Total Load Size
Measures the total load size of all requests needed to load the creative. Includes pixels and 4th party data.
The number of HTTP requests made, including any pixels. The IAB suggests no more than 10 requests during initial load.
Measures the time the CPU was busy loading the ad. Especially on mobile devices, CPU cycles should be kept at a minimum.
Measures the time it takes for the DOMContentLoaded event to fire. Altough sub-load data may still be loaded after, it's a useful point of reference.
Determines the exact dimensions of the ad. Uncommon sizes may have to be investigated further.
The amount of RAM the creative claimed when fully loaded. This includes memory used by any iframes.
Checks if the ad loads all requests via https. Since SSL became a common standard, it's important to make sure the tag is SSL-compatible.
The number of iframes the creative adds to the page. Keep it low, since iframes require quite some memory.
Detects if the ad plays videos content. Videos blow up sub-loads and increase bandwidth considerably.
Usually deprecation-warnings by Chrome. These warnings may need attention, as any time in the future the ad may stop working properly.
This test detects if the ad is responsive on mobile devices. If not, it will determine if the ad is small enough to be displayed correctly.
Detects if for example a 300 x 250 ad is actualy 301 x 251 in size. This happens often when measurement pixels are not hidden, leading to visual artifacts on the publisher's page.
Detects if the creative actually paints something on the screen. If an ad returns blank, this can be due to targeting, JS errors or SSL issues.
Blocked by AdBlock
Detects if the ad will be blocked by common ad blockers. Ask your advertiser to provide adblock-free tags, as otherwise discrepancies between systems may be considerable.
It's been a while since document.write() has been banned in the ad industry. Some notorious ad server vendors are still loading scripts synchronously, delaying page render and slowing down the page.
If you require the creative to have a high-contrast border, this test will alert you if no border is detected.
The name of the third-party ad server vendor. If a vendor is not on the list, you can create a custom list of vendors for detection.
3P Domain Screening
This test fails if assets are loaded from 3P or 4P domains that are not on your white-list of accepted vendors. Use this test to ensure GDPR/CCPA compliance with vendors you're doing business with.
Detects if the ad loads requests that return a 404 HTTP status code. Missing items and broken links are never a good sign and may have to be investigated further.
Dialogs & Modals
This test checks if an ad shows a dialog. Users have to click 'OK' in order to continue using the page, which has a negative impact on user-experience.
Detects how many measurement pixels are fired. This includes pixels for impressions logging, viewability and tracking.
Some vendors use the HTML5 localStorage object to store unique identifiers in the user's browser. In the light of privacy laws, you may want to investigate if Personally Identifiable Information (PII) is involved.
Click Tracking Macro
As a publisher, you want to detect clicks on third-party ads. This test makes sure you've added your click macro to the tag (i.e. didn't forget it).
Landing Page URL
Reports the final URL of the page that opens when a user clicks on the ad.
Landing Page Redirects
The number of redirects before the final landing page is opened. This should be kept at a minimum to improve the user experience.
Landing Page Target
Determines if the landing page opens in a new tab (which is common) or in the same tab.
