La solución de medición ______ se reporta cuando las campañas están activas y se actualizan diariamente, lo que permite a los anunciantes realizar optimizaciones a la mitad del periodo de publicidad.

Omnichannel metrics provide daily updates on campaign performance while campaigns are active, enabling advertisers to make real-time optimizations. This is crucial for agile campaign management and maximizing return on ad spend. Amazon Brand Lift measures the impact of advertising on brand perception and is typically reported after a campaign, not daily during its run. Amazon Attribution tracks the effectiveness of non-Amazon ad channels in driving sales on Amazon, but it's a measurement solution for external traffic, not the primary real-time optimization tool for active Amazon ad campaigns.
