How do I use APA Citation Style

A guide with examples for references and in-text citation

APA Citation Style - 7th edition

All examples in this guide are using APA Citation Style (7th) edition 

If you need help with the 6th edition, please visit Purdue OWL.   If you have any further queries, please email


When citing website, always make sure you know what you are looking at.  If the item is traditionally published in print (book, journal article, magazine, report, dissertation, etc.), refer to the online version of the style for that item (e.g. ebook, online magazine, etc.).  Some websites, however, are truly just websites (and are not online surrogates of print publications).  For websites that cannot be classified under a formal category, use the following standard format:

Author, A. A./Group. (YYYY, Month dd). Title of webpage. Title of website. URL

Note the following:

  • The title of the webpage is italicized.  The name of the website, itself, is not italicized.  
  • If the website or format of the web content is special in any way, include the description or format in brackets after the title.
  • If there is no date associated with the exact page (do not use the copyright date for the whole site), then indicate "no date" with (n.d.). for the date portion of the reference. 
  • If the author and the site name/publisher are the same, omit the website name from the reference.

Social Media

Social media posts have additional rules for APA Style. 

  • Only include text of the social media post up to the first 20 words.
  • Retain hashtags, links and replicate emojis, if possible.  If emojis are not available, describe the emoji in square brackets (e.g. [praying hands emoji].  Each emoji counts as one word.
  • Note any audiovisuals associated with the post in square brackets after the text of the post.  Some common descriptions include: [Facebook page], [Highlight], [Image attached], [Infographic], [Online forum post], [Photograph], [Status update], [Thumbnail with link attached], [Tweet], [Twitter profile], [Video].

Blog Post

One unusual exception to how web pages are cited is the 7th edition's rules for 'Blog Posts.'  Blogs are considered periodicals (like journals and magazines). In this case, the article title is NOT italicized, but the site name IS italicized.  


Blog Post (Section 10.1)

The use of electronic resources must comply with the Appropriate Use of Electronic Resources Policy and Singapore Management University Acceptable Use Policy
