In order for your creatives to serve on Google AdExchange (AdX) and AppNexus inventory, they must pass the human audit, as well as be approved by AppNexus' and AdX's automated auditing systems. Yieldr handles submitting your creatives to the audit queue and programmatically retrieves the approval status. You can find the audit status of your creatives within the Yieldr Ads platform under "Advertiser Name > Creatives". Simply hover over the green icons under the column "Audit Status" and the pop up will display the status of that creative size. 

Creative Audit Process

Creatives are both audited by the AppNexus human audit, and are evaluated for compliance with Google Ad Exchange's creative standards. Your creative will therefore have two audit statuses:

  • The "Audit Status" will reflect the AppNexus audit status. See the Creative Standards and Auditing article for more information about AppNexus' standards. Creatives with an approved "Audit Status" can serve on AppNexus inventory.
  • The Google "Audit Status" will reflect the Google AdX audit status. See Google's Ad Exchange Policies for more information about AdX's standards. Creatives with an approved Google "Audit Status" can serve and bid on AdX inventory. 

AppNexus Standards & Audit

Yieldr invests significant resources towards the safety and quality on both sides of transactions taking place on the Yieldr platform. Buyers on the Yieldr platform may submit their creatives for human auditing by the AppNexus audit team. AppNexus requires all buyers to have their creatives audited, this is why when targeting AppNexus in the Yieldr platform your creatives will automatically be submitted to their auditing.

This manual audit process includes checking the creatives against their technical- and content criteria, as well as offer type categorization to enable the seller protection features on the Yieldr Ads platform. In addition to auditing your creatives on AppNexus Standards, their Audit Team also evaluates creatives against the requirements of several sellers, including Microsoft.

Additionally, all creatives (default for ad tags) on the ads platform are continuously monitored for overt malvertising threats and suspicious behavior, regardless of audit status. Our Sherlock technology will also add additional metadata to your creatives.

Process & Procedure

When a creative is introduced into the AppNexus exchange, either through a user interface or via API (unless it is opted out of auditing), AppNexus’ team of human auditors will evaluate it against their creative standards, and will tag the creative with metadata. AppNexus also audits against the Microsoft Ad Exchange standards. Auditing fees are charged per creative, regardless of the outcome of the audit. That is why we suggest you review all your creatives for functionality and policy compliance prior to submission to the audit, to avoid fees for failed audits.

Sellers use the creatives' audit status and metadata to approve or ban them on a categorical or individual basis. We allow each seller of inventory to determine the types of creatives that are allowed to serve on their inventory, including whether to allow un-audited ones.

We also allow sellers to apply trust levels to individual buyers. For example, a seller can apply maximum trust to a buyer. This seller will then accept all creatives from those buyers, regardless of the audit status or metadata properties of that buyer’s creatives.

Creatives must pass through the auditing process to run on AppNexus' real-time inventory (with the exception of resold inventory, where publishers have the option to allow unaudited creatives to run). Moreover, all aggregators, including Microsoft, require creatives to be audited by the AppNexus team prior to running on their inventory.

Some reasons for choosing not to submit your creatives to the audit process:

  • If the creative will run only on your direct publishers, it does not need to be audited.
  • If the creative is not ready to serve (e.g. you wish to edit the content later, or the third party offer has not been activated, etc.).

After a creative has passed the audit and is subsequently altered in the AppNexus system, its audit status will be automatically reset so that it can be re-audited. If a creative is altered outside of AppNexus, e.g., if it is redirected to another creative or graphical assets are altered, it must be manually submitted for a re-audit.

Because clients are charged a fee for each audited creative, they typically submit creatives for the AppNexus audit only after confirming themselves that the creative functions correctly.

Auditing Timeline and Priority

Creatives are audited in the order they are received, with a target completion time of one business day counted from the time of submission. Priority audits, available for an additional fee, are completed within two business hours. To enable priority audits for your account, please contact our Support Team.


Creatives opted in for AppNexus auditing will be audited by both manual and automated processes. ALL active creatives, regardless of whether they are opted in, will be continuously monitored for malvertising prevention.

If you receive the feedback, "Creative is Unauditable - Creative is Not Displaying Properly" the creative may have been flagged by Sherlock for serving blanks. We do not charge for re-auditing blank creatives and the impact on campaigns is generally low, as most associated creatives or campaigns are automatically set to inactive or expired when they contain blank-serving creatives. If a campaign is still active however, the re-audit serves as a way to alert clients that their creative is displaying as a blank. Once this has been corrected, the audit team will re-audit the creatives.

Expired Creatives

If a creative has either not served an impression, and/or has not been modified in 45 days, it will automatically expire and its status will be set to inactive. Expired creatives that have previously passed the audit may be reactivated, however their priority audit status will not carry over. All expired creatives must be resubmitted for the audit and will be charged the standard auditing fee, before they can start serving impressions again.

Auditing Feedback

If your creative is rejected by the AppNexus audit, a rejection reason will be provided. Consult the table below for more information on likely causes of audit rejections:

Modify your Creative and Resubmit

Review and Confirm Rejection Feedback

You will be provided with a rejection reason if your creative is rejected by the audit. Find the reason that was provided within the "Rejection Reasons" table above and review the likely cause. Once you've identified the cause, review your creative and it's settings to confirm the validity of the rejection.

Modify your Creative

If your creative has been rejected, you'll have to revise it to meet the necessary requirements. Revision could involve modifying the creative file itself, or settings associated with your creative that are made within Console or via the API. 

Apply for a Re-Audit

Once you have revised your creative to meet the necessary requirements, apply for a Re-audit. If you find that it was misaudited, submit a support request to the Yieldr Support Team.
