DoubleVerify

What is DoubleVerify?

DoubleVerify provides online media verification and campaign effectiveness solutions for marketers, advertisers and digital publishers.

Why use this integration?

This integration is useful if, for example, you are network or publisher and have received a DoubleVerify tag from an advertiser looking to measure DoubleVerify viewability and attention signals on their campaign.

DoubleVerify has integrated the Celtra Viewability Observee API, which ensures measurement is accurate across all Celtra display formats.

This integration is useful for measurement, and does not include support for blocking, e.g. using dvbs_src.js tags, which should be completed separately.

How to use DoubleVerify with Celtra

To append a DoubleVerify tag to your Celtra tag, follow the instructions by format below.

Display

For display creatives, do the following:

Append the DoubleVerify tag to the Celtra tag when inserting them into your 1st party ad server.

    

    
        
            <!-- Celtra tag -->
<div class="celtra-ad-v3">
  <img src="data:image/png,celtra" style="display: none" onerror="
        (function(img) {
            ...
        })(this);
    "/>
</div>
<!-- DoubleVerify tag -->
<script src="https://cdn.doubleverify.com/dvtp_src.js/..."
    type="text/javascript"></script>

While all DoubleVerify tags are equipped to utilize Celtra’s Viewability API, alternative methods for finding the creative element for measurement may be prioritized by their platform in any given session. To force DoubleVerify to prioritize the usage of Celtra’s API over other methods, update the ‘adsrv’ parameter to ‘adsrv=179’.

In this case, a DoubleVerify 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 DoubleVerify script automatically detects the neighboring Celtra tag and an Celtra-DoubleVerify integration ensures the correct HTML elements are measured for viewability across all creative formats.
If you have included the DoubleVerify SDK into your apps, the DoubleVerify script will also automatically communicate with it to measure viewability.
