Systems and methods for pulsing and controlling quality of content are provided. An automated QC system that automatically monitors (e.g., pulses) content for any changes by third-party servers and subsequently deactivates problematic content may improve user experience in relation to viewing content and enhance revenue gains for the content provider. For example, a confidence tool may identify problematic changes to the content via a pulsing mechanism, in which content is identified for deactivation until changes to the content meet the specification of the content presentation services. Active (e.g., live) or in-flight (e.g., scheduled to be live) content may continue being pulsed for any modifications unless it has been deactivated
