USE CASES
Ad verification
The report says a million impressions. It does not say whether the creative was broken on a phone in Mumbai or the landing page fell back to English.
Ads are served by visitor region
Ad platforms pick creative by visitor region. From the office exit you will always see the local version; only the target region’s residential network shows you what the audience saw.
Four things to check
Fix the checklist so periods stay comparable.
- Creative: language, currency and legal notices match local requirements
- Placement: it appears where it was bought and is not pushed below the fold
- Landing page: the redirect chain completes without falling back to a default region
- Hijacking: no third-party ads from channels you did not buy
Split mobile from desktop
Delivery strategy, creative sizes and landing templates usually differ between mobile and desktop in the same region. One user agent across all regions misses half the defects.
