Google+ badges were introduced to promote Google+ pages. Now Google is providing more options to integrate Google+ badge into your website. This provides the flexibility to configure the badge with the desired width to fit your website design and choose the one that works with site background.
Also the badges will now include the +1 and the circle count.
As Google says "We recently looked at top sites using the badge and found that, on average, the badge accounted for an additional 38% of followers. When you add the badge visitors to your website can discover your Google+ page and connect in a variety of ways: they can follow your Google+ page, +1 your site, share your site with their circles, see which of their friends have +1'd your site, and click through to visit your Google+ page."
