As important as search marketing is to your business today, it will be even more important soon, if for no other reason than more people will be searching more often. Not only will people without computers today gain access to computers over time, but people who already have computers will be connected to the network more frequently than they are now, using portable devices such as cell phones, PDAs, MP3 players, and many more.

One of the things that will drive search usage from these devices is what designers call the "form factor"—how large the device is. You can imagine that browsing and navigating the large Web pages that exist today will never work as well on a cell phone's tiny screen as it does on a computer monitor. And while some researchers believe that information can be projected in front of your eye or on the table at Starbucks, that's farther away than people using the small screens that we already have. Those small screens just need constant connection to a network to become the search platform of tomorrow, and everyone from cell phone providers to wireless computer networks are figuring out how to make the network pervasive at a low cost. So, one simple reason that search will explode in the next few years is that mobile users will get connected and no way of accessing information will work better than search.

I came across a neat demo that gets us one step closer to more ubiquitous search—one that uses voice recognition to empower mobile users with the kind of information power that today you need to be seated in front of a computer to wield. XM Satellite Radio teamed up with VoiceBox to show how voice recognition can be paired with satellite radio to provide easy information access while driving—hands free and eyes free.

Imagine how this technology could work with a next-generation search engine that could answer questions, rather than just listing Web pages. Ask a question, get an answer—just as naturally as asking another person. Now it will be some time before search technology works as smoothly as it looks in that demo—the demo is confined to some well-understood subjects, rather than an unconstrained search in Google—but this demo shows you what will become possible.
