Investors and online advertising experts may want to consider for a moment what, exactly, has contributed to Google’s stupendous financial success (current market cap: $180 billion).  Now consider this: Google thinks mobile ad rates might surpass what’s come to be deemed the industry standard.

According to Reuters, Vic Gundotra, a vice president of engineering at Google, announced during a webcast, "We hope and believe that there’s even a chance that we could exceed desktop in the future."

Of course, this isn’t the first time someone representing the search giant has spoken highly of the mobile market; CEO Eric Schmidt and CFO Patrick Pichette, among others, have emphasized its importance before.  Earlier this month, a VP of advertising even claimed that desktops will be irrelevant in three years’ time.

Still, Gundotra’s comment may signify just how much Google is betting on the success of Android and mobile advertising, and how seriously it will take threats posed by Apple, Microsoft, and other companies.

Here’s one last interesting tidbit: with regards to China, Pichette said during the same webcast that the country’s "another great market in which Android should flourish."
