Hi @Siir,
In Moz, you'll find a metric called "Keyword Explorer," which we may say that is similar to the concept of "potential traffic" in Ahrefs.
Keyword Explorer helps you understand how hard it might be to rank for a specific keyword as it considers factors like search volume, competition, and the strength of top-ranking pages.
Also the Monthly Volume which is under Keyword Explorer, will help to estimate a potential traffic for a given keyword.
Hope that helps
