Google+ for Page

Add the Google+ Badge or Icon to your website to increase engagement and create a lasting connection with your audience.

This plugin allows you to place a widget on your sidebar that displays the official Google+ badge. You can choose to show either the Standard or Small size badge, and you can show as many different badges on a page or post as you choose – each with their own configuration.
You can also show a Google+ badge using template tags in your theme files or in a page or post using the simple shortcode (See FAQs for instructions).
NOTE: Google+ only allows this type of badge for a Google+ page and not a personal Google+ profile, so this plugin will only work for Google+ business pages.

Google+ Page Badge

Show one or multiple Google+ badges for your G+ page in a widget, using a shortcode, or with template tags.
