Each of the links on this guide will take you to the Chicago Manual of Style, which will give you several examples for how to cite that item.
Citing information you find online can be tricky as it takes so many forms. The important thing to remember is that you have two goals in this process. First, to keep yourself from plagiarizing and give the original creator credit for their work, and two, to help your instructor or other reader of your work to find your original sources. So, do your best to provide all the information possible about a source formatted as best you can!
For a general webpage, Turabian does have a specific form. You'll need to locate as many of the following items as possible: author, date last updated, title of the page, title of the site, and owner/sponsor of the site.
If the author of the site and the owner/sponsor of the site are the same, you only need to use their name once in the author slot.
Blogs are cited slightly different than a normal website, as they are treated more like a typical article.
Social media is generally only cited in the text or in a footnote. So you won't need to include it on your Bibliography. Use your footnote to provide a link to the social media post, if possible.
If you're using a video or audio recording from the internet, try to include information about the original version when possible.
If you're using a journal article you found on the internet, see the Articles tab for how to format it. Do not use the regular website format!
If you're using an eBook, see the Books tab for information on how to format it.
