Facing ads impression discrepancy on our side

[Arun Kumar]

Hi Team,

I'm trying to record the ads impression on my side, so When ads start playing after 2 sec of that ad play I'm recording that ad impression, but getting around almost 40-50% of discrepancy b/w the GAM data and my data, I'm recording the high data.

As per my knowledge, Google record ad impression after 2 sec of the ad playing, and the ad should be at least 50% in the viewport.

Can you please suggest how can I resolve this discrepancy issue on my side, When should I record ad impressions on my end, Is there any specific event fired by IMA SDK when on which Google count for Impression, or Is there any specific network request or something other matrices fired by Google?

Hi Arun,

Thank you for reaching out to our support forum.

For your use case, you may utilize the google.ima.AdEvent (https://developers.google.com/interactive-media-ads/docs/sdks/html5/client-side/reference/js/google.ima.AdEvent), then check if the IMPRESSION callback has been triggered.
 

This message is in relation to case "ref:_00D1U1174p._5004Q2nsw0S:ref"

Thanks,

Hi Team, Thanks for your response.

I already checked with the IMPRESSION callback, As I mentioned earlier I'm recording impressions on my backend after Ad Played for at least 2 Sec. which is triggered after the IMPRESSION callback even STARTED callback is called after the IMPRESSION callback but still, I'm getting around 40% discrepancy in b/w my recorded impression and GAM Impressions.

Hi Team,

I have shared two files on the given link, one contains the discrepancy of data and URL where you can see the player working and the other contains the sample code of how I'm recording the Imp.

Hi Arun,

Thank you for responding back with the requested information. Allow me to raise this (including the reports and discussion thus far) to a wider team for further checking and to get their insight as well. I'll update this thread the soonest I hear back from them.

Hi Arun,

 

You are likely seeing a discrepancy due to the traffic verification process that Google Ad Manager performs before registering an impression as valid. This filtering occur entirely within Google Ad Manager, and therefore is beyond the scope of the SDK support forum, but you can read more about the process in the article linked at the bottom of this help center page.

 

Thanks,
