The + Snippet is made from the image, the title and the description, more descriptive and compelling these information are and the more chances that you go and read the post! If the eye wants its part, you give it to him!
 
Google provides the code to set image, title and description of the + Snippet in Google Plus, a very powerful tool!
 
To understand what happens when you press the button, Google +1 look at this video:
 
 
 

 

Google uses various types of markup (they are codes to be entered in the html of the post) to set + Snippet, and are taken into account in the following order:
  • Schema.org
  • Open Graph Protocol
  • Title and Description
Google sets everything automatically
So if there is no markup Schema.org on your blog and you have the Open Graph Protocol catch values ​​from the information passed through the Open Graph code, and so on ...

Schema.org

It 's the method preferred by Google, but not necessarily to be the easiest to implement!
Here's how to set the image, the title and the description of a post:
<body itemscope itemtype="http://schema.org/Article">
<h1 itemprop="name">Titolo del post</h1>
<img itemprop="image" src="immagine-di-anteprima.jpg" />
<p itemprop="description">Descrizione dell'articolo.</p>
</body>

Open Graph Protocol

It 's the protocol used by Facebook & Co, gives the properties page for the image, the title and the description, using these codes to be entered before closing of the tag </ head>:

 

<meta property="og:title" content="Titolo del post"/>
<meta property="og:image" content="Immagine di anteprima"/>
<meta property="og:description" content="Descrizione del post"/>

Title and Description

Using the classic html code.
You must enter these two lines of code before the closing of the '</ head> tags in the html code:
 
<meta name="title" content="Titolo del post" />
<meta name="description" content="Descrizione del post" />

To specify the image always insert before the closing of the </ head>:

 

<link rel="image_src" href="url-immagine.jpg" />

Google sets everything automatically

 

If you do not have any of previous markup, first implements at least one!
However, without any markup, Google will automatically set the image, the title and the description of the post, but here you have no control over the quality of the result!
 
One final observation: it happens that after inserting or updating your markup by pressing the +1 button, the preview of the article in your profile page +1 can be different from the snippet, a problem that will be solved in a few days, when Google delete the cache.
 
Finally, to see in action what I described in the post and to understand its potential, share this post on Google+ using the +1 button on the side!
