By default I see that Sandcastle is generating HTML pages and links named with GUIDs. Can somehow this be changed to generate user/SEO friendly names for the pages? Ie. instead of f987d4ff-cabc-10af-86cd-620978605d86.htm I want it create 'namespace.class.method.htm', similar to how the .Net MSDN documentation is generated.
Assuming you're using the Sandcastle Help File Builder, you could try this setting, available in the GUI as "NamingMethod":
<NamingMethod>MemberName</NamingMethod>
Don't know if it exactly fits your needs, but it is an alternative to the GUIDs.
