Just to add to our original question. It seems pretty clear that device detection is accomplished by user agent detection. Under our original plan to redirect visitors on mobiles to a new URL which carries the mobile version of the page, how should that redirection be accomplished in a search engine compatible fashion? What type of redirection should be used?

I suspect we'll need to continue with our plan to redirect to a different URL for now, but am concerned that this needs to happen in a way which won't harm our SEO.

many thanks in advance for any help with this ....

Thanks Leslie, interesting and useful considerations.

Hi,

We have a mobile website using a sub-directory domain.com/m/whatever-page/. Our mobile is completely separate site from desktop version.

What's the best way to handle the redirection from mobile visitors and those that are searching from mobile and see desktop version in the search result?

Appreciate anyone's expert advise.

Thanks,
Willy
