It might not mean much to most recruiters, since most of them aren't technical themselves. But as someone who hires, and is technical, you would absolutely have an advantage if I were hiring for a marketing position (honestly, if I were, I'd reach out to you now). It's a no-brainer for me - especially for traditionally non-technical positions like marketing, where technical skills beyond MS Office are rare.

I think the bias against "University of Phoenix" type degrees doesn't really apply to online courses like Stanford's. Everybody knows that they're money-making schemes - so it frankly calls your judgment into question if you do it. I would wonder - why did this person choose to spend time and money on a University of Phoenix degree, rather than just take the free Stanford courses and learn on their own?

The issue with the Stanford online courses is that it's common knowledge that not many people stick it through to the end / pay attention. So having it on your resume would get my attention, but I would need to verify that you actually absorbed the knowledge. Once that concern is addressed though, you absolutely have an advantage in my book.
