Attention metrics are measurements that try to establish whether a person actually looked at, listened to or engaged with an advertisement, and to what depth, rather than whether it simply had the opportunity to be seen. They exist because the industry's baseline quality standard, viewability, describes a condition of the ad and not a behaviour of the audience. A display ad counts as viewable when half its pixels sit on screen for one continuous second. Nobody has to look at it.

The category spans eye-tracking panels, brainwave studies and machine learning scores computed for every impression in an auction. The unit of interest is the person, not the device. The Media Rating Council (MRC), the US body that accredits media measurement, formalised that point in 2025 guidelines written with the Interactive Advertising Bureau (IAB).

How attention is measured

The IAB/MRC Attention Measurement Guidelines, released as a draft for public comment on May 12, 2025, sort the field into four methods. Data signals come from devices, ad servers and publisher metadata: time in view, scroll depth, share of screen, ad density, audibility and interactions. Visual tracking covers eye tracking, gaze tracking and facial coding, usually among consenting panellists. Physiological and neurological observation records heart rate variability, skin conductance and brain activity through electroencephalography (EEG). Panel and survey methods ask people what they remember. A fifth category, predictive models, joins them: according to the draft, such models aim to predict the value of a visual tracking outcome using only the data signals available from standard logging.

That fifth category dominates programmatic trading. Lumen Research, a UK company, trains its models on eye-tracking data from consented participants and then scores impressions without a live panel, as PPC Land described when Teads extended Lumen measurement to connected television (CTV) home screens in May 2026. Adelaide's Attention Unit (AU), a 0-to-100 score, predicts a placement's likelihood of capturing attention from signals including ad size, time in view, clutter and position.

The draft splits measurement into three dimensions - content, placement and creative. Its minimum requirements are demanding. Attention must accrue on top of MRC-compliant viewable impressions, filtered for sophisticated invalid traffic (SIVT), with reasonable assurance that a human was present. Attention recorded before an ad turns viewable may be reported, but separately and labelled diagnostic. Models must be revalidated against fresh deterministic data at least once a year.

Vendors compress dozens of inputs into one figure. DoubleVerify's Authentic Attention combines exposure and engagement indices from more than 50 data points against a global benchmark of 100; its first global attention benchmark report, in December 2023, put media and sports advertisers at 117 and telecoms at 75. Other vendors report volumes. InMobi's Attention Per Mille (APM) multiplies the share of impressions viewed by average view time and normalises to 1,000 impressions. A campaign in which 60% of impressions are viewed for an average of five seconds yields 3,000 APM. Bought at a 10 euro cost per thousand impressions (CPM), that is roughly 3.3 euros per thousand attentive seconds, a unit that lets a cheap banner and an expensive CTV spot be compared directly.

Where the score enters the transaction

Attention data touches a campaign at three points. Before buying, planners use placement benchmarks to shortlist inventory. During buying, scores act as filters or bid inputs inside a demand-side platform (DSP). Adelaide's Amazon DSP segments, launched on June 10, 2026, tier inventory into high, average and low bands, and a Quality Floor removes made-for-advertising sites and the bottom 10% of AU-scored placements in one step. In Display & Video 360 (DV360), Google made AU a Custom Bidding signal from mid-July 2026: an advertiser's scoring function assigns each impression a value, and the bid is priced against it. Afterwards, verification tags report delivered attention.

The mechanics favour prediction. A panel observes a sample, so a panel-derived score cannot be attached to every bid request, whereas a model can. Predictive scores therefore reached bidding systems first.

Sellers use the same data to package attention-guaranteed deals. At an IAB Europe panel on July 3, 2025, Lauren Dick of Mail Metro Media said attention runs more than 10% higher in news inventory, an argument aimed at buyers who avoid news.

Origin and evolution

Time as a trading signal predates the label. On September 29, 2014, the MRC accredited 21 metrics from Chartbeat, a publisher analytics firm, including Active Exposure Time. According to Chartbeat's methodology, an ad earns a second of credit only when it is viewable and the reader is scrolling or typing. The MRC had finalised its viewable impression guidelines three months earlier, on June 30, 2014.

The Financial Times built a pricing model on that data. According to the FT's announcement, a pilot with 10 advertisers including BP, iShares and IBM generated more than $1 million in incremental revenue before cost per hour (CPH) pricing launched on May 18, 2015. Advertisers paid only for ads seen for more than five seconds of active time at 100% viewability. The Economist followed in November 2015.

A second wave turned attention into verification products. DoubleVerify secured MRC accreditation for Authentic Attention on January 4, 2023, covering display and video across desktop, mobile web and mobile app. Integral Ad Science (IAS) launched Quality Attention with Lumen in January 2024. DoubleVerify took its product to Snapchat on June 30, 2025.

