Mismatch in Spending vs. ADX Report

[edison yang]

Hi Google Support,

We are testing ADX . As per the documentation, we treat each received impression event as a billable bid.

However, as shown in the screenshot, our total spend does not match the ADX report — sometimes the difference is quite significant.
(We have already deduplicated by request ID to ensure impressions are not counted multiple times.)

From our view, our system maintenance might cause impression counts to decrease, but we’re actually seeing more impressions than expected, which is confusing.

Thanks!

Best Regards,

Edison

Hello Edison,

Thank you for reaching out.

Since you've created another email thread on this matter, we can follow up there.

In that email, I asked you to clarify what you mean by "we’re seeing more impressions than expected" and to provide your definition of an "impression event" for a billable impression.

Additionally, for more details on how we count impressions, you may refer to our documentation or Help Center:

• Counting impressions and clicks ​​​​
• Impressions expiration ​​​​​​
• Counting impressions and using macros

 

Thanks,
 

Joshua Authorized Buyers API Team
