A profile on Google+ is quite similar to a personal profile on Facebook or LinkedIn. It helps you share your opinions, take part in discussions and connect with like-minded individuals and communities on the network. Although it has not really caught on as a social network, Google indexes your Google+ posts in the search results if you’ve enabled the setting to be discoverable on Google. Since each post has a unique URL, when someone engages with your content, there’s a good chance that it could surface as a ranked search result. 

A page on Google+ is usually managed under a brand account by the team members of an organisation. Let’s say it’s similar to a Facebook Page or a LinkedIn Company Page. It helps your team publish posts and engage with your audience. 

A business listing on Google is managed from Google My Business that incorporates Google Search, Maps and Google+. It refers to the actual store or business in a physical location. You can display your business information such as address of your store, business hours, contact number, travel directions, ratings and reviews with pictures from customers etc. on Google Maps as well as on the Knowledge Panel. Zoho Social helps you schedule Google Posts with an optional button for adding your landing page URL. You can also track and respond to reviews for your business listing from the Monitor tab.
