What Is Geo-Targeting in Advertising?
Geo-targeting is the practice of serving ads to users based on their geographic location — country, region, city, or even radius. It’s one of the most important targeting dimensions in digital advertising, particularly for popunder and performance campaigns.
GEO Tiers Explained
| Tier | Countries | Avg. CPM | Conversion Value |
|---|---|---|---|
| Tier 1 | US, UK, CA, AU, NZ | $2–$6 | Highest |
| Tier 2 | DE, FR, IT, ES, BR, MX, PL | $0.80–$2 | Medium-High |
| Tier 3 | IN, PH, ID, NG, PK | $0.10–$0.50 | Low-Medium |
How to Structure GEO-Targeted Campaigns
- Separate campaigns by tier — never mix Tier 1 and Tier 3 in the same campaign
- Set different CPM bids per tier — Tier 1 justifies 5–10x higher bids
- Localize landing pages — currency, language, local trust signals
- Test broad first — run a world campaign to identify converting GEOs before narrowing
- Scale winning GEOs — once Tier 2 countries prove ROI, create dedicated campaigns

Frequently Asked Questions
What is the best GEO for popunder advertising?
For ROI, Tier 1 (US, UK, CA) offers the highest conversion value. For volume at low cost, Tier 3 (IN, PH, ID) offers massive scale at $0.10–$0.30 CPM.
Should I target all GEOs at once?
Only for initial testing. Once you identify converting countries, create separate campaigns per GEO tier to control bids and budgets precisely.
How do I set CPM bids for different GEOs?
Start with the network’s suggested minimum bid per GEO. Increase bids for GEOs that generate conversions until you reach maximum profitable scale.
