Google has always focused on the relevance factor of the search results. It adds that relevance is about relationships as well as words on webpages.Google has gone a step ahead on the social scenario by adding a +1 button to the search results which enable you to recommend a search result right on the SERPs itself.
The +1 button will appear next to each search result
If you cannot see the +1 button then visit Google Experimental, where you can select an option to force it to appear in your searches.
When you click +1 you publicly give something your stamp of approval or recommend it. Your +1’s can help friends, contacts, and others on the web find the best stuff when they search.
In order to +1 things, you first need a public Google profile. This helps people see who recommended that tasty recipe or great campsite. When you create a profile, it’s visible to anyone and connections with your email address can easily find it.
Your +1’s are stored in a new tab on your Google profile. You can show your +1’s tab to the world, or keep it private and just use it to personally manage the ever-expanding record of things you love around the web.
