Microsoft Invest - Run rich media creatives on mobile inventory

This document describes how to set up your rich media creatives to serve on mobile devices. It also contains a list of media types supported by each major seller. Note that this is not an exhaustive guide to targeting and running mobile ad campaigns; for a complete description of our mobile targeting, see Buy Mobile Inventory via RTB.

Interstitials

Buyers can target and purchase interstitial impressions by using creatives with sizes appropriate for mobile interstitials. Typical mobile interstitial sizes include:

When setting up an interstitial creative, buyers should select the Standard Banner media type and enter one of the interstitial creative sizes listed above. The above sizes are the most common interstitial sizes and apply for all operating systems. Although these creatives will serve as interstitials on mobile devices, they are really just standard, static banner creatives.

MRAID expandables

You can run expandables on mobile app inventory using MRAID creatives. These are trafficked as Standard Banner media types in common mobile sizes such as 300x50. Select Third-party creative and enter the HTML or JavaScript code of your MRAID creative in the Tag text area.

Here is an example MRAID creative; note that the line at the top including "mraid.js" is required for it to work:

<script src="mraid.js"></script>
<img src="media/png" style="display: none" onerror="
        (function(img) {
            var params = {'placementId': '123456','clickUrl':'${CLICK_URL}','clickEvent':'advertiser','externalAdServer':'AppNexus'};
            var req = document.createElement('script');
            req.id = params.scriptId = 'the-company-script-' + (window.theCompanyScriptIndex = (window.theCompanyScriptIndex||0)+1);
            params.clientTimestamp = new Date/1000;
            req.src = (window.location.protocol == 'https:' ? 'https' : 'http') + '://ads.the-company.com/mraid-ad.js?';
            for (var k in params) {
                req.src += '&amp;' + encodeURIComponent(k) + '=' + encodeURIComponent(params[k]);
            }
            img.parentNode.insertBefore(req, img.nextSibling);
        })(this);
    "/>

MRAID-certified

Creatives that are MRAID-certified may serve on external mobile supply sources. During the Microsoft Advertising creative audit process, MRAID creatives with expandable characteristics will only be flagged with the MRAID technical attribute and not with the expandable technical attribute.

Non-MRAID-certified

Non-MRAID creatives that have expandable features will not serve on external mobile supply. If there are expandable features, our audit team will mark these creatives as having an Expandable media type. Expandables will not serve on external mobile supply.

Supported rich media types by seller

All of the mobile sellers in this table support both interstitials and expandables.
