Duplicate content issues using a separate .mobi for the mobile version of your site?

Bump for an answer.

There is no such thing as a duplicate content penalty on Google on different websites/domains.

Thanks for clearing that up.

So according to you Webmaster Advertising, I can copy a .com to a .mobi exactly, and the .mobi would stand equal chance of ranking? LOL.

I know from experience of having an identical site to a sponsor I promote that this isn't correct.

Anyone with a clue know the answer pls.

I wouldn't copy them over directly, to much risk and the worst thing to happen wouldn't be your new mobi not ranking, but the worst would be if they decided your mobi, was the authority and removed your main site from results due to dup content.

I have mobile set up for a couple sites but I've used a subdomain and basically just hoped that there isnt an issue displaying the content again, so far there hasn't been. But I haven't copied over a site to a new domain, that just seems to risky for me.

If anything I would rewrite/doctor the text work on the new mobile, so its not duplicate. Also , there is a command or meta to show related pages, I imagine there may be an avenue to include the 'mobile version available here' to show google its supposed to be there.

Just what I was worried about Jdoughs, thanks for your help.
