Key takeaways
- Viewability shows an ad could be seen. Attention shows it was noticed and processed.
- Click-through rate alone can be gamed and misses upper-funnel impact.
- Video delivers the strongest attention, while static suits cost-effective retargeting.
- Test one variable at a time and wait for statistical significance.
- Report by creative, not just by channel.
What is the difference between viewability and attention?
Viewability tells you whether an ad had the chance to be seen. Attention tells you whether it was noticed and processed. Viewability is a technical check that the ad appeared on screen, while attention measures how long people focused on it and how they interacted.
This matters because media delivery alone does not drive response. Creative quality and relevance decide whether reach turns into action, so tracking creative performance supports smarter optimisation and better return on investment.
Which creative metrics should you track?
| Metric | What it measures |
|---|---|
| Viewability | At least 50% of the ad in view for a minimum time, 1 to 2 seconds |
| Attention rate | Time in view, interaction and scroll velocity combined |
| View-through rate (VTR) | Percentage of video completions at 15 seconds, 30 seconds and so on |
| Engagement | Clicks, hovers, swipes and taps |
| Interaction rate | Percentage of users who engage with a rich media asset |
| Brand lift | Change in awareness, perception or recall against a control group |
| Completion rate | Percentage who view the whole ad unit |
| Cost per attention second | Media cost divided by total seconds of attention, an emerging metric |
Analyse these together rather than in isolation.
What are the viewability standards?
The Media Rating Council (MRC) sets the industry standard:
- Display: 50% in view for one second.
- Video: 50% in view for two seconds.
- Large format (970x250 and above): 30% in view for one second.
- Audio: audible for two seconds.
GroupM applies a higher standard: 100% in view for one second for display, and 100% in view with audio for 50% of the duration for video.
Third-party tools verify viewability, including DoubleVerify, MOAT, Integral Ad Science, Comscore and Nielsen Digital Ad Ratings. The limits are important. Viewability does not mean the person paid attention, platforms measure differently, and it ignores ad quality and relevance.
How do you measure attention?
Attention metrics add the behavioural detail that viewability lacks.
- Time in view: how long the creative was visible. Longer times typically relate to better recall.
- Scroll velocity: whether the person scrolled past quickly or stopped to read. Slower scrolling signals more interest.
- Exposure sequencing: whether repeated exposures across placements built recall.
Specialist tools include Adelaide, Amplified Intelligence and the DoubleVerify Attention Index. Amplified Intelligence uses eye tracking to measure actual visual attention.
Indicative average attention times are 0.5 to 1.2 seconds for static banners, 2 to 4 seconds for skippable video, 1.5 to 2.5 seconds for in-feed native and 1.5 to 2.2 seconds for digital out-of-home (DOOH). Creative quality can move these by up to 40% in either direction.
Which creative formats deliver the most attention?
| Format | Viewability | Attention | Best use |
|---|---|---|---|
| Static | Medium | Low to medium | Retargeting, mid-funnel |
| Video | High | High | Awareness, product explainers |
| HTML5 | High | Medium | Rich media, interaction |
| Native | High | Medium | Story-driven content |
| DOOH | Not trackable | Implied | Mass awareness |
Video consistently earns the highest attention but costs more to produce. Static stays cost-effective for retargeting.
Match format to the goal and the audience's behaviour. Video suits awareness and explainers, HTML5 and native balance engagement with broader reach, and DOOH offers mass exposure but with less precise measurement.
Format is only one factor. Creative quality (branding, hook and call to action), placement (above or below the fold), device (mobile users give shorter bursts of attention than desktop) and frequency all matter. The guide suggests 3 to 7 exposures as the optimal range for most campaigns, with diminishing returns beyond that.
Why is click-through rate not enough?
CTR has three weaknesses. Clickbait can inflate it without driving real engagement or conversions. It misses upper-funnel effects such as awareness and perception shifts that happen without a click. And it is shaped by format, placement, audience, creative and competition, so isolating the cause is hard.
Attention and engagement also play different roles. Attention is passive but measurable and is a prerequisite for deeper engagement. Engagement, such as clicks, shares and comments, has historically been overvalued as the main success measure. Attention often predicts brand recall and consideration lift better than CTR does, so the strongest campaigns optimise for both.
How do you test creative properly?
- Run A/B tests and change only one variable at a time.
- Segment results by audience, placement and device.
- Check significance: look for p-values below 0.05 and sample sizes large enough to trust.
- Include attention metrics such as time spent, scroll depth and engagement actions.
Keep a regular testing calendar and store results in a central creative insights library so teams do not repeat failed ideas.
Then apply what you learn. Adjust video length using drop-off points, with 15 to 30 seconds suiting awareness and 6 to 15 seconds suiting conversion. Refresh static ads that show attention decay after 3 to 5 days. Sequence messages from awareness to consideration to conversion, and personalise high-attention formats with first-party data.
How should you report and read the results?
Set up reporting so creative is visible, not buried in channel totals.
- Report by creative, not only by channel.
- Break out performance by device, format and size.
- Tag every asset with UTM or DSP tracking and a consistent naming convention.
- Include attention or engagement heatmaps where available.
For brand safety, wrap creative in verification tags from DoubleVerify, IAS or MOAT before launch, set thresholds such as 70% minimum viewability, and block invalid traffic and unsafe placements.
Platform-specific signals help too: Meta responds to a hook in the first three seconds, YouTube to early branding and captions, and TikTok to a native feel with sound on.
Read results holistically. Blend quantitative data with qualitative insight, use time in view as a proxy for upper-funnel impact when brand metrics are unavailable, avoid decisions based on one metric, and favour multi-week trends over one-week snapshots. Common pitfalls include over-indexing on CTR, lumping creative into channel metrics, leaving creative live too long and using identical assets on every platform.
Frequently asked questions
Does high viewability mean people paid attention?
No. Viewability only confirms the ad could have been seen. Attention metrics such as time in view and scroll velocity show whether it was actually noticed.
Which tools measure attention?
Adelaide, Amplified Intelligence and the DoubleVerify Attention Index are specialist options. Looker Studio can combine their data with other metrics in one dashboard.
How often should static ads be refreshed?
Static ads that show attention decay after 3 to 5 days of running should be refreshed. Monitor fatigue patterns and rotate regularly.
