I've been experimenting with using Wikidot to attain quick indexing on the search engines, and the results have been amazing. It seems that the way a wiki is set up is just what the search engines are looking for, it gives a way for someone to easily provide quality content in a way that the visitor can find quickly.
A wiki is much like a blog, which also gets good search engine love, but it's organized differently. Typically a blog shows recent posts from top down, most recent on the top, down the page to a limit set by the blogger, and the archives reachable on the side by title.
To me, that's not a good way to organize a site. A site should be organized by theme. Sure, blog posts can be categorized, but typically otherwise it's by date.
With a wiki, you can organize in a more user friendly fashion. But I digress.
I've been playing with wikis of different types for a few months now. I wanted one where the pages were search engine friendly, in other words didn't have the dreaded question marks, and that could be secured from unwanted updated by outsiders.
Since a wiki traditionally allows others to make changes, I wanted one where I could allow people to add to my wiki if it made sense, but without giving them the ability to modify pages that they didn't originally create. Wikidot easily provides this facility.
Along the way, I found that my wiki pages are quickly picked up by the search engines, and often attain great rankings, causing good traffic to come to it. And, since it can be organized so efficiently, visitors stay and browse around to their heart's content. Another good thing, I'd say.
