What you need
For a social media post, Chicago (author-date) expects these fields at minimum:
- Author (handle or display name)
- Full date
- Text of the post or description
- Platform name
- URL
Common mistakes
- Mixing bibliography formatting with in-text citation rules. Reference-list entries and in-text cites follow different patterns — use the style's official guide for both.
- Forgetting the DOI. When a DOI exists, most styles now require it (usually as a full https://doi.org/… URL).
- Inconsistent capitalization. APA uses sentence case for titles; MLA and Chicago use title case. Mixing them is the single most common style error.
