Best all rounder SEO tool?

Hi guys, I was wondering if anyone has some recommendations for a decent all round SEO tool? As with everything there’s lots of articles online about it with varying degrees of subjectivity, but I thought who better to ask than the people who use it everyday? I’m mostly looking to use it to - Track rankings positions - Audit our pages - Identify opportunities for growth Some considering factors - Ideally allows to manage multiple sites - Based in UK if that matters - We’re an e-com company Thanks!
