Definition:
RTB, or Real-Time Bidding (Real-Time Auction), is a method of buying and selling online advertising space in real time, through an automated auction process. This system allows advertisers to bid on individual ad impressions at the precise moment a web page is loading for a user.
RTB Functionality:
1. Advertisement Request:
A user accesses a web page with available advertising space.
2. Auction initiated:
– The ad request is sent to a demand-side platform (DSP).
3. Data analysis:
User information and page context are analyzed.
4. Lances:
Advertisers bid based on user relevance for their campaign.
5. Selection of the winner:
The highest bid wins the right to display the advertisement.
6. Ad display:
The winning advertisement is loaded onto the user's page.
This entire process happens in milliseconds while the page is loading.
