Attention Metrics Beyond Viewability: What Marketers Need to Know

Viewability tells you an ad had the chance to be seen. It does not tell you whether anyone looked. Research from Lumen, cited by EMARKETER, suggests only around 30% of viewable digital ads are actually looked at ¹. That gap is why attention metrics have moved from a niche research topic to formal industry guidelines and accredited measurement products.

This article explains what attention metrics measure, where the standards now stand, what the evidence says and how to use them without over-claiming.

What attention metrics measure

The IAB and Media Rating Council (MRC) define attention as "the measure of whether the ad was seen or heard by a person and to what depth" ². Viewability, by contrast, only reflects the opportunity to see or hear an ad ².

The guidelines group attention measurement into four approaches ²:

Approach	What it uses	Typical strengths and limits
Data signals	Time in view, audibility, scroll depth, interaction, page and device data	Scales to every impression, but infers rather than observes attention
Visual tracking	Eye and gaze tracking, facial coding, presence detection	Observes looking directly, usually through opt-in panels used to train models
Physiological and neurological	Heart rate, skin conductance, EEG	Measures depth of response, but only in controlled settings
Panels and surveys	Measurement panels, brand studies, ad effectiveness surveys	Links to memory and brand outcomes, but slower and smaller scale

The guidelines also recognise predictive models that connect these approaches ², which is how many commercial products work in practice: observed attention from a panel is used to model attention across all impressions.

The IAB/MRC Attention Measurement Guidelines

The IAB and MRC released the final version 1.0 of their Attention Measurement Guidelines in November 2025, after a public comment period ²³. The key rules for buyers to know:

• Viewability comes first. Viewability is a base requirement, not something attention replaces. Attention metrics that do not meet viewability or audibility requirements must be labelled as diagnostic ².
• Attention is not an outcome. The guidelines state attention "should not be considered or used as a measure of outcomes" for judging campaign performance. It is a data point to read alongside sales, conversions or brand lift ².
• Disclosure. Providers must disclose data sources, signal granularity, modelling techniques and quantifiable error margins, and validate thresholds empirically ².
• Audit. Independent audit is strongly encouraged, and MRC accreditation requires auditing both the inputs and the attention methodology itself ².

Alongside the guidelines, the Coalition for Innovative Media Measurement (CIMM) and IAB published an Attention Measurement Playbook for Marketers in November 2025, based on interviews with nearly 40 industry leaders ⁴.

Vendors and accreditation status

The market includes verification companies that added attention to existing products and specialist attention firms. Accreditation is the clearest way to compare them:

• DoubleVerify received MRC accreditation in April 2026 for its Authentic Attention V4 reporting across desktop, mobile web and mobile in-app, and had accreditation continued for attention metrics based on viewable impressions ⁵.
• Integral Ad Science had started an MRC audit of its Quality Attention product, according to EMARKETER in January 2026 ¹. The MRC's update covering April to June 2026 lists no attention decision for IAS ⁵.
• Adelaide became the first specialist attention firm to enter the MRC accreditation process in October 2024, at the pre-assessment stage, for its AU metric ⁶.
• Lumen provides eye-tracking-based attention models, used in studies such as the Havas Media Network research described below ⁷.

Accreditation status changes, so check the MRC's current list before selecting a vendor.

What the evidence says

The strongest evidence links attention to brand memory and preference, with important caveats.

The largest public dataset comes from Havas Media Network, Lumen and Brand Metrics, which analysed 9,089 display campaigns, 1.88 million survey respondents and 5.6 million viewable impressions, mostly from the UK ⁷. Its findings:

• Longer attention time was associated with higher awareness, consideration, preference and action intent ⁷.
• Single impressions rarely changed brand lift. The strongest results came from several impressions of one second or more, adding up to roughly 2 to 5 seconds of total attention ⁷.
• Frequency drives aggregate attention: ten exposures generated close to 7 seconds in total ⁷.

The study compares results against campaign averages rather than control groups, so it shows correlation, not proof of cause ⁷. Vendor studies of conversion lift exist too, but EMARKETER cautions that attention correlates with outcomes rather than being an outcome itself ¹. The CIMM/IAB playbook makes the same point, describing attention measurement as "probabilistic not deterministic" ⁴.

Adoption is growing. EMARKETER reports IAB data showing 47% of US buy-side decision-makers expected their organisations to focus more on attention metrics in 2025 ¹.

How to use attention metrics in planning

The CIMM/IAB playbook identifies four main use cases ⁴:

1. Inventory assessment. Compare publishers, formats and placements on attention per impression or per pound spent, then use the results in buying and publisher negotiations.
2. Campaign optimisation. Use pre-bid attention segments in programmatic and shift budget in-flight towards placements that score well.
3. Creative testing. Test creative in its media context, before launch and in flight, rather than in isolation.
4. Media mix modelling. Add attention as a quality modifier at channel, publisher or format level.

The playbook also lists pitfalls worth repeating ⁴:

• Using attention as a simple pass/fail filter rather than a graded score.
• Optimising towards a score without understanding what drives it.
• Chasing maximum attention at the expense of reach and cost.
• Treating attention as a standalone metric without linking it to business KPIs.

It recommends starting with a baseline of at least two to four weeks across active media, keeping a holdout or control, and using more than one methodology where resources allow ⁴.

Key takeaways

• Attention measures whether an ad was actually noticed and how deeply; viewability only measures the opportunity to see ².
• The final IAB/MRC Attention Measurement Guidelines (November 2025) keep viewability as the baseline and say attention is not an outcome metric ².
• DoubleVerify holds MRC accreditation for attention metrics; other vendors are at various stages ⁵⁶.
• A study of 9,089 campaigns linked attention to brand lift, with multiple short impressions working better than one ⁷.
• Use attention for inventory selection, optimisation and creative testing, and validate it against your own outcomes ⁴.

What this means for your brand

Attention metrics are most useful as a quality filter on top of viewability, not as a new currency. Start by benchmarking the attention your current media plan delivers, then test shifting budget towards higher-attention placements against a control group, and judge the result on sales or brand lift rather than the attention score. Ask vendors which methodology they use, what validation supports it and where they stand on MRC accreditation, and use the same vendor across channels so comparisons are fair.
