GDN

GDN most commonly refers to the Google Display Network, a vast ecosystem for display advertising owned and operated by Google. It places ads across a large collection of partner websites, apps, and video content that participate in Google's display ads program. The GDN is part of the Google Ads platform and is used by advertisers to reach broad or highly targeted audiences beyond search results.

Advertisers create campaigns using display formats including image ads, responsive display ads, rich media, and video. The network supports targeting by demographics, interests, in-market segments, remarketing, contextual targeting, and topic or placement-based targeting. Advertisers can bid on impressions or conversions, set budgets, and optimize toward goals such as clicks or conversions. Google provides measurement tools such as impressions, clicks, conversions, and view-through metrics, along with reporting on audience segments and placement performance.

Campaigns can be run for awareness, product consideration, or remarketing. The GDN operates through real-time bidding; ads are served based on relevance and expected value to the user and the advertiser's settings. Creative assets are uploaded to Google Ads and then distributed across qualifying sites and apps that display Google ads.

Concerns include ad viewability, brand safety, and the use of cookies for audience matching. Advertisers can exercise control using frequency capping, site exclusions, and placement exclusions.

In other fields, GDN can stand for terms unrelated to online advertising, but in the context of digital marketing it primarily denotes the Google Display Network.
