There’s an interesting report in Mobile Marketer about what domain name you should use for your mobile site.

Mobile Web publishers must deploy their sites across multiple domain standards to attract the largest audience, according to Ground Truth.

The company said that lack of standardization around mobile Web conventions presents hurdles for mobile publishers. Instead of opting for one, publishers should launch their sites across all the various mobile Web domains: “m.,” “wap.,” “.mobile” and “.mobi.”

[...] In the week ending July 4, Ground Truth measured 5.01 billion page views that included requests to 1,555,630 unique domains.

The data shows that 18,934 (1.2 percent) of those measured domains and sub-domains were mobile-centric, such as “m.,” “wap.” and “.mobi,” but 17.3 percent of total page views were served from those domains.

The remaining pages were served from domains without a mobile-specific domain, such as “www.” sites.  Some of these sites are mobile-aware, such as http://www.google.com and http://www.facebook.com.

Of the mobile-centric domains, the prefix “m.” and the “.mobi” suffix appear about equally, but sites using the “m.” prefix serve 21 times more pages than “.mobi” domains, Ground Truth reports.

Following in popularity, by number of sub-domains, are the “mobile.” prefix and legacy “wap.” prefix.

Google recommends that you use a subdomain of your current domain (e.g. m.myname.com) rather than .mobi.

Discover Anywhere Mobile recommends that you use m.myname.com, but also that you redirect all other possible domains (myname.mobi and so on) to your primary domain. This recommendation (and much more) is available on our whitepaper on .mobi Tourism as seen in our Resources section.
