The web developer we hire for our site never put the rel tags in when they set up our mobile site on m.sitename.com. What they did do, is put links on every page of the site saying essentially, "view mobile site" (on the standard web version) and "view traditional site" on the mobile pages. For whatever reason, they used a tracking link (ie, /?source=mobile) to link back to the main site from the view traditional link.
Google (and presumably other search engines) is now seeing all those pages (the whole site) linked with ?source=mobile as duplicate content. How should the link be set up so real world visitors can choose to move between mobile and traditional views if they want, but the search engines won't see the linked pages as duplicate content? Do we need a no follow tag or something on the links, in addition to setting up those rel canonical and rel alternate tags on the appropriate places?