Standardisation came last. The IAB Attention Task Force, with more than 200 members, drafted the guidelines, and comments closed on July 12, 2025. Angelina Eng, the IAB's vice-president of measurement, said that without a shared standard the market had "become a bit of a Wild West situation", according to the IAB announcement. The guidelines were finalised on November 12, 2025, opening the way for accreditation audits against a common framework.

Why it matters for marketers

TVision reported on August 25, 2026 that of more than 200 minutes of daily video viewing, 24 are advertising opportunities and nine are attentive advertising time. The company, now owned by the DSP Viant, runs a panel of 5,000 US households fitted with sensors. Such numbers move attention into the buying brief.

Adoption has followed. Lucy Wallace, head of programmatic at Publicis Next, told the IAB Europe panel that attention had become "easier than ever to test". EssenceMediacom France reported that attention-based custom bidding in DV360during July 2024 delivered CPMs 7.3% more cost-effective than standard automated bidding. Measurement firms have fused attention with currencies: Nielsen combined AU with its reach data on October 7, 2025, and Uber Advertising trained a platform-specific AU model on Kantar brand lift results.

Limitations and disputes

Comparability is the central problem. Vendors compute attention through proprietary methods, and a score of 60 in one system does not equal 60 in another. DoubleVerify reports an index, Adelaide a placement score, InMobi a volume in seconds. Anya Libova of DoubleVerify told the IAB Europe session that one model she used drew on more than 50 metrics, obscuring what an optimisation actually chases. The guidelines standardise vocabulary and disclosure, not method.

The link to outcomes is contested. The draft states plainly that attention in and of itself should not be used as a measure of campaign outcomes. A Kantar analysis of 873 campaigns and $3.2 billion in media spend, published in July 2024, found that overall channel attention levels did not directly correlate with brand contribution or cost-effectiveness. Cara Pratt of Kroger Precision Marketing told The Current in October 2024 that the retailer was "not even seeing a sales correlation to high attention metrics", though she said the same of viewability. Vendors cite their own evidence: IAS has claimed up to a 130% lift in conversion rates for high-attention impressions, a vendor-supplied figure.

Audit coverage is uneven. DoubleVerify holds MRC accreditation for its attention metrics, while IAS has announced no equivalent accreditation for Quality Attention. Predictive models inherit the blind spots of their training panels. Optimising for attention can also reward large, intrusive formats that hold the eye at the expense of user experience, a risk the draft itself flags. Privacy law narrows the field: gaze and facial data need explicit consent under the General Data Protection Regulation (GDPR), confining direct observation to panels.

Not the same as

Viewability records whether an ad met a pixel and time threshold. Attention asks whether a person looked. The two can diverge in either direction, and the MRC treats viewability as a precondition for accredited attention measurement.

Engagement metrics such as click-through rate and video completion record actions. Attention models use them as inputs, yet a click can end attention by taking the user elsewhere, a case the draft asks vendors to handle.

Brand lift and sales measurement are outcomes. Attention sits upstream of them as a signal about exposure quality.

Quality Attention, AU and Authentic Attention are proprietary products inside the category, not synonyms for it.

Recent developments

Over the summer of 2026 attention moved into the auction. After the Amazon DSP and DV360 integrations, InMobi launched FRAME Attention on July 24, 2026 with an 8,000 APM floor across in-app video and CTV, equivalent to eight attentive seconds per impression on average.

Adelaide has also put a self-service Media Quality Calculator online that grades advertiser site lists against AU. Co-founder Zach Kubin promoted it in late August 2026 alongside a company claim that more than $27 billion a year flows into lower-quality programmatic inventory. Only a model, not a panel, can grade thousands of domains on request. The same list may score differently against IAS, DoubleVerify or Lumen, which leaves the oldest question in the category, whose number to trust, unresolved as of September 2026.

Summary

Who. Measurement vendors including DoubleVerify, IAS, Adelaide, Lumen Research and TVision produce attention metrics; DSPs including Amazon DSP and DV360 activate them; publishers and SSPs package inventory around them; the MRC and IAB set the guidelines and the MRC accredits.

What. Attention metrics estimate whether a person looked at or listened to an ad and to what depth, using data signals, visual tracking, physiological observation, panels and predictive models, and report the result as indices, scores or attentive seconds.

When. Time-based precursors were accredited in September 2014 and traded by the Financial Times from May 2015. Vendor products gained accreditation from January 2023, industry guidelines were finalised on November 12, 2025, and scores entered DSP bidding in June and July 2026.

Where. Across display, video, social, CTV, audio and out-of-home, in planning tools, pre-bid segments, bidding algorithms and post-campaign reports.

Why. Viewability confirms only that an ad could be seen. Attention metrics try to price whether it was, though vendor scores are not comparable and their link to sales remains disputed.
