Programmatic Advertising Glossary
Programmatic advertising can be difficult to understand if you’re unfamiliar with the process. To help make sense of it, we have provided a list of key terms and actors in the programmatic digital media supply chain.
Ad Exchange – the space in the Programmatic Advertising system where brands/agencies and publishers buy and sell inventory
Buyer – brands and agencies who purchase inventory (ad space) from publishers
Cost Per Thousand (CPM) – the value of an impression proposed by buyers and set by publishers; the highest CPM bid by the buyer wins the impression
Click-Through Rate (CTR) – a measurement for marketers to determine how many times a link was clicked
Data Management Platform (DMP) – platforms used by marketers to collect, organize, and utilize data to market to their target audience in programmatic advertising campaigns
Data Suppliers (also known as Data Providers) – provide brands and agencies with third-party data to use alongside their first-party data
Demand-Side Platform (DSP) – a place for buyers to store creatives or ads and learn about available inventory from publishers
Deterministic Data – data that consists of unique identifiers (like usernames, email addresses, and phone numbers) that determine who individuals are; often provided by consumers themselves
First-Party Data – data that a brand has collected from its owned properties – like on their website or at point of sale
Inventory – also known as ad space or impressions, which publishers sell to buyers
Private Marketplace (PMP) – a variation of RTB (Real-Time Bidding) where only a select number of advertisers bid for ad space
Probabilistic Data – data that is used to segment consumers based on their characteristics and behaviors online
Programmatic Advertising – an automated system designed for marketers and publishers to buy and sell ad space
Programmatic Direct – a process in which inventory is not being auctioned off by publishers. There is only one buyer purchasing inventory at a fixed, negotiated CPM
Public (Open) Auction – utilized by publishers in the RTB process to make their inventory available to all buyers in the Ad Exchange
Publisher – sells ad space to brands and agencies through SSPs (Supply Side Platform) to monetize their websites; determines CPM of ad space
Real-Time Bidding (RTB) – the process in which digital advertising is bought and sold via auction instantaneously
Supply-Side Platform (SSP) – where publishers sell their inventory
Third-Party Data – audience information that is provided by Data Suppliers to brands and agencies to augment their first-party data and expand reach; Tip: Many data suppliers lack high-quality data. Make sure yours can provide data that is multi-sourced and validated.
