The +1 button in Toolbar lets you start great conversations on the web. When you click the button, you're publicly recommending pages across the web. +1’s can help improve Google Search too, since you can see which pages your social connections have +1'd right beneath search results and ads.
When you +1 something, the +1 button on the Toolbar turns blue to confirm that you've recommended the page. Your +1 will be added to the +1s tab on your Google Profile. Go to your profile to manage all your +1’s and toggle the display the +1’s tab. Learn more about managing your +1's in the Google+ Help Centre.
