Google recently launched support for rel=author markup to associate authors with online content and verify authorship. This allows authors to claim work, increasing engagement and lending reputation/exposure to personal brands. To implement, authors create a Google+ profile matching their byline, add profile details and websites they contribute to. They then add their Google+ link to blog profiles and individual posts. Authors can test setup using Google's Rich Snippets tool to check attribution is working.

2. Google recently announced their support for the rel=author markup which
will allow us to associate authors with articles wherever they are published
online.

• This way Google verify the ownership and authenticity of the
content building trust in the link.
• This builds credibility for you and also increase the CTR (click
through rates) of your links.
• Allow authors to claim their work and a stable authority within
their industry.
• Increases engagement between authors and readers.
• It can lend reputation and increased exposure of your personal
brand.

3. How it looks in SERP

4. How to get start?
• First you need a Google+ profile account. If you don’t have
then create new one.
• Go to https://plus.google.com and create a new account with
your own name.
• Make sure your byline name matches the name on your
Google+ profile.
• Add your photo and complete the profile page. The more you
add, the better
• Make sure you have a profile photo with a recognizable
headshot.

below in that same box and Save.
<a href="https://plus.google.com/110451025019330326815?rel=author">Google+</a>

9. In the same way, if you have multiple authors in your blog page, then create google+
profiles of each author and follow the same process.
If you need an author bio at the end of every post, then you can simply use a plugin : WP
Biographia. (see the image below)

plugins by checking disable / enable buttons.

address of your domain to link your content to G+ profile.

but at some point you can
start checking individual posts
to see if your efforts have
been successful.
You do this by using the
Google Rich Snippets Testing
Tool (See the image)
Paste a URL of a post into the
box and click preview to get a
report that indicates if the
search engine would attribute
the post to you.

12. If the post has been successful set up for rel=author, you will get output like the
