What is Real-Time Bidding (RTB)?

Real-time bidding (RTB) is a subset of programmatic advertising that automates the buying and selling of digital ad impressions through instant auctions. When a user visits a website or app, RTB facilitates a competitive bidding process where advertisers vie for the opportunity to display their ads. The process takes place in milliseconds before the webpage or app fully loads.

How Does Real-Time Bidding Work?

Real-time bidding operates through a streamlined process involving key platforms:

1. Supply-Side Platforms (SSPs): These platforms connect publishers to ad exchanges and enable them to sell ad inventory to advertisers.

2. Demand-Side Platforms (DSPs): Advertisers use DSPs to evaluate inventory and submit bids based on their audience targeting strategies.

3. Ad Exchanges: The marketplace where SSPs and DSPs interact, hosting real-time auctions.

The RTB Process

• A user accesses a website or app.

• The SSP sends a bid request to the ad exchange, including data like the user’s location, browsing history, and device type.

• DSPs evaluate the request and submit bids, factoring in their campaign goals and budget.

• The highest bid wins, and the ad is instantly displayed to the user.

RTB eliminates the need for manual negotiations and insertion orders, making ad buying faster, more efficient, and highly targeted. For advertisers, it ensures that impressions are served to the most relevant audiences, reducing wasted ad spend. For publishers, RTB increases competition for ad space, driving higher revenue.

By leveraging programmatic advertising real-time bidding, businesses can optimize their digital campaigns, adjust budgets in real-time, and gain better control over their advertising outcomes.
