IAS: Video and Display Trackers & Glossary
Trackers for Video:
| IAS Solution | Explanation | Requirements | Measure Viewability | Measure Invisible URLs | Measure Impressions | Measure Brand Safety |
| Multimedia Tag Monitoring (Wrapped Video) | Video tracking tag that will work across desktop, CTV, mobile & in-app. Can measure viewability, set to not block | Requires a VPAID or OMID player/publisher support & 3rd party ad serving | Yes | Yes | Yes | Yes |
| Multimedia Tag Blocking (Wrapped Video) | Video tracking tag that will work across desktop, CTV, mobile & in-app. Can measure viewability, set to block | Requires a VPAID or OMID player/publisher support & 3rd party ad serving | Yes | Yes | Yes | Yes |
| Unified Video 1x1 Pixel | Video tracking tag that will work across desktop, CTV, mobile & in-app. Cannot measure viewability or block | Requires a VAST player & 3rd party ad serving | No | No | Yes | Yes |
Ensuring accurate measurement of viewability and other metrics with IAS requires using Wrapped Video Creative. This is because certain metrics, such as those measured by JavaScript (JS), cannot be captured using the traditional 1x1 pixel. At the same time, the VAST video format also doesn't support a separate JS impression tracker, so Multimedia Tag Monitoring is necessary, wrapping the video within the Creative Tag for accurate measurement. However, in cases where the goal is to measure pure impressions to verify discrepancies, a 1x1 pixel (impression tracker) is sufficient. This tracker, known as "Unified Video Pixel" can be employed for such purposes.
Additionally, It's essential to use VPAID/OMID-compatible video inventory to enable IAS to measure viewability effectively. However, remember that inventory compatible with VPAID/OMID may limit the overall supply available to the campaign.
Trackers for Display:
| IAS Solution | Explanation | Measure Viewability | Measure Invisible URLs | Measure Impressions | Measure Brand Safety |
| Blocking Creative Tag | Display tags with blocking. Requires JS support | Yes | Yes | Yes | Yes |
|
Monitoring JS |
Display tags without blocking. Requires JS support | Yes | Yes | Yes | Yes |
|
Monitoring 1x1 pixel |
Display tags without blocking. | No | No | Yes | Yes |
Viewability measurements are possible with JavaScript tags only. However, some publishers or exchanges might not support this format. In such cases, viewability measurement by IAS wouldn't be possible. Nevertheless, 1x1 monitoring pixels can be utilized for display creatives. By using this type of tracker, IAS would be able to measure impressions to verify the total amount of served impressions.

Glossary:
| Term | Definition |
| Total Tracked Ads |
The number of ads IAS processed. |
| Eligible Ads For Viewability Measurement |
The number of all unblocked ads that are invalid traffic (IVT) free and served in a JavaScript environment where Viewability measurement is possible. |
| Measured Ads |
The total number of ads in the campaign with all detected invalid traffic removed, where IAS was able to collect viewability data. In some ad environments, technical limitations can prevent ads from being measured for viewability or audibility by IAS. |
| Measured Rate (out of Ads) |
The percentage of Measured Ads out of Eligible Ads for Viewability or Audibility Measurement. |
| Viewable Impressions | The number of unblocked viewable impressions in the campaign with all detected invalid traffic removed, where at least 50% of the ad was in view for 1 continuous second for display (2 continuous seconds for video). |
| Viewable Rate (out of measured ads) |
The percentage of Viewable Impressions (at least 1 pixel of the creative rendered on screen; 50% in view for 1 continuous second - display; 2 continuous seconds - video; a 30% or more rule applies to large creatives that are at least 242,500 pixels.) out of unblocked Measured Ads with all detected invalid traffic removed. |
|
Eligible Ads for Invalid Traffic Detection |
Excludes all ads where signals to make an IVT determination are missing. Note: This metric has been updated to no longer include test impressions, which was previously reported as GIVT and represents a trace amount of overall GIVT impressions. Test impressions will still be included in our calculation for Total Tracked Ads. |

The percentage of ads that IAS detected as GIVT, out of all ads processed by IAS. Traffic that failed to meet ad quality criteria filtered through and caught by known IP and bot lists (ex: google web crawlers). |
| Sophisticated Invalid Traffic (SIVT) Ads |
Traffic that failed to meet proprietary and sophisticated invalid traffic detection criteria. Examples of failed traffic can include: hijacked devices, ad tags, or creative; adware; malware; and misappropriated content. |
