Other Local Business Ads
You will see ads of other local businesses in the left column of your listing page. These are your connections! Your ads are rotating on their pages too. It is a way to get your listing seen by MORE potential customers.
Of course if you are connected with a competitor, you might want to disconnect from them to keep their local network ads off your page. Visit Your Connections and use the search box to quickly find them. Click the red X to remove them.
