There are no standard mobile website naming conventions. Following is an example of a few naming strategies that have become common over time. You may also find that some popular websites use more than one of these:
m.domain.tld—For example, m.myspace.com and m.boston.com.
mobile.domain.tld—For example, mobile.yahoo.com and mobile.myspace.com.
domain.tld/mobile—For example, boston.com/mobile.
domain.mobi, a top-level domain (TLD) managed by the mTLD global registry. For example, cantoni.mobi.
