SEO Career Scope

I'm currently pretty fresh into an SEO job and finding out what parts of the process I enjoy and want to focus on learning more.

I spend alot of time reading posts in here as I see alot of answers from people who are clearly quite knowledgable so recently I have been wonddering what the scope of SEO careers is like? the scope and expectations salary and role wise within agencies, inhouse aswell as wanting to hear from anyone doing freelance work and how that benefits you.

As i said i'm quite fresh to the role but enjoying learning the process and what to know where I could be headed with experience for the future and would love get some insight from anyone who has already walked the path.
