Final answer:
When citing a blog post orally, exclude the page number or reference number, and include author's name, post title, blog name, post date, and URL.
Step-by-step explanation:
When orally citing a blog post, it is not necessary to include a page number or reference number, as this is generally required for works that contain multiple pages or sections. Blogs are typically one continuous page, and with the advent of digital tools like the CTRL + F function, locating information in an online source has become much more straightforward. Readers can quickly find what they need by searching for keywords or phrases. Therefore, essential details when citing a blog would include the author's name, the title of the post, the name of the blog, as well as the date of the post and the URL. For example, an oral citation could be abbreviated to just mentioning the author's last name if it's available or the title of the blog post if the author is not listed.
