Google keeps adding new features to Google+. The company has already taken on Twitter and Facebook with some of the features it has offered. By adding “check-in” features to Google+, Google will aim directly at Foursquare. The ability to check-in via Google+ is nothing new. The documentation available on the site explains how the system will work:
If your customers have to visit your locations in order to do business with you, you can request that they check-in on Google+ in order to redeem your offers. They can choose to share the check-in publicly or with some of their circles, which helps spread the word about your business on Google+. They can also choose to keep their check-in private and still redeem an offer.
If your customers do not have to visit your location, for example if you serve homes or businesses by delivery or by callouts, you can keep this option off (set to “No”) and customers will not be asked to check-in when they redeem offers. We use the Service Areas and Location Settings setting on your listing to determine if you have a service area for offers that have already been created. When you create new offers, you can choose whether to allow a check-in during redemption.
Mike Blumental spotted this on Google when going through the Google Places help files. The feature has not gone live on Google+ yet. But the company clearly has big plans for its location-based services. For those of you wondering, Google has removed the document already. These things won’t last too long once found and covered in the blogging world.
