Ernie and I had a discussion about this earlier. What do you typically put in the Author Meta tag (your name, your client’s name, the company name, etc.) or do you simply leave it blank?
I looked into this recently and added a meta tag for authors, which links to a humans.txt file that has to be uploaded separately. Since the site I am working on is for myself obviously there is no client but in that case I think you would list both.
