Why use this integration?
This integration is useful if, for example, you are network or publisher and have received a ComScore tag from an advertiser looking to measure ComScore viewability and attention signals on their campaign.
ComScore has integrated the Celtra Viewability Observee API, ensuring measurement is accurate across all Celtra display formats on mobile and desktop.
How to use ComScore with Celtra
You'll just need to append your ComScore tag to the Celtra tag (example below) when inserting them into your first party ad server.
Display
For display creatives, add the following:
<!-- Celtra tag -->
<div class="celtra-ad-v3">
<img src="data:image/png,celtra" style="display: none" onerror="
(function(img) {
...
})(this);
"/>
</div>
<!-- ComScore tag -->
<script src="http://b.voicefive.com/c2/[CLIENT_ID]/rs.js#c1=3&c3=[CAMPAIGN_ID]&c4=[CREATIVE_ID]&c5=[PLACEMENT_ID]&c6=&c10=1&c11=[SITE_ID]&c13=[SIZE]&c16=gen&"
type="text/javascript"></script>
In this case, a ComScore tag will typically not contain any ad server macros. Instead, the parameters are already filled with the advertiser's own values.
When inserted into a page side-by-side, the ComScore script automatically detects the neighboring Celtra tag and an Celtra-ComScore integration ensures the correct HTML elements are measured for viewability across all creative formats.
