Google released its Google +1 (“a.k.a plus one”) button to compete with Twitter’s Tweet button and Facebook’s Like button. First, if you have a Google account, you can join the +1 button experiment to start voting and rating sites. Then you can incorporate the +1 button into your Blog to let users and visitors vote for your site.
You can join this experiment by clicking here. Make sure you’re signed into your Google Account. Click ‘Join this experiment’. Search for something you love on Google.com. Click the new +1 button, and make your mark on the web.
Please note, this experiment is browser-specific. From within each browser that you want to +1 from, you will need to repeat steps 1-2. Also, it may take a while before you see the button in search results, and it may occasionally disappear as we make improvements. Your feedback will help us make it better!
To add the +1 button into your blog, just go here and follow the steps. Then paste the code into your blog. If you are not used with code, just add a text widget in WordPress (Appearance -> Widgets) and paste the code there. If you are more used to editing your source code, you can paste the code at the bottom of each article, so people can vote easier for every new article you write.
The +1 button let people who love your content, recommend it on Google search. Enjoy!
