6.0.0

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 Step 3.

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. Refer to the Going Live section to know about updating the AppID to production after testing is completed.

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 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 http://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 http://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");

5.1.1

Prerequisites

To start using the Browser SDK, the following details are required:

  • App ID (apid): Unique ID assigned to the player/site and configured by product.
  • sfcode: Unique identifier for the environment that the SDK should point to. During testing, please use the sfcode as "dcr-cert".

If you do not have any of these pre-requisites or if you have any questions, please contact our SDK sales support team.

Import Library

In the HTML head section of each page, call the Nielsen library using the script tag, as shown below. 

   <script type="javascript" src="http://secure-dcr-cert.imrworldwide.com/novms/js/2/ggcmb510.js"></script>

Define GlobalParams

  <script type="javascript">
   var _nolggGlobalParams =
     {
       sfcode: "dcr-cert",
       apid: "TXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
       apn: "test-setup",
       nol_sdkdebug: "console"
     };
    </script>

Initialize SDK

Initialize Browser SDK as soon as the Parent / Main Page is loaded. During the initialization, custom parameters can be appended to the global parameter object. These custom (extended) parameters are optional. Use them only if the player application can handle the custom parameter data.

The Nielsen Browser SDK supports multiple processing instances. To create an instance, call the getInstance() function 

    var nSdkInstance=NOLCMB.getInstance(instanceName);

All subsequent calls to getInstance with the same instanceName will return an already created SDK instance with that name. This will allow accessing the same object from different parts of the code.

The "instanceName" parameter is optional and will be set to "default" if missing. To use a single default SDK instance, call 

    var nSdkInstance=NOLCMB.getInstance();

In order to initialize the SDK, parameters must be passed when calling the initialization function (ggInitialize). The available parameters are listed in the table below.

Parameters Description Value Required? (Y/N)
apid UniqueID assigned to player/site. There are two IDs provided for
  1. Test: begins with ‘T’ and is used for testing, and
  2. Production: begins with ‘P’ and is used when testing is completed in live environment.
 Nielsen assigned Yes
apn User-defined string value for describing the player/site Client-specified Yes
sfcode Location of collection environment. During testing, all traffic should be directed to dcr-cert. "dcr-cert" – testing

"dcr" – production || Yes

nsdkv Nielsen SDK Version currently being used. Nielsen assigned (‘511’ for Browser SDK 5.1.0, etc.) Yes
nol_sdkdebug Enables Debug Mode which allows output to be viewed in console. "console" No 
    var gg = window.NOLCMB.getInstance(instanceName /*optional*/);
    gg.ggInitialize(window._nolggGlobalParams);

Fire Event: staticStart

Use staticStart to pass details about content section. The CMS data must be passed as a JSON string (before closing <body>). 

    ggPM(staticStart, metadataObject);

Trigger staticStart, as below, for the static content when the page is loaded. 

    gg.ggPM("staticstart",
    {
        type:"static",
        assetid:"static123",
        section:"siteSection",
        segA:"segmentA",
        segB:"segmentB",
        segC:"segmentC"
    }
    );


Key Description Values Reported for Static?
type Type of audio / video Measurement content (content, etc.). "static" No
assetid Unique ID assigned to content custom No
assetName Unique name for the asset custom No
section Section of the site custom No
segA Custom Segment A custom Yes
segB Custom Segment B custom Yes
segC Custom Segment C custom Yes

Dynamic Metadata

An alternative method for passing in assetid, section, segA-segC (if used), is to pass these values dynamically instead of hardcoding these values per site section. The code below provides an example of how this can be achieved. 

    <script type="text/JavaScript">
    var temp =
    $("meta[property='og:url']").attr("content").replace("https://xyz.com/discover/","");
 
    var _nolggGlobalParams =
    {
        sfcode: "dcr-cert",
        apid: "TXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
        apn: "test-static"
    };
    var gg = NOLCMB.getInstance(_nolggGlobalParams);
    gg.ggInitialize(_nolggGlobalParams);
    var staticmeta =
    {
        type: "static",
        assetid: "temp",
        section: "temp",
        segA: "Test Site",
        segB: "Videos",
        segC: "Comedy"
    };
    staticmeta.section = temp;
    gg.ggPM("staticstart",staticmeta);
    </script>

Tagging a Page

Refer to the sample code for Tagging a page with static <Page Measurement> content.

Nielsen Measurement Opt-Out Implementation

As a global information and measurement leader, we are committed to protecting the privacy and security of the data we collect, process and use. Our digital measurement products are not used to identify the consumer in any way, but they help us and our clients measure and analyze how consumers engage with media across online, mobile and emerging technologies, and offer insights into consumer behavior.

When the user wants to opt in or opt out of Nielsen measurement, a new dynamic page (with content similar to [1]) should be displayed.

For more details, refer to Opt-Out Implementation and Nielsen Digital Privacy.

Pre-Certification Checklists

After the website is ready to be sent for Nielsen Certification, please go through the Pre-Certification Checklist and ensure the webpage behaves as expected, before submitting to Nielsen.
