Like Google +1 button Google+ share button is available in four annotations: 1. None 2. Bubble Horizontal 3. Bubble Vertical 4. Inline. It is also available in three different sizes: 1. Small 2. Medium 3. Large.

But when you add this button to your blog or site that is on Blogger and have more than one post on home page then this button shares home page not the posts. So in this article I will cover how to add a Google+ share button on Blogger blogs which will be valid for each post not only to home page. For this purpose we’ll modify default Google+ share button code. Let proceed to modification:

Default Google+ share button code:

<!-- Place this tag where you want the share button to render. -->
<div class="g-plus" data-action="share" data-annotation="bubble"></div>

Modified Google+ share button code:

<!-- Place this tag where you want the share button to render. -->
<div class='g-plus' data-action='share' data-annotation='bubble' expr:data-href='data:post.url'/>
