The Media Rating Council (MRC) has determined that some metrics related to measurement meet the industry standard for accreditation. Learn more about the Campaign Manager 360 methodology and Display & Video 360 methodology for accreditation.

Which metrics are accredited?

If a metric is accredited by the MRC, the metric definition and tooltip will include the note “Accredited by the Media Rating Council” and the MRC logo. If you download a report from report builder as a CSV file, accredited metrics are listed in the row “MRC Accredited Metrics”. A metric without a note means that the MRC does not accredit it.

Accredited environments and format types

Not all environments and format types for a metric are MRC accredited. Accredited metrics apply to the following environments and format types:

• Desktop display
• Desktop video
• Mobile app displaya
• Mobile app video
• Mobile web display
• Mobile web video
• (Some metrics) Connected TV (CTV) video

For Display & Video 360 YouTube & partners line items, accredited metrics apply to all in-stream ads, except those on the Google TV inventory source and those served on YouTube TV. Non-in-stream ads, including metrics for YouTube Shorts ads, are not currently accredited. YouTube inventory is not accredited for Campaign Manager 360, so use Display & Video 360 Report Builder to access accredited metrics for YouTube & partners line item ads. Inventory bought through Display & Video 360 Demand Gen line items are not accredited.

Calculate accredited metrics

Accredited clicks and click rate

For clicks and viewability based metrics, sophisticated invalid traffic (SIVT) filtration and methods other than "Begin to render" are not accredited by the MRC.

Gross clicks

Gross Clicks includes all recorded clicks, including invalid and valid clicks. Gross clicks is not a metric in the Report Builder, but you can use the following formula to calculate it:

Calculation	Formula
Gross clicks	Clicks + Invalid Clicks

Accredited impressions

MRC accredits some Begin to Render impressions and Active View impressions. Note that mobile app Begin to Render Impressions and Tracked Ads are not MRC accredited for SIVT filtration for Campaign Manager 360 and Display & Video 360.

Gross impressions

Gross impressions includes both valid and invalid occurrences. The Report Builder does not have these metrics, but you can use these formulas to calculate them:

Calculation	Formula
Gross Begin to Render impressions	Begin to Render Impressions + Invalid Begin to Render Impressions
Gross Active View viewable impressions	Active View: Viewable Impressions + Invalid Active View Viewable Impressions
Gross Active View measurable impressions	Active View: Measurable Impressions + Invalid Active View Measurable Impressions
Gross Active View eligible impressions	Active View: Eligible Impressions + Invalid Active View Eligible Impressions
Gross Begin to Render impressions (excluding Inactivity)	Begin to Render Impressions + Invalid Begin to Render Impressions - Inactive Impressions

Total net impressions

The total net impressions include only the valid Begin to Render and Active View impressions. This means that the impressions have been filtered for traffic quality. In the Report Builder, the following metrics measure valid impressions:

• Begin to Render Impressions
• Active View: Viewable Impressions
• Active View: Measurable Impressions
• Active View: Eligible Impressions

Net of general invalid traffic (GIVT) impressions

Net of GIVT impressions includes the impressions after filtering out GIVT impressions. This calculation still includes SIVT as part of the total. The Report Builder does not have these metrics, but you can use the following formulas to calculate them:

Calculation	Formula
Begin to Render Impressions (Net of GIVT)	Begin to Render Impressions + Invalid Begin to Render Impressions - General Invalid Traffic (GIVT) Begin to Render Impressions
Active View Viewable impressions (Net of GIVT)	Active View: Viewable Impressions + Invalid Active View Viewable Impressions - General Invalid Traffic (GIVT) Active View Viewable Impressions
Active View Non-viewable impressions (Net of GIVT)	[Active View: Measurable Impressions + Invalid Active View Measurable Impressions - General Invalid Traffic (GIVT) Active View Measurable Impressions] - [Active View: Viewable Impressions + Invalid Active View Viewable Impressions - General Invalid Traffic (GIVT) Active View Viewable Impressions]
Active View Measurable impressions (Net of GIVT)	Active View: Measurable Impressions + Invalid Active View Measurable Impressions - General Invalid Traffic (GIVT) Active View Measurable Impressions
Active View Unmeasurable impressions (Net of GIVT)	[Active View: Eligible Impressions + Invalid Active View Eligible Impressions - General Invalid Traffic (GIVT) Active View Eligible Impressions] - [Active View: Measurable Impressions + Invalid Active View Measurable Impressions - General Invalid Traffic (GIVT) Active View Measurable Impressions]
Active View: % Measurable impressions (Net of GIVT)	[Active View: Measurable Impressions + Invalid Active View Measurable Impressions - General Invalid Traffic (GIVT) Active View Measurable Impressions] / [Active View: Eligible Impressions + Invalid Active View Eligible Impressions - General Invalid Traffic (GIVT) Active View Eligible Impressions]
Active View: % Viewable (Net of GIVT)	[Active View: Viewable Impressions + Invalid Active View Viewable Impressions - General Invalid Traffic (GIVT) Active View Viewable Impressions] / [Active View: Measurable Impressions + Invalid Active View Measurable Impressions - General Invalid Traffic (GIVT) Active View Measurable Impressions]
