IV. How to Check and Read Rejection Reasons

  1. Rejected Campaign

    If a campaign was not approved by the Content Quality Team, you will see the “Rejected” status in the Health status column (Campaigns tab in the Voluum panel).


    You can also mark the campaign and click Edit to see the rejection reason in the campaign creation form.


    When you click on the Rejected status, a new window will pop up. Here you can find a section called Comment for Client, where an explanation of the rejection reason is displayed. Note, the Health Status console can sometimes also contain additional information: notes from our Content Quality Team, when your campaign is in pending status, or even when it is already approved.


    The Health Status console contains much more information about your campaigns. To find out more, please check DSP Campaign Statuses documentation.

  2. Rejected Ad Elements

    Some creatives within your campaign may not be accepted. In order to check if some creatives are rejected, please go to the panel, choose the campaign you want to check, click on ‘EDIT’ and then go to the ‘CREATIVES’ tab. On the list of the uploaded creatives, you will see an applicable mark next to each creative:

    - the green ticks for the accepted ones;

    - the red icons for the rejected ones;

    - the yellow icons for the ones which are pending for approval.

    To check the rejection reason, please hover over the red mark next to a Creative.


Voluum DSP as well as Publishers that cooperate with the platform have their own Advertising Policies that have to be respected in order to use our Platform and promote certain products/services on Publishers’ sites. That is why in order to have a campaign approved, both the Policies of Voluum DSP and the selected Ad Exchange have to be followed. We can distinguish a few different groups of rejection reasons and comments for clients that may appear after the campaign is rejected or when it is pending.

You can receive two types of comments from the Moderation Team:

  • A Rejection Reason - when a campaign is rejected because of either prohibited content on the websites and/or lack of appropriate creatives/headlines,

  • A comment or suggestion from the Moderation Team - when your campaign is approved or pending.

When your campaign is rejected, you are always provided with a rejection reason.


A standard rejection reason consists of:


It defines whether certain campaign elements violate Voluum DSP’s policy or the selected Ad Exchange’s guidelines.


There are three main groups of rejection reasons:

  • Against Compliance - a campaign contains elements that violate Voluum DSP’s policy and cannot be accepted on the Platform.

    This basically means that a campaign cannot be accepted on any Ad Exchange that cooperates with our platform because of elements/products/services or using practices that are prohibited by Voluum DSP, for example nudity, pornography or cloaking. More information about prohibited content and campaign practices can be found here.

  • Against Ad Exchange Guidelines - a campaign contains elements that violate the guidelines of the selected Ad Exchange.

    Rejection reasons from this group are added when no campaign elements violate Voluum DSP’s policy, but some of them don’t follow the guidelines of the Ad Exchange. This is why it can’t be accepted on this particular Ad Exchange, but can be approved for others that are usually recommended in the rejection reason. After fixing elements mentioned in the comment from the Moderation Team, a campaign can be approved. Information about required elements or prohibited content on certain Ad Exchanges can be found here.

  • Issues - the Moderation Team came across some kind of problem during the approval process. It may be related to technical issues, complaints, test campaigns, terminated cooperation with a publisher, TMT scan issue, Policy updates, etc. 

    Depending on the issue, the campaign:

    - can be accepted for the selected Ad Exchange after you fix the elements described in the rejection reason. For example, fixing redirects that don’t work from a landing page to an offer page,

    - cannot be approved for the selected Ad Exchange but can be accepted for other Publishers’ sites that are suggested in the comment. For example, when the cooperation with a certain publisher is terminated,

    - cannot be approved on any Ad Exchange. For example, when the account is suspended.

It defines which campaign elements/contents/practices violate either Voluum DSP’s policy or the guidelines of the selected Ad Exchange.


The most common Rejection Reason Types in the mentioned above Rejection Reason Groups are:

  • Against Compliance:

    - Prohibited Content,

    - Prohibited Campaign Practices,

    - Creative Violation,

    - Headline Violation.

  • Against Ad Exchange Guidelines:

    - Vertical Violation,

    - Product/Offer Violation,

    - Landing Page Content Violation,

    - Creative Content Violation, 

    - Icon Image Violation,

    - Domain Violation, etc.

  • Issues:

    - Ad Exchange Issue - Policy Update,

    - Category Relevance Issue,

    - Tech Issue (error),

    - Tech Issue (redirect),

    - TMT issue, etc.

A few of these types are described above in section ‘Rejection Reason’ where you can also find examples.

It this part of a rejection reason provides an explanation in one or two sentences on why a campaign got rejected.


It this element signals that a campaign can be approved for the selected Ad Exchange if the mentioned elements are fixed/removed/added


This part of a rejection reason is used only when every campaign element follows Voluum DSP’s policy, but some elements don’t meet the Ad Exchange's requirements, in this case the Moderation Team suggests other Ad Exchanges that can accept such content without making any changes. This way, Advertisers can save time that by not having to fix the campaign


A screenshot is supposed to show what the problem is and make it easier to understand the rejection reason. It may show only examples of elements that need to be fixed/removed and it doesn’t have to point out every single detail that has to be changed. Screenshots are not added to all rejection reasons.


Other comments:

When your campaign is approved it means that the content visible on landing pages and offer pages is appropriate for Voluum DSP and the Publisher that was selected, in this case you usually don’t receive any comments from the Moderation Team. Usually either none of the creatives or only a few of them are rejected, and a reason can be visible next to them in the panel.  

You rarely receive a comment to the whole campaign from the Moderation Team when a campaign is approved. However, you may receive one when the Team wants to suggest trying other networks with similar or better traffic for your campaign or to advise which elements can be changed. Those suggestions are not obligatory and rather serve as additional information. 

When your campaign is waiting for approval longer than the standard time, it is usually because of external pre-approval. In this case, you are also informed about it in a comment from the Moderation Team.

The difference between comments:

  • Please change mentioned elements or choose another Ad Exchange - a campaign needs only a few fixes to be approved and can also be approved on other Ad Exchanges without any changes of the content.

  • Please choose another Ad Exchange - is used by Moderation Team when, for instance: there are too many elements that would have to be changed to get the campaign approved, when the category of a campaign is prohibited on a particular Ad Exchange, when the quality of landing pages, offer pages and/or creatives is too low for an Ad Exchange yet the campaign can be approved for other Publishers.
