With Google+, you can make it easy for people to connect with your content and share your site with the people who care about it.
- Add the Google +1 button to your site. The +1 button is the easiest and most lightweight way for users to recommend your content and (optionally) share it with their circles.
- Add the Google+ Share plugin to your site.
In general, we recommend adding the +1 button to your content. However, there are some circumstances in which users might want to share a piece of content without implicitly +1’ing it. The content might be sensitive or controversial, or it might be temporary (like an offer or event).
- Link your site and your Google+ page
- Customize the +snippet text displayed when your content is shared
- Get detailed metrics about +1 activity, your +1 audience, and the impact of +1 on your search traffic
