Have you noticed how some sites get the author profile photo alongside of the Google search results?

The way to do this is to establish a Google+ profile and upload a photo of yourself.

Then add a code snippet to your content pages that links the author to your Google+ account.

Then add your domain to your Google+ profile as a site that you contribute to.

Then you stand a chance to enhance your search result listings with your profile pic. which could attract more clicks and lead to people exploring more of your sites.

And later, it may become a factor in SEO e.g. social proof that you don't make crap sites
