How does geotargeting change CPM rates?

[Daniel]

Geotargeting affects CPM rates because the cost to reach people is different in each location. For example, showing ads in countries with higher spending power usually costs more. Advertisers are willing to pay more to reach people in places like the US, Canada or the UK, so the competition there is higher. On the other hand, CPM is often lower in regions where advertisers spend less, like some parts of Asia or Africa. Also, in smaller cities or rural areas, prices may drop compared to bigger cities. If the goal is to save money, targeting lower-cost regions can help, but it's important to also think about how well the audience matches your offer. Has anyone noticed a big CPM difference between locations?
