There are many different definitions and skill levels of what a Search Marketing Specialist is or does.
It can also depend on where you work - If you work for a large corporation, you might get a job focused on a specific task like email campaigns or social media campaigns, but if you're with a smaller company - you do everything :)
As for schooling that gives you the title "Search Marketing Specialist", I don't know.
I can tell you that the most valuable asset to get a job as a "Search Marketing Specialist" would be actual task/job experience.
Whether you get that by being an apprentice and/or volunteering at a place that does Online Marketing or if it's by building your own online space using digital marketing techniques to "prove your stuff", that "real life" experience will land the job better than that Digital marketing course (I'd choose both of course).
In many cases you start out at the bottom of the pay scale because you haven't prove yourself and you're still learning, don't shy away from that because the experience is priceless and will set you up for success later on.
Never underestimate the path of small beginnings... it often leads to great things!
Good luck with everything!
Search Marketing is a constantly changing field, so ongoing education will become a part of your daily job. I don't think it takes much time to get into the field, but it does take a few years to become good at it and, again, it's constant ongoing learning through experimentation, podcasts and reading.
