To know if your push notifications are helping your affiliate sales, there are a few key numbers to check. Start with open rate—this tells you how many people actually saw your message. Then look at click rate, which shows how many clicked your link. Most importantly, track conversions—this is how many people bought or signed up through your affiliate link. If you're running multiple messages, it helps to compare which ones get more results. Unsubscribe rate is also useful, since it shows if you're sending too often or missing what your audience wants. Watching these numbers regularly can help you improve and earn more. What other simple ways have worked for checking push campaign success?
