The best way to direct visitors to your Google+ profile or content page is to use a Google+ Profile Button. Google has provided Google+ Profile Buttons generator tool which can give you a cut and paste code easily.
Google+ Profile Buttons
Visit the Google+ Profile button page and you can grab Google profile buttons in various sizes, have an option to link to your content or profile page.
What is your profile url? We visit https://profiles.google.com and it redirects to https://plus.google.com/106735197389068740217/posts (this will only happen if you have a Google+ account). So either we can use that url or use this profile link https://plus.google.com/106735197389068740217/ which will also redirect to the same page. You can choose to send visitors to your content or author info page.
Note the code also has the author markup recently introduced by Google built in. So if you select Author page, then the rel=”me” gets in, and if you select content page, then rel=”author” get incorporated. This will help show your profile in Google search results. Also note Google has strict branding guidelines and you cannot alter the Google+ logos, need to link to your profile and display the button clearly.
