Just like the Rank Ranger, SEMrush, MozCast, et al. trackers. Ahrefs is my go-to SEO tool and I find the UI to be the most intuitive and the data to be the most balanced between comprehensiveness and reliability. It would be very useful to have a SERP volatility tracker on Ahrefs, and especially to be able to view volatility as it pertains to your domains/rank tracking projects. The SEMrush Sensor is the main thing I use SEMrush for these days, and especially as it integrates my keyword tracking projects in the Sensor report, I also maintain a separate keyword tracking project there. But with my preference for Ahrefs, it would be great to have those features available here! Thanks
