Real-Time Bidding (RTB) is a method of buying and selling online ad impressions through real-time auctions that occur in the time it takes a webpage to load. These auctions are often facilitated by ad exchanges or supply-side platforms (SSPs). RTB allows advertisers to bid on individual impressions, ensuring that their ads are shown to the most relevant audience at the optimal price.

1. Impression: A single instance of an ad being displayed to a user.
2. Bid Request: A request sent from the publisher's ad server to the ad exchange, containing information about the user and the context of the ad placement.
3. Bid Response: The response from the advertiser's demand-side platform (DSP) with the bid amount and the ad creative.
4. Auction: The process where multiple advertisers bid for the same impression, and the highest bid wins.
5. Ad Exchange: A digital marketplace that facilitates the buying and selling of ad inventory from multiple ad networks.

1. User Visits a Website: When a user visits a website, the publisher's ad server sends a bid request to the ad exchange.
2. Bid Request Sent: The bid request includes information such as user demographics, browsing history, and the context of the webpage.
3. Advertisers Bid: Advertisers, through their DSPs, analyze the bid request and decide how much to bid for the impression.
4. Auction Held: The ad exchange conducts an auction among the bids received.
5. Winning Bid: The highest bid wins the auction, and the ad is served to the user.
6. Ad Displayed: The winning ad is displayed on the publisher's website as the page loads.

• Efficiency: Automates the ad buying process, reducing the need for manual negotiations.
• Targeting: Allows precise targeting based on user data and context.
• Cost-Effectiveness: Advertisers only pay for impressions that are valuable to them.
• Transparency: Provides detailed insights into where and how ads are being displayed.

• Complexity: Requires sophisticated technology and expertise to manage effectively.
• Fraud Risk: Susceptible to ad fraud, such as fake impressions and clicks.
• Privacy Concerns: Involves extensive data collection, raising privacy issues.
