When I first transitioned into the world of digital marketing, the sheer number of new terms was initially daunting. I had heard of a cookie before, but what was the difference between a DMP and a DSP? Or a CPI and a CPM?
Adtech — or advertising technology — refers to the technology, software, tools, and platforms advertisers and publishers use to run, monitor, manage, and optimize digital ad campaigns.
Due to the complex nature of digital advertising and the nonlinear evolution of the technology, adtech has developed a dictionary of terms, jargon, buzzwords, and acronyms that can sound like complete gibberish to the uninitiated.
If that’s you, don’t worry — the Grapeseed Media team has put together this glossary of adtech terms as a one-stop-shop resource for beginners and experienced adtech professionals alike.
This A-Z of adtech terminology will help dispel the ambiguity around certain terms and enable you to navigate the adtech ecosystem with confidence and clarity.
Let’s dive in.
The A-Z of Adtech

Ad exchange
A media buying platform that acts as a marketplace where advertisers and publishers can buy and sell ad inventory using real-time bidding.

Ad operations, aka ad ops
A department within a company dedicated to managing ad campaigns. Ad ops specialists typically have a lot of experience working with adtech platforms.
Ad optimization
The process of monitoring and analyzing an ad campaign’s performance and changing it to improve cost-effectiveness.
Ad recall
A metric used in advertising and marketing campaigns to determine the impact of campaign messaging on a brand’s chosen target audience.

Ad targeting
The process of deciding the ideal target audience of an ad campaign using demographic information such as age, gender, location, occupation, marital status, and income level.

Allow list
A list of pre-identified domains that an advertiser authorizes for their ads to be displayed on.

Awareness campaign

Bid response
When a DSP receives a bid request, it runs an auction to determine which ad will be served. The bid response contains information about the winning advertiser and ad creative.
