A big problem about SEO i found in WebGUI is the problem about the Standard Homepage Asset and the NotFound Asset. Both are parsed in some internal ways, which means that both URLs contain the same content. This is a so called "double content" situation, which makes negative points in the SEO area. So if you set a homepage asset which has the url /home, then you can reach your homepage with / and /home and both show the same content. On not found page it even gets in a bigger scaled problem. WebGUI should make a redirect to the specific asset to make it clean. This would solve all problems on that situation.
