Engineering Portal / Digital / Digital Ad Ratings / Digital Measurement SEI Ad Exposure

This document outlines the required specification for facilitating Nielsen ONE advertising measurement, Digital Ad Ratings (DAR) measurement, Ad Effectiveness (MTA, Lift, etc.), and Activation products leveraging the Single Endpoint integration (SEI). Integration specifications for other Nielsen products (DCR, DTVR, etc.) via SEI are available separately.

The Single Endpoint integration contains two components:

  1. Exposure File- the specifications of which are described in this document for the transmission to Nielsen with event level data shared via a Server-to-Server (S2S) method. This S2S file transfer supplies event data and related campaign, study, and user metadata required for facilitating measurement.
  2. Audit Beacon- (implementation details available here: Digital Measurement Ads Audit Beacon) are HTTPS requests that emanate from the end-user device at a minimum of once per Session (uninterrupted user experience with gaps shorter than 30 minutes, or as mutually agreed upon). The Audit Ping provides Nielsen the ability to 1) validate traffic volume 2) provide a signal that Nielsen meters can detect for participating Nielsen panelists.

Ad Measurement Considerations

Nielsen ad campaign setup is required using the Campaign Management Interface (CMI) tool or Tagging API for each campaign where Nielsen reporting is expected - this applies to new or current Nielsen clients transitioning from standard client-device-fired pixel tags to Single Endpoint style.

Nielsen ad pixel tags should not directly fire for any exposures already included in the Exposure File after the testing period. Third-party Nielsen pixel tags should be intercepted, suppressed, and included in a server file transfer with all associated information.

The Audit Ping is required for facilitating MRC Accredited measurement.

S3 Bucket and Prefix Naming Convention

useast1-nlsn-w-dig-sei-<partnerid>-feeds-<env>/<filetype>/<split>/yyyy/mm/dd/hh/<object>

Name Description
partnerid Abbreviation provided by Nielsen for each provider or publisher
env “test” or “prod”
filetype exposure, dcr-exposure, dar-exposure, audio-exposure, etc., where:
  • exposure is reserved for multi-product files
  • <product>-exposure is for single product files, where <product> is [dar|dcr|dtvr|ctvc|audio]
split a separate data split, can be by platform (ex.: ios, browser, android, ctv), by country (us, ca, jp, etc.), by publisher, by team, etc. or “all” (if data is provided in one split).
yyyy/mm/dd/hh
  • yyyy - year
  • mm - month
  • dd - date padded with 0 example 01, 02,..., 31
  • hh - hour padded with 0 example 00, 02,..., 23

S3 Bucket and Prefix Naming Convention

<partnerid>_<filetype>_<intid>_<appid>_<starttime>_<endtime>.[parquet|json]

Name Description
partnerid Abbreviation provided by Nielsen for each provider or publisher
filetype exposure, dcr-exposure, dar-exposure, audio-exposure, etc., where:
  • exposure is reserved for multi-product files
  • <product>-exposure is for single product files, where <product> is [dar|dcr|dtvr|ctvc|audio]
initid integration id: unique identifier provided by Nielsen
appid Nielsen-provided server application identifier
starttime start date and hour of the data in the file in UTC
  • Example format: yyyymmddhh
endtime end date and hour (not inclusive)  of the data in the file in UTC
  • Example format: yyyymmddhh

Success File

Empty _SUCCESS file should be provided to indicate that data delivery for a particular hour and split is completed (even if there is no data for that particular hour and split).

Manifest File

A manifest should be provided which contains metadata related to the uploaded file(s). The manifest is a text file in json format that implements the AWS unload manifest file format. It has the same name as the data file, but has the _manifest suffix.

Example: 

 
{

   "entries": [

     {"url":"s3://bucket/prefix/0000_object_00.snappy.parquet", "mandatory":true},

     {"url":"s3://bucket/prefix/0001_object_00.snappy.parquet", "mandatory":true},

     {"url":"s3://bucket/prefix/0002_object_00.snappy.parquet", "mandatory":true},

     {"url":"s3://bucket/prefix/0003_object_00.snappy.parquet", "mandatory":true}

   ],

   "meta": {

     "schema_version": "S2SV1.7.0",

     "accreditation_status": "0",

     "start_time": "1710154800",

     "end_time": "1710158399",

     "record_count": 55

   }
 }


The manifest contains a complete list of all files provided for a given period and split, as well as a meta data (a.k.a. header) which should include the following attributes:

Parameter Description Require Specified Format / Example Type
schema_version Schema Version Yes Nielsen S2SV1.7.0 String
accreditation_status Accreditation Status No Client MRC = 1 String
data_start_time Data Start Time (min) Yes Client Format:32-bit unsigned int Unix time in seconds String
data_end_time Data Start Time (max) Yes Client Format:32-bit unsigned int Unix time in seconds String
record_count Number of records in data file Yes Client Example: 31337 Number

Data delivery example for hour 11 (11:00:00 AM UTC to 11:59:59 PM UTC):
