When you write mobile are you referring to high-end phones or tablets since most well-constructed sites will render perfectly on 7/8/10" tablets and netbooks.

It may sound stupid but have you checked what your site looks like?

Even though I have dedicated mobile versions for my most popular sites the volume of users is extremely low, of the 19.2% for December users of mobiles and tablets practically all used my desktop sites.

YMMV!
