Checklist for testing gambling or dating CPA traffic without burning budget

[Olevier]

I usually separate the test into five parts:

1. GEO and offer restrictions
2. Device split
3. Source ID tracking
4. Direct offer vs smartlink test
5. Approval rate and lead quality review

The mistake I see often is judging only by initial conversion rate. In gambling and dating CPA, the approval rate and advertiser feedback matter just as much as CR.

For anyone looking at CPA/smartlink setups, CPAGEN has a useful affiliate page
The main thing is to test small, keep clean tracking, and avoid mixing too many GEOs in one campaign until the first conversion data is readable.
