Keep Adsterra for a job when the required format is available, tracking is healthy, source controls are usable and retained outcome economics remain inside the business rule. The existence of alternatives is not evidence that a working campaign should be moved.
Test FroggyAds as an independent paid-traffic option when the buyer needs overlapping formats, another supply source, concentration relief or a different self-service workflow. Use the same destination, accepted event, currency and maturity conditions; no better outcome is guaranteed.
Retain both when they perform distinct measurable jobs or when the evidence shows a resilient split. Deduplicate shared users and outcomes before combining reports. One platform should not receive credit for customers already reached by the other.
The verdict is limited to the reviewed sources, account and campaign design. Reopen it when Adsterra changes formats, funding, estimator behavior, reporting or policy, or when the buyer changes offer, market or accepted-event definition.
