This guide will show you how to enable Digital Content Ratings (DCR) Static measurement on Google AMP.

== Import AMP Analytics Javascript Library ==
If you have not already, you will need to import the AMP JS library in the <code><head></code> of your webpage in order to make an AMP page:
<syntaxhighlight lang="html"><script async src="https://cdn.ampproject.org/v0.js"></script></syntaxhighlight>


Next, please ensure that the following line is included in the <code><head></code> of the webpage:
<syntaxhighlight lang="html"><script async custom-element="amp-analytics" src="https://cdn.ampproject.org/v0/amp-analytics-0.1.js"></script></syntaxhighlight>
<blockquote>'''Note''': AMP pages require all traffic to be using HTTPS, including the webpage itself</blockquote>

== Specify the Analytics Provider ==
DCR measurement can be added to your AMP pages through the AMP-Analytics element:
<syntaxhighlight lang="html"><amp-analytics type="nielsen">
    <!-- Add Nielsen DCR Tags here -->
</amp-analytics></syntaxhighlight>

For more information on the Analytics type, you can refer to the [https://www.ampproject.org/docs/guides/analytics/analytics-vendors Analytics vendors] section of Google's AMP Developer Documentation.

== Configure Metadata ==
You will need to match the metadata fields on your AMP page with those of your non-AMP page.

=== Metadata Keys ===
The Nielsen reserved keys are:
{| class="wikitable"
|-
! Key !! Description !! Example Value !! Required
|-
| apid || unique ID assigned by Nielsen || <code>XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX</code> || ✓
|-
| apv || current version of the Nielsen implementation || <code>1.0</code> || ✓
|-
| apn || name of the website || <code>My AMP Website</code> || 
|-
| section || section of the site to be measured || <code>Entertainment</code> || ✓
|-
| segA || custom segment to be used to break out reporting || <code>Music</code> ||
|-
| segB || custom segment to be used to break out reporting || <code>News</code> ||
|-
| segC || Reserved custom segment for Google AMP || <code>Google AMP</code> || ✓
|}

The values passed through the Nielsen keys will determine the breakouts you will see in reporting. If you decide not to use custom segments A and B, then you do not need to pass a value in these keys. It is suggested you use the same segments used in non-AMP pages.

=== Metadata for Reporting ===
You can reference the table to determine how the metadata you pass is used to define your reporting structure:
{| class="wikitable"
|-
! Reporting Level !! Key !! Description
|-
| Brand/Sub-brand || apid || brand and sub-brand are determined by assigned App ID passed during initialization
|-
| Section || section || section or category for the AMP page
|-
| Custom Segment A || segA || available segment for custom reporting. Custom segments will roll into the sub-brand
|-
| Custom Segment B || segB || available segment for custom reporting. Custom segments will roll into the sub-brand
|-
| Custom Segment C || segC || Custom segment C is reserved for reporting ‘Google AMP’. The Google AMP custom segment will be available under sub-brand and will include the total metrics for all your AMP pages
|}

If you would like your AMP pages to report into the same reporting structure as your website, we recommend passing the same dynamic metadata in Section, Custom Segment A, and Custom Segment B as you are on your website. This way your AMP pageviews contribute to those aggregations.

=== Aggregation Limits ===
There are limits on the number of unique values that can be aggregated on in reporting. The specific limitations by key are:
{| class="wikitable"
|-
! Key !! Aggregation Limit
|-
| section || maximum of 25 unique values (section <= 25)
|-
| segA || total sum of segA, segB, and segC must be a maximum of 24 unique values (segA + segB + segC <= 24)
|-
| segB || total sum of segA, segB, and segC must be a maximum of 24 unique values (segA + segB + segC <= 24)
|}

== Example Implementation ==
The below is an example implementation of Nielsen measurement on an AMP page:
<syntaxhighlight lang="html"><amp-analytics type="nielsen">
    <script type="application/json">
    {
      "vars": {
        "apid": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
        "prefix": "eu-",
        "apv": "1.0",
        "apn": "My AMP Website",
        "section": "Entertainment",
        "segA": "Music",
        "segB": "News",
        "segC": "Google AMP"
      }
    }
    </script>
</amp-analytics></syntaxhighlight>

You can find more information about dynamic variables on [https://github.com/ampproject/amphtml/blob/master/spec/amp-var-substitutions.md#page-and-content Google's AMP documentation].

<blockquote>'''Note''': append <code>#development=1</code> at the end of your URL to see AMP debug logs in the console. This can be helpful when troubleshooting</blockquote>
