Well, not by default. Atleast not yet. You will have to join their experiment to make +1 buttons appear in the search results. For those who don’t know it already, Google has launched a rival to Facebook‘s "Like" button, called +1 (Plus One), whereby you can ‘plus one‘ search results (and very soon, content on website and blogs) that you like.

To enable +1 buttons in search results, you need to login to your Google account, enable +1 experiment here and then perform search on Google.com/ncr. You can not only +1 search results, but ads too.

+1 essentially replicates Facebook‘s "Like" button functionality right within search results. It allows you to vote up a search result which is then displayed next to the result to anyone in your Google network i.e your Gmail and GTalk contacts and the ones who follow you on Buzz. Soon, the internet giant will roll out buttons to be installed on websites and blogs. Your votes through these buttons will also reflect in search results. Google‘s idea to make search more ‘social’ seems cute but going by Google‘s performance in the social networking department (Yes, Buzz I am looking at you), I seriously doubt +1 to come anywhere close to Facebook’s "Like".

Google‘s +1 will be helpful (at least to some extent) to someone whose social circle is formed of people with similar likes. In other words, if I am a programmer, it’s natural that most of my searches will be programming related. If I have a good circle of programmer friends connected with me through Gmail / Gtalk / Buzz and who have already actively used +1 buttons in search, only then the service would be of any real help to me.

The present structure of Google profiles and social circle is not capable enough to make +1 a huge success. It’s boring too and Google knows that. Hence says, "Soon we may also incorporate other signals, such as your connections on sites like Twitter, to ensure your recommendations are as relevant as possible." Well, better incorporate that fast, Google.
