In Chicago style, you must cite sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:

Webpages can be problematic to cite because, unlike books or journals, they are edited frequently and don't have an actual "publication date." If you can locate a publication date or date of revision or modification, use that. If a publication or revision date cannot be located, use the date you accessed the website.
Note-Bibliography
Note:
Note #. First-name, Last-name, "Title of Webpage," Website Name, Access-Date, URL.
Example:
18. “Style Guide,” Wikipedia, Accessed July 18, 2008, https://en.wikipedia.org/wiki/Style_guide.
Short Note:
Note #. Last-name, "Title Words."
Example:
23. "Style Guide."
Bibliography:
First-name, Last-name. "Title of Webpage." Website Name. Publication/Revision/Access-Date. URL.
