Featured profiles appear in Max Click Price (or bid) order within the search results, followed by Basic, then Free claimed profiles, then unclaimed profiles (all in distance order).
To always appear in the top spot for your category/market, you must have the top bid. You will set your bids originally on the Bid for Placement page. You will then manage your bids on the My Vendor Listings page.
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.
