You will have to have a google account and google profile (see example) to be able to see this on search engine results click here to get a profile
Google+1 can only be see by users of google chrome all the time and when you are logged into google.
When you +1 something, your name becomes associated with that link “in search, on ads, and across the web,” according to the company. It also shows up in a feed on your Google Profile, which is required to use the product.
The move builds on a number of social features that Google introduced in search earlier this year, such as the ability to see which friends have tweeted a given link in search results. Today’s move, however, is clearly something much bigger.
Beyond showing up in search results, Google plans to offer to publishers a +1 button that lets readers +1 something without leaving the publisher’s site. Facebook has a big head start here with its Like button — some 2 million sites and counting have it installed — but Google’s button will instantly have a lot of appeal, given the company says +1 data will directly influence its market share dominating search rankings. Similarly, we have to imagine that +1 is more bad news for content farms, whose content is less likely to be shared.
In another twist, users will also be able to +1 ad, which essentially adds a “recommended by friends” component to AdWords and AdSense. as the company explains on the AdWords blog.
