Geo targeting means showing your ads to people in a specific location, like a country, state, or even a small city. The best way to use it is to start small and focus on places where your product can really serve people well. If you sell delivery services, it makes sense to target only areas you can reach. Check which locations bring more clicks and sales, then shift more budget there. This saves money and improves results. What simple location filter has worked well for others?
