To scale push notification traffic across different regions, the first thing to do is test traffic in a few new countries. This helps you understand which regions respond better to your affiliate offers. Once you find areas with good results, you can slowly increase your daily budget and bids there. Also, it helps to adjust your ad content to match local language and culture. Some networks let you target by language or device, which can make your campaign more effective. You can also split campaigns by region to better track what's working in each place. Just make sure your offer is allowed in the region you're targeting and that your landing page loads fast in that area. Pacing your spend and checking performance daily will help you scale without wasting money. What are your thoughts on this?
