An article in APA referencing a blog can be done in a few different ways. The most common way is to simply use the author’s last name followed by “blog.” For example, if the author’s last name is Smith and their blog is called “Smith Blog,” then the reference would be “Smith Blog (2008).” Another option is to use the full url of the blog, including the http:// part.
For example, if the blog’s url is “http://smithblog.blogspot.com,” then the reference would be “Smith Blog (2008).” If a blog has changed its URL since the article was written, then it can be referenced using the old URL followed by a hyphen and the new URL, like this: “Old URL-New URL.”.
