If you are producing content, then setting up Google Authorship is a must for your business. Google launched authorship markup as a way to connect authors with their web content. 

When someone has authorship set up correctly, you will see their photo and their name next to their content, along with a content description. Their name is a clickable link that helps you find other content the author has written.

• It provides a much more appealing search engine entry (great for SEO) and makes your content more visible in search results. Author images and links get more clicks than other search results. 
• It builds authority by linking your name to the content you write.
• It helps build trust among web users, and also improves brand recognition. If people associate your avatar with excellent content, that’s good for business.

• Increased Click-through Rate in Search Engine Results Pages

• Better SEO

Google loves ranking content readers value highly. By having a high click-through rate, you show Google that visitors are interested in your website's content. Consequently, Google will rank you higher the next time one of your blog posts appears in an SERP.

•  Company Branding

If you connect a Google+ business profile with your company's logo as the profile picture to your website with Authorship, then you can get your company's logo displayed in the SERPs. So, even if search engine users don't click on your listing, they still see your logo and are exposed to your branding.

• Personal Branding

• Featuring a personal photo of you as the profile picture, you'll get personal branding benefits -- more people will see your face and be able to recognize it in the future.More Google Followers

One of the steps in setting up Google Authorship is placing a link from a webpage to your Google+ profile. The placing of that link increases the likelihood that visitors to your website will view your Google+ profile as well, which translates into more followers.

• Increased trust

All blog readers -- no matter who they are -- like to know that the content they're reading was created by a real person they can connect with, not just a faceless mask behind a computer. By showing your personal picture in the search results, you build trust and rapport with your readers even before they visit your site.
