Bid landscape
A bid landscape is an estimate of how many impressions a buyer could win, and at what cost, at different bid prices for a given audience or inventory.
A bid landscape is a price-versus-volume curve. It answers questions like "If I bid US$2 CPM, how many impressions will I win? What about US$3 or US$4?" It is built from historical auction data: clearing prices, win rates and, where SSPs share it, minimum bid-to-win information.
DSPs use bid landscapes to power bid shading, forecasting and budget planning, and search platforms offer similar "bid simulators" for keywords. Publishers use a sell-side version to set floors: how much revenue would be lost or gained by raising the floor for a segment.
Landscapes are estimates, not guarantees. Auctions change constantly with seasonality (Q4 prices jump), competitors' budgets, new supply and algorithm changes. Inflated or fraudulent supply can also distort them: a flood of cheap bot inventory makes a low price look like it buys lots of impressions.
Think of it like this
A bid landscape is like a chart showing how many concert tickets you could get at each price on a resale site before you commit.
An example
A DSP forecast shows: US$1.50 CPM wins 2 million impressions a week, US$2.50 wins 5 million, US$4.00 wins 6.5 million. The buyer picks US$2.50 as the best value point.

Win rate
Win rate is the percentage of bids a buyer submits that actually win the auction, calculated as auctions won divided by bids placed, multiplied by 100.
Bid shading
Bid shading is a technique DSPs use in first-price auctions to lower a bid automatically toward the price actually needed to win, so advertisers do not overpay.
Floor price (reserve price)
A floor price is the minimum bid a publisher will accept for an impression; bids below the floor are rejected, even if they are the highest bid in the auction.
Auction dynamics
Auction dynamics are the rules and behaviours that decide who wins programmatic ad auctions and at what price, including auction type, floors, fees, bid shading and bid order.
Pacing
Pacing is how evenly (or deliberately unevenly) a campaign spends its budget or delivers its impressions across its flight dates, so it neither runs out early nor under-delivers.
