In this interview from SMX Advanced 2009, Rand talks to mobile search guru, Cindy Krum, of Rank-Mobile.

Cindy starts off by noting the excellent SEO Audits panel at SMX Advanced, saying it's one of the best sessions she's seen. Fortunately if you missed it there are lots of great writeups on the session (Lisa Barone's recap has lots of good links in it).

The discussion then moves to CIndy's true area of expertise, mobile search. In particular she reviews some of the things she discussed in her presentation on Adwords for Mobile, including why you should treat the iPhone as a separate ad group, whether you should consider traditional WAP browsers, the difficulties of monetizing mobile ads, and more.

Cindy's a true expert on this stuff, so if you play in the mobile space or you're just curious about it, this interview is definitely for you. For more, you can read Cindy's blog, or follow her on Twitter (@suzzicks)
