Publishing to your Google+ Pages is now possible via our Campaign Manager. Just like you were able to post to many social networks already. Same tracking, same reporting - roi and conversion analytics.
In case you are already managing your Google+ Page with Social Report, there is one thing you will need to do first:
1) Login to your account
2) Open up a project
3) Click on 'Add Account' and re-add your Google+ pages to the project.
That's it. Once you do that, this page will show up in the list of available publication targets.
Let us know if you have any questions!
