Off the top of my head, I liked how it:
• tied together crawling, indexation, rankings (powered by GSC data), and conversions (powered by GA4).
• was super fast. Like REALLY really fast.
• allowed you to build an endless array of segments of pages / queries / GA4 behaviors to track.
• Ux was strong. Each view was simple. This allowed the user to “keep the main thing the main thing” in each view
• was able to show how important internal linking was towards getting content indexed.
