The job of a web analyst sounds fairly complicated. I maintain a website for myself, and I can barely understand the information generated by my user panel on traffic and how people found my site. I can't imagine having to compile a report on something like that and present to a bunch of people.
I guess that's why companies employ web analysts though. It's much better to have an expert to keep your website secure and go through the system-generated reports rather than making it a secondary part of someone else's job.
