We're on Google. I first tried "
site:intosanctuary.com" with 16,700 results, so we're obviously indexed. Then I tried "
old school new school fool school" and we're the sixth result on the first page. The reason why? Because it's something unique to this site. If we want to be indexed for anything proper, then the content has to be here first. Yeah there is a bunch of drivel, but there's even more drivel about the drivel, and less unique content that would bring someone here.
"Totse" or "free speech forum" will probably not yield much because we're not optimized for those terms. A home landing page would help with that. So would just using those terms in our regular threads, besides the "we don't have free speech anymore" garbage. It doesn't look like we can create thread tags, which would help. Not sure about any other site metatags.
Advertising is one thing, having something to advertise is another.
