This is not going to be the popular opinion but at this point, if your project is not for profit (As I assume most fan-made wikis are), I've found it's best to just ignore Google. Leads from Google are typically not good anyway, especially if what you're trying to build is some type of community.

I understand that Weirdgloop is probably some kind of business, so it makes sense that they would care. And if you care, more power to you, I don't want to discourage anybody. I'm just out here promoting the idea that not everything you do has to be the next big thing. Sometimes it's okay to make a weird project and have only a handful of people care about it.
