DCR Static Browser Bundled SDK

Engineering Portal / Digital / DCR & DTVR / DCR Static Browser Bundled SDK

Prerequisites

To get started, an App ID is needed. The App ID is a unique ID assigned to the player/site/app. This will be provided upon starting the integration.

'PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'

Implementation Steps

Add Tracking Code

The Nielsen DCR Tracking Code must be added to each page.

<script>
  // Static Queue Snippet
  !function(t,n){t[n]=t[n]||{nlsQ:function(e,o,c,r,s,i){return s=t.document,r=s.createElement("script"),r.async=1,r.src=("http:"===t.location.protocol?"http:":"https:")+"//cdn-gl.imrworldwide.com/conf/"+e+".js#name="+o+"&ns="+n,i=s.getElementsByTagName("script")[0],i.parentNode.insertBefore(r,i),t[o]=t[o]||{g:c,ggPM:function(n,e,c,r,s){(t[o].q=t[o].q||[]).push([n,e,c,r,s])}},t[o]}}} (window,"NOLBUNDLE");

  // SDK Initialization
  var nSdkInstance = NOLBUNDLE.nlsQ("PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX","nlsnInstance", {nol_sdkDebug: "debug"});
  
  // Content Metadata 
  var nielsenMetadata = {
    type: 'static', 
    assetid: '', // *DYNAMIC METADATA*: unique ID for each article **REQUIRED**
    section: '', // *DYNAMIC METADATA*: section of site **REQUIRED**
    segA: '', // *DYNAMIC METADATA*: custom segment
    segB: '', // *DYNAMIC METADATA*: custom segment
    segC: ''  // *DYNAMIC METADATA*: custom segment
    }; 
    
  // Event 'staticstart' Call
  nSdkInstance.ggPM("staticstart", nielsenMetadata);
</script>

Tracking Code Components

The tracking code includes

• Static Queue Snippet
• SDK Initialization
• Content Metadata
• staticstart Event

Static Queue Snippet

The static queue snippet allows the SDK APIs to be called while the actual SDK and configuration file are still being downloaded. As the queue can capture all API calls before the download completes, there is no wait time. Once the SDK is available, the API calls will transition from directing to the queue to the SDK seamlessly.

!function(t,n){t[n]=t[n]||
{
  nlsQ:function(e,o,c,r,s,i)
    {
      return s=t.document,
      r=s.createElement("script"),
      r.async=1,
      r.src=("http:"===t.location.protocol?"http:":"https:")+"//cdn-gl.imrworldwide.com/conf/"+e+".js#name="+o+"&ns="+n,i=s.getElementsByTagName("script")[0],i.parentNode.insertBefore(r,i),
      t[o]=t[o]||{g:c,ggPM:function(n,e,c,r,s){(t[o].q=t[o].q||[]).push([n,e,c,r,s])}},t[o]}
    }
}
(window,"NOLBUNDLE");

SDK Initialization

While creating an SDK instance, initialize the SDK by calling:

Initialization API Call

NOLBUNDLE.nlsQ("PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX", "",{nol_sdkDebug: "debug"})

When the initialization call is made, a unique static config file, <apid>.js, will be downloaded based on the apid and cached by the client-side browser(s).

Once the static config file is downloaded, the SDK will be fully downloaded and initialized. All SDK modules are included in one file: "nlsSDK600.bundle.min.js".

Content Metadata

Metadata can be passed through key-values using the Nielsen reserved keys. The tracking code includes the Nielsen reserved keys and placeholder values.

Pass dynamic metadata for the keys with the <metadataPlaceholder> value (e.g. section: ).

staticstart Event

There is only one event call required:

nSdkInstance.ggPM("staticstart", nielsenMetadata);

The content metadata object is passed as a parameter when calling 'staticstart' event . To know more about configuring metadata refer Bundled SDK - Static#Configure_Metadata.

Pass App ID in Initialization Call

Pass the unique App ID in the first parameter of the initialization call, <apid>.

Example SDK Initialization

var nSdkInstance = NOLBUNDLE.nlsQ("PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX", "nlsnInstance", {nol_sdkDebug: "debug"});

The initialization call has three parameters:

Parameter	Description	Values
apid	Unique ID assigned to player/site.	PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX
instanceName	Name of SDK instance	Any string value
nol_sdkDebug: "debug"	Enables Nielsen console logging. Only required for testing	{nol_sdkDebug: "debug"}

Update <apid> with the AppID provided.

Configure Metadata

Map the Nielsen keys to variables so that the content metadata is dynamically updated.

The Nielsen reserved keys are:

Key	Description	Data Type	Value	Required?
type	asset type	fixed	'static'	Yes
assetid	Unique ID for each article	dynamic	custom (no Special Characters)	Yes
section	section of each site (e.g. section value should be first level in page URL: website.com/section). Limit to 25 unique values	dynamic	custom	Yes
segA	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segB	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segC	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	fixed	custom	No

The values passed through the Nielsen keys will determine the breakouts that are seen in reporting. The custom segments (A, B & C) will roll into the sub-brand. To not use custom segments A, B and C, do not pass any value in these keys.

Aggregation Limits There are limits on the number of unique values that can be aggregated on in reporting. The specific limitations by key are:

Key	Aggregation Limit
section	maximum of 25 unique values (section <= 25)
segA	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segB	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segC	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)

Opt-Out

The site must provide a means for the user to opt-out of, or opt back into, Nielsen Measurement. A user can opt-out if they would prefer not to participate in any Nielsen online measurement research. To implement the opt-out option, include the following two items in your privacy policy

• A notice that the player includes proprietary measurement software that allows users to contribute to market research (such as Nielsen TV Ratings)
• A link to the Nielsen Digital Measurement Privacy Policy at https://www.nielsen.com/digitalprivacy

On the Nielsen Digital Measurement Privacy Policy page, users can click Choices to read more detailed information about the measurement software, learn about their options with regard to Nielsen measurement, and, if they do not want to participate in Nielsen online measurement, click a link to receive an opt-out cookie.

The following paragraph is a template for an opt-out statement, the properties may feature Nielsen proprietary measurement software, which will allow users to contribute to market research, such as Nielsen TV Ratings. To learn more about the information that Nielsen software may collect and your choices with regard to it, please see the Nielsen Digital Measurement Privacy Policy at https://www.nielsen.com/digitalprivacy.

Opt Back In

Once users have opted-out, they can choose to opt back into Nielsen Measurement at anytime by selecting the opt back in link on the Nielsen Digital Privacy Policy page. When a user selects the link, their opt-out cookie will be deleted and they will be able to be measured.

Going Live

Once the DCR Tracking Code is added to Instant Articles, Nielsen will validate the implementation. Following Nielsen testing, users need to make a couple of updates to the initialization call to ensure that the site is being measured properly.

1. App ID: Ensure that correct <apid> is used during initialization

   'PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'
   

2. Debug Logging: Disable logging by deleting {nol_sdkDebug: 'DEBUG'} from initialization call.
   • Example Production Initialization Call - Refer to the production initialization call below:

     var nSdkInstance = NOLBUNDLE.nlsQ("PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", "nlsnInstance");
