Active View metrics are calculated by finding the percentage of total impressions served that are actually viewable impressions:
- From the total impressions served, a certain percentage are eligible impressions.
- From those eligible impressions, a certain percentage are measurable impressions.
- From those measurable impressions, a certain percentage are viewable impressions.

Example
Measurable %
From the 1,000,000 total impressions served, 900,000 of those impressions are eligible for Active View.
From the 900,000 eligible impressions, only 800,000 are measurable. The following formula is used to calculate measurable %:
- Measurable impressions (800,000) / Eligible impressions (900,000) = 88.88%
This means that almost 89% of your eligible impressions are measurable by Active View.
Viewable %
Of these 800,000 measurable impressions, only 350,000 are viewable. The following formula is used to calculate viewable %:
- Viewable impressions (350,000) / Measurable impressions (800,000) = 43.75%
This means that almost 44% of your measurable impressions are viewable—the impressions appeared within a user’s browser and had the opportunity to be seen.
