Off the top of my head, you could do geographic bucketing. Take say 100 cities, and only run ads in 50 of them.

Geo tests are useful for sure, but also require a lot of data to get statistically significant results. Any noise in your data (seasonality, PR, etc) has to be taken into account as well. They’re harder to execute in general but can work well.
