Looking to do some self-paced learning in the industry I'm currently in (digital marketing) to further my career.

Seriously considering the digital marketing certificate offered through Illinois university and Coursera because of a couple reasons:

1 - One of the instructors is head of industry at Google (knows what he's talking about)

2 - No physical college/uni near me offers any useful programs in Digital Marketing. I tried attending a few courses but the information was very basic and something I'm far past already through freelance work over the years.

So my question is, do these certificates hold any value or validity, and has anyone taken a coursera course and felt they got something useful out of it?
