed to reach the content.
06Can I add website citations to an ACS bibliography?
Yes. Generate the website reference, choose “Add to bibliography,” and combine it with journal and book references. The tool preserves the order in which you add entries so you can match the order of first citation in your writing.
