Is there a way to +1 something via a URL, just like you would with Twitter or Facebook?
e.g.
With Twitter you have:
http://twitter.com/home?status={url}
With Facebook you have:
http://www.facebook.com/sharer.php?u={url}&t={title}
With Digg you have:
http://digg.com/submit?phase=2&url={url}&title={title}
This is new, it was just posted by Google: Doing more with +1 button:
beginning today, we're making it easy for Google+ users to share webpages with their circles, directly from the +1 button. Just +1 a page as usual and look for the new "Share on Google+" option.
So how do you do this? Use +Snippets
When you share content from the +1 button... we automatically include a link, an image and a description in the sharebox. We call these "+snippets"
The real details are here, on the Google Webmaster Central blog: making the most of improvements to Google +.
The +1 button now lets visitors share links to your pages on Google+.
Example code containing each of the +Snippet attributes:
<body itemscope itemtype="http://schema.org/Article">
<h1 itemprop="name">This is the article name</h1>
<img itemprop="image" src="thumbnail.jpg" />
<p itemprop="description">This is the description of the article.</p>
</body>
The article suggests using what it calls the configuration tool for +snippets There are several input parameters, but the simplest example was
<!-- Update your html tag to include the itemscope and itemtype attributes -->
<html itemscope itemtype="http://schema.org/Article">
<!-- Add the following three tags inside head -->
<meta itemprop="name" content="Title Of Your +1 Content">
<meta itemprop="description" content="This would be a description of the content your users are +1ing">
<meta itemprop="image" content="images/cool-image.png">
You can share something via the following URL, as per the documentation:
https://plus.google.com/share?url={url}
or alternatively
https://plusone.google.com/_/+1/confirm?url={url}&title={title}
This is the Google+ equivalent to the Facebook and Twitter methods you’ve posted above. Unfortunately, this won’t +1 the link, only share it. I’m not very clear on the exact difference between these two actions, since the above actually loads a page which says
You publicly recommended this as {your name here}
– which sounds awfully like +1’ing. However, submitting the page verifiably only shares the link on Google+, it doesn’t add it to the person’s “+1’s”.
