Creating a Public Google plus profile is very easy. I have seen this question on lots of newbee forums. Google plus have very powerful privacy features than Facebook. Public Google plus profile means people can see your posts even they are not logged into Google plus or They are not in your circles. There is no migration or account change is needed to make your Google profile a public Google plus profile.
So how we can share links with public users?
It is very easy. When you share or post normal posts or website links in your Google plus profile it will ask you which circles should see this post. you can select multiple circles for that. so that post is only visible to people in that circles.
To share it with all people you have to select Public circle when sharing posts. So non Google plus users and people not in your google plus circles also can view that post. Sharing one post in public doesn’t mean that people can see other posts you have shared with your private circles.
Look at image one : How to share posts with public users
Now let’s see how to Show your Plusones / 1+ Tab to other users. When you have shared your one plus tab with other users they can see your 1+ votes.
Go to edit your profile and click +1′s Tab. then check “ Show this tab on your profile “ and click save and done editing. Now your plus ones are visible to public users.
This is how you can share anything on your google plus profile with public users. You can change it again when you share new posts if you want to share it only with few people or few circles.
Go to edit your profile and Click +1′s tab. so you will see this box. Click on show this tab on your profile and save it. now your 1+ tab also visible to public users.
