Frances, there has been loads of redirect code suggested on TG for switching to a mobile-specific site, so it certainly can do it.

If I have my Xara site with links that a mobile user has to click to access the mobile pages that is not going to rank as high in the SE ratings.

I don't think the article says that specifically.

It's about where there is a redirect for mobile, how that is handled.

Some of the techniques mentioned require server-side programming.

I have a feeling that Google might even might start ranking results according to the device used to do the searching, which would certainly add a new dynamic.

Interesting times.
