Since Google launched its +1 button for websites this past June, it says that more than one million sites use the sharing feature . To extend the use of the button, Google recently launched two more features that enable users to use +1 buttons with their Google+ circles, and the ability for content publishers to customize the +1 content using what Google calls “+Snippets.”
These features are available on +1 buttons posted on subscribing sites, such as MakeUseOf (see the end of this article).
When you see the new “Share on Google +” option on a webpage, you can click it and choose one of your Google+ circles to instantly share that page, similar to how you share webpage links on your Twitter account. You can also add a comment in the sharebox before clicking the sent button.
For web content providers using +1 buttons, Google has has included what is called +Snippets, which is a way for publishers to customize the descriptions and linked image that pop-up in the sharebox. More details on customizing are available on the Google Webmaster blog.
In a related story, Google has said that it is exploring using +1 buttons as part of its search results algorithm for ranking websites. It told Wired magazine that “the purpose of any ranking signal is to improve overall search quality. For +1′s and other social ranking signals, as with any new ranking signal, we will be starting carefully and learning how those signals are related to quality“.
