This should have been Ask HN, I suppose. The answer is it depends.<p>If you're outside of the field, looking to break into an entry-level position, and would like to have your hand held the whole time, it possibly does (provided you live in a high-earning country such as USA, Australia, Switzerland, etc.--if you're from rural Africa and you'd take year(s) for you to pay it off, the answer is always no)<p>If all you're looking for is knowledge, possibly widening your horizons or gaining some interesting useful knowledge, the answer is no.<p>My 2c of course.
As a self-taught marketer, I would say it is a better investment to use this money to build your own website and learn the basics from experience. From this experience, you can learn:<p>- How to setup a CMS (e.g. Wordpress)<p>- Keyword Research<p>- Content Marketing<p>- On/off-page SEO<p>- Optimizing for conversion rate<p>- Building and managing a mailing list<p>- Email Marketing<p>Also, being able to tell this story is much more interesting than simply saying: "I have this certificate from Udacity".
