To keep an eye on ad viewability in real time, you can use tracking tools provided by your ad network or third-party platforms. These tools show how often your ads are actually seen, not just loaded. For example, some platforms offer real-time dashboards where you can track impressions, viewable rates, and engagement. This helps you know if your ads are appearing in the right spots on the screen and if users are paying attention. If the viewability numbers drop, it could mean your ads are being placed too low on the page or on sites with less active users. Do you think real-time tracking has made a difference in how you run your campaigns?
