Google, the search engine giant, has decided to do the unthinkable – Challenge Facebook’s Like button. Yesterday (June 28) Google +1 made its debut all around the globe.

“Today, +1’s will start appearing on Google search pages globally,” Google Product Manager Nick Radicevic announced on Google’s AdSense blog. “We’ll be starting off with sites like google.co.uk, google.de, google.jp and google.fr, then expanding quickly to most other Google search sites soon after.”

Google has built partnerships with several large publications such as The Telegraph, El Pais, The Independent, SnapDeal, and Last.fm.

According to Mashable, Google launched the +1 button last month as an attempt to increase its presence on the web. The button acts much like the Facebook Like or Twitter Tweet button. The company says it may use +1 data as a signal for improving search results in the future. The button, which debuted in March in Google search, will compete with the likes of the already ubiquitous sharing buttons offered by Facebook and Twitter (and more recently Tumblr and LinkedIn) for web page real estate.

“If +1 doesn’t succeed, Bing, Yahoo, Blekko, and anyone else who can establish partnerships with Facebook – the established social medium – will get a leg up on social search, a vital part of how information will be found in the coming years,” states Rob D. Young of Search Engine Watch.
