Automatic Optimization Rules (Required)
Auto-optimization is strongly recommended for VPN campaigns due to high traffic volumes. It helps control spend and automatically exclude underperforming zones.
General principle: the faster the target action (e.g. app install), the shorter the optimization interval should be.
Suggested optimization triggers
CPI campaigns
5–10K impressions + at least 1 conversionScreenshot from the HilltopAds advertiser account
CPT campaigns
20–30K impressions + at least 1 conversion

Or optimize strictly by eCPA per event

These rules allow you to scale effective zones faster while automatically limiting spend on low-performing traffic.
Budget Recommendations
Testing budgets should depend on GEO tier and the number of countries in the campaign.
Recommended daily budgets
Tier-1 GEOs: $200–300 per day
Tier-2 & Tier-3 GEOs: around $100 per day

This budget allows you to collect enough data to make correct optimization decisions instead of killing campaigns too early.
Optional: MultiAds & Pre-Lander Testing
As an additional testing step, you can use MultiAds, which allows multiple destination links or pre-landers within one campaign.
To enable MultiAds:
Contact your HilltopAds account manager
What to test
Different pre-landers
Messaging angles (privacy, speed, geo-unblocking, etc.)
Rotating multiple pre-landers often helps identify stronger combinations without increasing traffic costs.
Make sure all creatives and pre-landers comply with HilltopAds policies. Detailed requirements are available in the Help Center.
