Second model of keyword bidding / auctions
Second model: Google model: Stylized second-price auction
• Pay second, not highest bid.
• But stylized b/c it’s a combo of bid and quality score that determines the rank
• The bidding process by bod price follows an ‘Edgeworth process’
• Each color is a different account; bidders stop when internal economics don’t match, so #2 drops and goes to second position, so 2cnd bidder comes in just above. Same cycle happens over and over again.
• Reverse Bertrand competition
• Bidders change their max bid based on quality and ROI changes, etc.
• Price you would pay is always the bid below you.
• Note: mobile ads can be geofenced (possible to say within x blocks or miles of store for example).

d. Ad Rank = CPC BID x Quality Score
e. Actual CPC = Competitor Rank / Your Qual Score + $0.01
f. * The higher your quality score, the lower your cost per conversion (CPA)
