Growing pop traffic can be done in two ways. You can raise your bid to get better placements and more impressions from quality sources. This might bring in users who are more likely to convert. On the other hand, you can try to reach more people by targeting a wider audience. That may increase traffic numbers, but the quality may drop if you're not careful. What works better really depends on your goal. If you want to test fast and get early results, raising your bid can help. But if you're looking for volume and want to scale slowly, reaching more people may be the way. How do you think this can be balanced in real campaigns?
