Have you linked your WordPress to your Google+ account through the ‘sharing’ settings option, and only realized that all of your posts are ‘shared privately’ on Google+ after you made, like, 20 of them? Join the club, and find out how to fix this ‘shared privately’ setting!
While you can’t change the privacy settings on an item that has already been published on your Google+ page, you can make sure all of your posts are ‘public’ in the future.
First, make sure your Google+ page is connected to your WordPress account by adding it to your ‘sharing’ settings.
You will either see a pop-up, or be taken to a Google+ page, both of which will ask you if WordPress has your permission to share your posts on your chosen Google+ profile or page. Confirm you would like to grant this permission, and you will be redirected back to your WordPress ‘sharing’ options page.
A pop-up will ask if you’d ‘like to make this connection available to all users.’ If you have multiple administrators, authors or editors as part of your blog, they can all benefit from this connection, and their posts will share on the connected Google+ page. This is the only capability other users will have; this connection does not allow these other users to directly access your Google+ page or your stored Google information.
Confirm you would like to grant this permission, and the ‘connection’ will appear on your WordPress ‘sharing’ page.
By default, the WordPress application you have just installed on your Google+ page or profile is set to publish posts privately, the viewing option labeled ‘Only Me.’ In order to fix this, you must change the settings in your Google+ account ‘settings.’
Return to your Google+ page and access your ‘Settings’ menu.
Once in ‘settings,’ scroll halfway down the page until you see ‘Apps & activities / Manage your apps and Activity Log, including who can see your Google and third-party activities.’ Click the ‘Manage Apps + Activities’ button, and you will be taken to a page with your applications and other items.
Under the ‘Apps’ tab, you will now see a WordPress icon and, across from it, your chosen application visibility – it has been automatically set as ‘Only Me.’ Click the ‘edit’ button beside this option, and select the new option ‘Public,’ and save your settings. (You can also be more selective and choose a different share option from the dropdown menu.)
And voila! Now, all of your future WordPress posts sent to that Google+ page will be public and viewable by all.
