I once sold a $5,000 hot tub on Amazon.
Because of a book review I posted.
That had nothing to do with hot tubs.
And I don't sell hot tubs.
You can practice marketing with affiliate marketing. Amazon and Clickbank are simplest to get started.
All you need is a basic website. And then sign-up for an account on Amazon or Clickbank.
Then you can practice driving traffic to that website.
I wouldn't recommend SEO. Because you will want to show quicker results and SEO often takes several months to see results.
But you could practice driving traffic to the blog using social media. Or even in-person.
This would give you practical experience in the important parts of marketing:
1 - Researching and choosing a market
2 - Finding out how to reach that market
3 - What messages that market responds to
You might even make a few dollars on top of it :).
