What tactic can prevent loss of potential ad revenue?

Ensuring enabled ad types are visible on the devices your audience watches on directly prevents loss of potential ad revenue because if ads aren't displayed, they can't be viewed or clicked, meaning no revenue is generated. Setting videos to "unlisted" makes them undiscoverable through search and browse, significantly reducing viewership and thus ad impressions. Selecting a usage policy of "block" prevents monetization entirely for matched content, directly foregoing revenue. While referring to the Video report is good for analysis, it's a reactive measure; it doesn't proactively prevent revenue loss in the same way optimizing ad visibility does.
