Google+ is one of the younger social media networks, but it's already surpassed Twitter and is on track to give Facebook a run for their money as well. Google lets you use a various array of buttons, from a +1 button you can use on any page, a badge to get people to follow you, a follow button, and finally a share button as well.
Google+ +1 button
Visit the Google+ +1 button page, and fill in all the details for your button.
Next copy the resulting code and paste it into your page.
You should now see your Google+ +1 button where you placed the code on your page:
Visit the Google+ badge button page, and customize your badge to your liking.
Then copy the resulting code you get and paste it into your page.
Now you'll see our new Google+ badge right beside our +1 button:
Google+ follow button
Visit the Google+ follow button page, and adjust the size and settings.
Then you'll want to copy the code and paste it into your page.
Now we've got a Google+ +1 button, a badge, and the new follow button we just created!
Google+ share button
Visit the Google+ share button page, and choose your settings.
Next you'll want to copy the code and paste it into your page where you'd like the button.
Now we've got our Google+ +1 button, a badge, a follow button, and the new share button we just created!
