Window size 0x0 means your ad was not viewable - FouAnalytics in-ad
When measuring ads with FouAnalytics in-ad tags, the window data grid should show normal ad sizes, like 300x250, 320x50, 728x90, and sometimes 300x600, 160x600.
When you see window size = 0x0, that means your ad ran inside an iframe that was 0x0 pixels in dimension. Obviously, humans can't see an ad that is 0x0.
There's one exception to the above observation -- that is responsive ads. These ads start at 0x0, and then resize to one of the normal ad sizes or resizes to cover the entire screen. If the ad does not resize, and remains at 0x0, we label that as pixel stuffing. This form of ad fraud is particularly pervasive in mobile apps, where the apps are deliberately loading as many ads in 0x0 ad slots as possible to maximize fraudulent revenue. In the 3 examples above, the leftmost data grid shows one campaign with 2% of the impressions going to 0x0. The middle data grid is from a different campaign and 13.1% of the impressions went to ad slots of 0x0 pixels. And finally, the 3rd campaign saw 3/4 of their ads (73.1%) not viewable, because they were loaded in 0x0 sized windows.
Something SO basic still happens today. And if you're using legacy viewability vendors like Moat (shuttered by Oracle, servers shutting down September 2024) or other legacy verification vendors, you won't see any of this reported to you. So, you end up buying large quantities of ad impressions that are useless, not because a bot loaded it, but because it couldn't be seen, even if it were loaded by a human using a real device.

Ask your vendor to show you this data. If they can't (or won't) then you know it's time to upgrade your analytics and verification vendor.
Keep in mind the above applies to in-ad measurement in FouAnalytics. When you use on-site measurement tags, the window size corresponds to the viewable portion of the browser, which should be a little less than the total screen resolution. If you add the FouAnalytics on-site tag into a tag manager like GTM ("Google Tag Manager") or Tealium or the Shopify tag container, the window size may register as 0x0. But that is fine because it's not your ad running inside a 0x0 ad iframe.

7 个月What frustrates me is that most platforms still attribute from the "beginning to load". Unless Digital Advertising Alliance changes that, you will be stuck in limbo.
Dr. Augustine Fou said "window size 0x0 means your ad was not viewable," Well the 3x3s and 4.5x1 sure do make a 300x250 look big. That was the other purpose. Make small ads look comparatively large.
