The Anchor, Sub-Featured, and Featured spotlight placements in the marketplace directory are won by sealed bid each week. Here is the bar to beat right now.
This is for premium directory placement only. In-game video ads are a separate product, sold at a flat rate (see Advertise With Us). Bids here are sealed: no one sees the amount you enter. To help you bid competitively, the current bar to beat is shown below. Winners pay one uniform clearing price, never more than they bid, and the auction settles automatically at the weekly changeover.
