Integral Ad Science
Integral Ad Science is an independent media measurement and optimization company focused on advertising quality. Its technology measures and helps optimize viewability, invalid traffic, brand safety and suitability, contextual relevance, and attention across open-web, social, mobile, video, gaming, audio, and connected television environments, with integrations available before bidding and after delivery. It is intended for brands, agencies, publishers, and platforms that need external verification while aligning campaign placement rules with their own risk tolerance and media objectives.
What it does
Integral Ad Science (IAS) is an independent verification vendor that scores the quality of digital media so advertisers know their ads ran in viewable, fraud-free, brand-safe environments. It measures viewability, invalid traffic, brand safety and suitability, contextual relevance, and increasingly attention across open web, social, CTV, video, audio, and in-game inventory. Pre-bid segments let buyers avoid risky impressions before they purchase, while post-bid measurement reports on what actually delivered. Because IAS is third-party rather than the platform selling the media, its numbers act as a neutral check; advertisers still set their own suitability tiers and risk thresholds, since one brand's acceptable context is another's no-go.
Where it fits
IAS plugs into the analytics and optimization layer of programmatic buying, validating that DSP-purchased impressions meet quality standards before and after delivery.

Beginner notes
- Decide your suitability tier deliberately — over-blocking shrinks reach and inflates CPMs without always reducing real risk.
- Compare IAS viewability with the platform's own numbers; gaps are normal because measurement methods differ.
- Pre-bid avoidance is cheaper than post-bid regret, so configure exclusion segments before scaling spend.
