HUMAN’s Ad Viewability Measurement has earned Media Rating Council (MRC) accreditation for display and video impressions across desktop, mobile web, and mobile app environments. The accreditation recognizes a measurement approach we built directly on top of our invalid traffic (IVT) detection infrastructure.
Viewability measurement is harder than it used to be
Viewability measurement exists to answer a simple question: Did an ad have a real chance to be seen? The MRC standard draws a clear line at 50% of pixels in view for at least one continuous second for display, or two seconds for video. The rule is straightforward. Applying it honestly, at scale, in today’s programmatic environment is not.
Traffic patterns have shifted. Automated traffic, including sophisticated bots and now AI agents, accounts for a growing share of activity across the open web. Our 2026 State of AI Traffic report found that automated traffic is growing eight times faster than human traffic year over year, with AI-driven activity up 187%. When a viewability vendor counts impressions without first filtering out invalid traffic, the resulting metric is inflated by impressions that technically met the pixel threshold but were never rendered to a human. Buyers then optimize against a number that overstates real human viewing opportunities, and the downstream decisions are off.
Start with IVT, then measure viewability
IVT-filtered viewability is viewability measurement that filters out invalid traffic before counting viewable impressions, so the metric reflects real human viewing opportunities rather than totals inflated by automated activity.
HUMAN has spent more than 14 years detecting invalid traffic at internet scale. That work gives us a deep, real-time view into what is and is not human across the programmatic supply chain. We built our viewability measurement on top of that foundation rather than alongside it.
Before we count a viewable impression, we filter out the invalid traffic that should not have been counted in the first place. What remains is a viewability metric that reflects genuine human opportunity rather than a raw count padded by bot activity that happened to meet the geometric standard.
In practice, this shows up as three things:
What the accreditation confirms
MRC accreditation is a rigorous, audited review of methodology against industry standards. For customers, it is third-party validation that the measurement under the hood does what it claims to do.
This is HUMAN’s latest accreditation, not our first. Our Sophisticated Invalid Traffic detection and pre-bid IVT detection are already MRC-accredited, as are our tracked ads and rendered ad impressions measurement. The newly accredited viewability measurement is delivered through FraudSensor, HUMAN’s post-bid ad fraud and verification platform, which means the IVT filtering underneath our viewability metric is held to the same audit standard as the metric itself.
Sovrn, a technology platform serving publishers, creators, and advertisers, uses our viewability reporting to support decisions across its business. Jeff Meglio, Managing Director of Sovrn, put it this way:
“Our long-standing partnership with HUMAN reflects a shared commitment to transparency and precision across the media ecosystem. HUMAN’s viewability metrics provide confidence in performance measurement with detailed reporting that supports day-to-day operational decisions.”
What this means for buyers and sellers
For advertisers and agencies, IVT-filtered viewability produces a cleaner baseline for optimizing spend. If you know which supply paths produce viewable impressions against real human traffic, and which produce inflated numbers, you can reallocate the budget accordingly.
For publishers and SSPs, accredited, transparent measurement is a prerequisite for the trust that keeps advertiser budgets flowing. Honest measurement protects premium inventory from being lumped in with low-quality supply and gives sellers a shared frame of reference with buyers.
For platforms and retail media networks, consistent, defensible measurement across environments supports credibility with both sides of the market.
Where viewability fits in HUMAN's verification practice
Viewability is one dimension of a larger verification problem that also includes invalid traffic and brand safety. HUMAN’s approach to each starts in the same place: filter out automation and fraud first, then measure what remains. That discipline is now MRC-audited for viewability as well.
