If you're Googling "what is a shallot," it means you don't know much about cooking and are trying to learn more. Seems like the perfect target market for an online cooking class.
I agree with GP though, if you don't know what a shallot is, it's not likely you have sufficient interest to pay money to learn about cooking.
Obviously it's regional, but from my UK perspective shallots are not exotic.
I'm not aware that they even suffer from multiple names as do spring/salad/green onions/scallions. Echalions of course, but that's a subcategory.
If shallots are unfamiliar, again, UK, you've spent little time even in supermarket vegetable aisles or restaurants and, surely, are therefore unlikely to actually part with cash a cooking class?
Absolutely not. I am willing to bet that 90%+ of queries are about the confusion between a shallot and an onion. Nothing to do with the desire to learn how to cook.
