Up to 60 seconds

Standard file upload size:




Third-party VAST 2.0 or 3.0 is also accepted. Only InLine Linear ads are accepted; Non-linear and wrappers are not accepted. VAST from a third party server must contain at least one MP4 media file: but it is strongly advised that the following be in the VAST:

  • MP4 high bitrate
  • MP4 low bitrate
  • FLV high bitrate
  • FLV low bitrate
  • (Optionally, but preferably) WebM high bitrate
  • (Optionally, but preferably) WebM low bitrate

"Low bitrate" is around 400-600kbps, "High bitrate" is around 1000-1200 kbps. Multiple bitrates are recommended for broadest acceptance, with at least one version with a bitrate less than 400kbps for mobile compatibility.

Ideally, the low bitrate versions are encoded at a lower resolution (i.e. 640x360 for 16:9 video, 640x480 for 4:3 video) if the high bitrate version is at a higher resolution. This is because the quality of a high resolution video at low bitrate will be poor, and some devices, especially mobile, may have difficulty playing very high resolution (i.e. 1080p) video. For more information, see: under 'Universal Ad Package' for guidelines.


We also do accept POP under ads for HTTPs links. A type of window that appears behind the browser window of a Web site that a user has visited. In contrast to a pop-up ad, which appears over (on top of) the browser window, a pop-under is less obtrusive as it hides behind other windows. Pop-unders are used extensively in advertising on the Web, though advertising is not the only application for pop-under windows.

Tracking Macros

The following macros can be used in destination click URLs, JS/Iframe tags or impression tracker.

Passes name of app that the ad is being served on

(e.g.”Tank Recon 3D (Lite)”)

*We suggest to use [ADX_ADS_DOMAIN] macro instead of [ADX_BUNDLE_ID] since [ADX_BUNDLE_ID] handles only in app and [ADX_ADS_DOMAIN] handles both site domain and app bundle within one campaign.

Conversion Tracking

What Is It?

Conversion pixels allow you to track the success of your campaign by reporting back an action that the user has completed on your website/app after arriving through an advertisement. Once conversion pixels are placed, you will be able to see how many conversions are generated from each site, placement, banner, etc. Conversion pixels can be used to track actions such as:

  • The user makes a purchase.
  • User signs up for your site.
  • User submits their e-mail address.
  • User arrives at your “goal page”.
  • Any other event or action on your website/app.


How It Works

A conversion pixel is a short line of code that you will place on your conversion page (“Thank You” page). We generate a unique transaction id value when your ad is clicked by a user. This transaction id value can be passed through to your campaign URL by using [adx_txn_id] macro, we need you to store and send back the information that we called ‘adx_txn_id’.

At a later point in time, when the user arrives at your thank you page and loads the conversion pixel our server uses the transaction id which was passed via your landing page URL and saved at your end and passed to the conversion pixel replacing the macro [adx_txn_id] to record conversion against the impression.

You will then know which placement on which domain generated the conversion, and which specific creative the user clicked on. This information will be available in your campaign statistics.

To do this:

Enter the landing page link that you use for the ad in the Click URL. Add the parameter for our adx_txn_id at the end of the URL.
[adx_txn_id] is a required id for us to track the conversion.
The Click URL setup should look like:[adx_txn_id]

You can define the name of the variables according to your tracking system. For example, define [adx_txn_id] as qs=, or subid= or v1=. This depends on your tracking system.

After clicking on one of your ads, users are redirected to your web property and will hopefully move through your funnel to complete the desired action. This action could include making a purchase, filling out a form, submitting email information, or some other event. In any of these cases, the successful action is referred to as a conversion. Conversion pixels are used to count the number of users that completed an action and attribute that conversion information back to the campaign.

Place the below pixel on your website’s conversion page, before the closing body tag.
<img src=”[adx_txn_id]” border=”0″>

Once you have updated your website with the conversion pixel, users that arrive at this page by clicking your ad in the future will be counted as conversions.
