I'd say that there's a whole lot of effort that goes into marketing, retention, and conversion (as opposed to visual work). I didn't cover how to drive traffic to a web page; that'd be a great "sister topic" to this one. As an aside: that little link at the bottom of that page has converted better than anything else I've done. ;)
