Frequency caps are used to control how often the same user sees your ad. If you set a low cap, like once per user, your budget will spread across more users and may last longer. But if you allow higher caps, like 5 or more, your ad can show more often to the same users, and your budget might run out quickly. That’s because it keeps spending on the same people instead of finding new ones. Some people prefer higher caps for brand recall, while others go for lower caps to avoid wasting money. What kind of cap do you think is better for pop ads in affiliate campaigns?
