A few months ago we released the +1 button on English search results on google.com. More recently, we’ve made the +1 button available to sites across the web, making it easy for the people who love your content to recommend it on Google search.
Today, +1’s will start appearing on Google search pages globally. 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.
We’ve partnered with a few more sites where you’ll see +1 buttons over the coming days.
If you’re a publisher based outside of the US, and you’ve been waiting to put +1 buttons on your site, now’s a good time to get started. Visit the +1 button tool on Google Webmaster Central where the +1 button is already available in 44 languages.
Adding the +1 button could help your site to stand out by putting personal recommendations right at the moment of decision, on Google search. So if you have users who are fans of your content, encourage them to add their voice with +1!
