Load Google+ Button Asynchronously For Faster Loading Times
Webmasters have little choice but to add the Google+ button and other social networking buttons to their websites. Why? Because social signals will grow in importance in the coming years. These buttons can also be convenient for site visitors who would like to share a specific article or the whole website that they just discovered with friends, family or colleagues.
Webmasters who would like to integrate the new button need to visit the Google +1 button generator at Google to generate the code for the new button.
Update: it appears that the generator is no longer available. You still find the code to integrate it on your website there.
The code for the old +1 button was placed in two locations. First at the location on the page where the button should show up and second in the site's footer just before the closing body tag.
Webmasters who do not want or cannot integrate the new code into their website will benefit from rendering optimizations which can speed up the rendering of the button on a website by a factor of 3. This is automatic and independent of the button code that is implemented on the site. Additional information about the speed improvements are available on the Google Webmaster Central blog.Advertisement
