¿Cuáles de las siguientes estadísticas están incluidas en el reporte de términos de búsqueda principales?

The "Tasa de conversiones" (Conversion Rate) is a key metric included in the Search Term Impression Share report. This report helps advertisers understand the performance of search terms that trigger their ads, and conversion rate is crucial for evaluating the effectiveness of those terms in driving sales. "Unidades pedidas" (Units Ordered) is also typically available in performance reports, but the question specifically asks about the Search Term Impression Share report, which focuses on search term performance metrics. "Conteo de clientes repetidos" (Repeat Customer Count) is a customer-centric metric that is generally found in broader customer insights or sales reports, not typically within a search term-specific performance report like the Search Term Impression Share report.
