At this time, you can only see the top (highest) bid in the county. The Current Top Bid can be seen on the Bid for Placement page when you set up your profile originally and on the My Vendor Listings page at any time. You can choose to be notified when you've been outbid on both of these pages as well.
You should set your Max Bid Per Click to be what you are comfortable paying for a click. IMPORTANT: You will only pay $.05 more than the next closest bid to hold your position. If you bid $1.00 per click and the next highest Max Bid Per Click is $.50, you will pay $.55, not $1.00. You will often not be charged the rate you set as your Max Bid Per Click.
