Mobile site with same content as main site, is there a risk?
Now, this may seem like a bit of a noddy question to some of you but maybe it's not.
If I have a normal website within which is a directory "mobile" which holds the pages optimized for the mobile web and I submit a sitemap for each of them independently, will Google see that as duplicate content as they draw their content from the same database?
I would assume that, as they're on the same domain, it wouldn't?
If they're on different URLs I could potentially see issues... You may be able to set it in the Google Webmaster Tools that it's a mobile site or if you put it on .mobi it may know that already.
Beyond that, if it's the same URL and the content sent to the browser is identical and just formatted differently I don't see how you could have any issues.
Google does have a "mobile browser" crawler too, I do believe and I don't see why they would penalize you for content found via the mobile browser crawler that was similar or identical to content found with the regular crawler.
