Don't have an email address on the same domain as your content? Follow the instructions listed in Option 2 below.
Check that you have a email address (for example,
levy@wired.com) on the same domain as your content (wired.com).
Make sure that each article or post you publish on that domain has a clear byline identifying you as the author (for example, "By Steven Levy" or "Author: Steven Levy").
Visit the Authorship page and submit your email address to Google. No matter how many articles or posts you publish on this domain, you only need to do this process once. Your email will appear in the Contributor to section of your Google+ profile. If you want to keep your email private, change the visibility of your link.
To see what author data Google can extract from your page, use the structured data testing tool.
