The Google+ badge has graduated out of preview today, be one of the
first to put it on your site! For those who’ve already added the code,
this means all users will be able to see the badge starting today.
Featuring both an ‘add to circle’ and a ‘+1’ button, the Google+ badge
helps you grow your audience on Google+ while also showing more
recommendations on Google Search.
If you have linked your Google+ page to your site, the count of +1s on
the badge will represent the +1s across your brand including those
from your home page, your Google+ page, and any ads you’ve linked via
Social Extensions.
Please note, once you’ve linked your Google+ page to your site, there
may be a delay before the count shown on the badge includes +1s from
across your brand. During this delay, the badge will show the count
of +1s from your Google+ page.
Get your Google+ badge with the badge configuration tool:
