Punit Soni, lead product manager for Google+ Games and Mobile, said this should help people around the Web make recommendations even while on the go.
“The button will automatically be visible to anyone on Android 2.1+ and iOS 4.0+ browsers. When you +1 something, it will be displayed publicly across the Web as an annotation on the content you +1’d," Soni said in a Google+ post.
Soni added that with the +1 button available on the mobile web, a user with an Android or iOS device can tap to +1 directly from his or her mobile phone or tablet.
The +1 button allows one to start conversations by publicly recommending pages across the web, or share with the right circles on Google+.
Google said the +1’s can help improve its search too, “since you can see which pages your social connections have +1’d right beneath search results and ads." — LBG, GMA News
