The data in Ahrefs is only as good as the tools it's paired with. Whether it's search traffic, backlinks, rankings, or social media likes, the information in Ahrefs is excellent. I do enjoy its Site Audit Feature: I think Ahrefs' site audit feature is one of the best out there. It even compares favorably to SEMrush, in fact. Also has a really good keyword research tool to find keyword ideas and you can even see data for PPC campaigns on Ahrefs.
