Additional skills for online marketing?

[SuperPug â™”[Uk]â™”]

So, I'm at university studying for my marketing degree. I know alone the degree is not enough and because I want to go into online marketing, I don't feel there are enough modules on the subject. (A specific course wasnt available). So I was wondering what are some potentially very useful skills and techniques that I could learn and improve on in my own time? I heard that copywriting is quite a good one and reading up on PPC (pay per click). Any skills or knowledge of certain software that marketers here have that they have found to come in very handy?

Thanks for any help. :]
