There is already some data marked as "Ahrefs metrics" in Site audit's data explorer. It would be wonderful if you could add the keyword specific data also to the data explorer.
This would open a myriad of possibilities. Such as identifying ranking issues caused by technical problems, cannibalization, lack of quality content etc etc.
You already have this keyword data available in the Site explorer (list of specific keywords and the amount of ranking keywords per page). You really should integrate this to Site audit tool.
Bonus idea: there should be also a way to integrate data from Ahrefs Rank Tracker to Site audit. Integrating these tools / views would be some next level SEO!
