I updated my Google+ App on my iPhone and found this..
Google Plus Check-Ins
I have never know google to not use information they collect to better their search results. I foresee Google+ checkins becoming a major part of Google’s Local Search algorithm. The Google+ Check In will add the user data that google is craving to make search results relevant to users. Google places has come a long way. At one time Google scrapped the internet trying to create it’s local directory. They abused Yelp trying to add in reviews. They indexed foursquare to make sure the results were relevant. Now they have their own system to do all this themselves. From reviews to location data, Google+ answers the local directory call.
Can Google+ capture the foodies? As for the foodies, I am not sure, but I do believe Google has the means and drive to eventually beat down Yelp and Foursquare. While Yelp will have a long life and will still hold on to much of it’s elite foodie following, the annoyance and frustration from both businesses and the non-elite users will erode Yelp’s base. But what do I know.. I am just a pest control guy.
