Integral Ad Science

Integral Ad Science (IAS) is a digital media measurement and optimization provider serving advertisers, agencies, publishers, and advertising technology platforms. Its solutions measure and verify the quality of digital ad campaigns, covering viewability, brand safety and suitability, invalid traffic (IVT) and ad fraud, and made-for-advertising (MFA) inventory, with data delivered in real time to support campaign optimization.

Coverage spans desktop, mobile, and emerging channels including connected TV (CTV), gaming, and audio, and extends across social media platforms and programmatic environments. For publishers, IAS positions its products as tools to assess inventory quality, remove wasteful impressions, and improve yield. The company also runs a research and threat-detection function: it publishes a recurring Media Quality Report (21st edition available) with regional breakdowns of media quality metrics, and its IAS Threat Lab identifies mobile ad fraud schemes, such as one it named "Papyrus" involving novel-reading applications that generated hidden background browser activity to fake clicks, scrolls, and attention.

Business model

IAS sells verification, measurement, and optimization products to three customer groups — advertisers and agencies, publishers, and platforms/partners — and integrates with media partners and ad technology companies to deliver measurement within their environments.

Traction

Publishes a long-running Media Quality Report now in its 21st edition and cites client work including a Mitsubishi Canada campaign for the 2026 Outlander that used automated media-quality-based targeting.
