We've just released a mobile version of our website.
The system detects the browsers user agent and serves the most relevant version of the website.
The URL's are the same for both mobile and main website.
We added Googlebots mobile user agent, (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html) however using instant preview in GWT, it's not showing the mobile version. Though I switched my user agent in Firefox, to Googlebot Mobile, and the mobile version of the website is displayed.
I'm not even sure, if this is the best practice?
One major concern, is not all pages are available via mobile. If a mobile phone manually visits a page that doesn't support mobile, an error will be shown.
Will Googles mobile user agent try to crawl every page indexed, or will it only crawl pages that are linked via the mobile version?
Are there any other SEO considerations with the mobile version?
Thanks a lot.
