Google also launched a plugin for a built-in +1 button. The button is installed in the top right hand corner of the browser, right next to the Facebook Like button is both plugins are installed. In order to use the button, the user needs to log into a Google account. After logging in, only a single click is needed to +1 a page. Google did not announce the plugin on the official blog and it’s surprising that +1 functionality hasn’t been seen in the continually updated versions of Chrome. While over 14,000 people have installed the +1 button (compared to around 500 for that Facebook Like button), building +1 into Chrome would reach millions of Chrome users upon the next update of the browser.
Google has made it clear that the +1 button isn’t being used to track user behaviour when surfing the Internet. While Google retains some information about visitors for maintenance and debugging, there’s no categorization based on the personal details of the profile like name, age or gender. In addition, the information is deleted approximately two weeks after a user visits a site.
