Key ideas in Digital Media Trading
- A user visiting a page triggers an ad request before content finishes loading
- Ad platforms automatically submit bids for matching marketing campaigns in milliseconds
- The highest bid wins and its ad displays immediately on the user's screen
- In a first-price auction, the winner pays their full submitted bid amount
- Modern ad exchanges no longer discount winning bids down to one cent above second place
- Marketers overpay if they bid higher than necessary under first-price rules
- Bid shading looks at past auction prices to find the lowest bid likely to win
- It protects marketing budgets from paying full maximum bids on every single impression
- It automates bid discounting that used to happen naturally in older auction formats
- Sequence of events that serves a targeted ad when a user opens a webpage
- A bid cap establishes a strict ceiling on the most your campaign will spend for any single ad placement
- Without caps, automated bidding can chase expensive spikes and drain budgets rapidly
- Setting limits lets marketers control spend efficiency even when auction competition jumps
- CPM prices the baseline volume of eye-level views (impressions) in blocks of 1,000
- CPM charges for media visibility whether or not anyone clicks the ad
- More downstream metrics like clicks or purchases build on top of baseline impression costs
