What is a blank impression?

This post was most recently updated on September 22nd, 2021

Blank impressions, blank ads or unfilled impressions are all interchangeable terms in Google Ad Manager. These occur when no ad is served in an ad unit after an auction in your ad server. These can be frustrating for many publishers as they’re leaving money on the table without a good strategy in place. In this post, we’ll take a closer look at blank impressions, what it means for publishers and how you can troubleshoot them when using Google Ad Manager (GAM).

Why are they bad?

Publishers generally want to monetize as many ad impressions as possible to maximize their ad revenue. Naturally, when publishers have unfilled ad impressions revenue decreases.

Although there are many reasons why blank ads can appear, some of the most common ones include not having enough advertiser demand, page loading issues, incorrect CPM floors and many more. It’s an issue that needs to be resolved and fast!

How can I troubleshoot them?

Thankfully there are ways to troubleshoot and fix this issue. You’ll need to start by first checking if you have any unfilled impressions and if so, to what extent.

Next, you’ll need to fix the issue which can be anything from missing house line items in DFP/GAM, not having enough creatives uploaded, missing passbacks, too high CPM floors, etc.

We’ve written an extensive guide on fixing blank impressions that covers all the steps needed here: https://www.monetizemore.com/blog/unfilled-ad-impressions-troubleshooting
