Ad Network

Definition:
An ad network connects advertisers with websites or apps that want to host ads, offering inventory at scale across a variety of placements.

Why it matters:
Ad networks provide access to wide audiences, but quality can vary significantly, especially when using auto-placement or audience extension options.

Examples:

• Google Display Network

• Meta Audience Network

• Verizon Media, AdRoll, Taboola

Best practices:

• Review performance by domain or app

• Use exclusion lists to remove poor performers

• Don’t rely solely on network defaults for brand safety
