How do people even find my site online?

You think there is a trick you have not learned yet. There is not. A search engine works like a friend does: it finds what matches the words someone typed, and it trusts what others already point to. Your team wants to skip the plain work — writing in the words your reader actually uses, earning a mention from someone they trust — and still land on the first page. That wish is the real obstacle. Not your ignorance of some hidden system. Work through this together, not alone. One person guessing misses half the words real customers type. Four people comparing notes will find them faster than any guide could show you.
