Campaign import validation checks whether cost, click, and impression data from external ad platforms match campaigns in an analytics property. GA4 introduced a dedicated validation report in August 2026.
The demo fills a missing social campaign cost value and changes the validation state. In practice, also check that imported source, medium, and campaign identifiers match the UTMs recorded on visits.
A passed check does not prove total spend is correct. Align currency and dates, then compare totals against the original ad platform.
When to use
Use it after importing non-Google ad costs to investigate missing or unmatched campaigns.
