On my site you can do a search for a an artist, this gives a URL of the form
http://example.com/artistid, this goes to my application server if the page has never been requested it then creates it, uploads it to Amazon S3 and redirects to
http://artist.example.com/artistid, if already exists it then immediately redirects to
So my question is how does this fit in with SEO and sitemaps. In Google Webmaster Tools each sub domain seems to be treated separately I cant see anything to tied them together but should I be submitting urls of the form
http://example.com/artistid (which will just resolve to redirects) or
http://artist.example.com/artistid (but I have to make sure the page has already been created if I do it this way). Or should I submit to both ?
