Ad Auction Live
Every Google ad you see has just won an auction. Four teams run four shops bidding for the top ad on "trainers sale". The biggest wallet rarely wins.
- Why quality can beat a bigger budget
- How a second-price auction sets what you pay
- Why the top ad is not always the most profitable
- How AI Overviews change what a click is worth
How to run it in your class
- Open the game on the classroom screen. Split the room into four teams, one shop each.
- Start the timer. Each team agrees one secret bid per click and writes it down.
- Type the bids in and press Bang the gavel to reveal Ad Rank, positions, prices and profit.
- Play three rounds: trainers sale, fix the landing page, then an AI Overview halves the clicks. Finish with the podium and debrief.
