Information Week did an interview with David Harper, founder of Winksite, and one of the organizers of NYC’s Mobile Monday regarding mobile search engine optimization.

There’s some great tips in the interviews, especially for people who are just starting to set up their mobile sites.

But there’s an interesting trend that may push back against SEOs being effective. Check out the graphic on Yahoo Mobile’s site.

Search engines are taking it upon themselves to get the user to information without leaving the search site itself. If this continues, more and more information could be harvested from sites and presented in a search portal environment without the user ever visiting the original mobile site.

I think you have a lot to worry about now if your mobile site presents basic information like weather or other obvious basic info. You don’t need to leave Yahoo or Google mobile search to get that stuff.

If your mobile site is actually a service, like a mobile social network, you’re probably safe for a while, since search engines won’t be able to offer a quick replacement for your service.

If you’re just some random bit of information, like “Generic drug alternative to Ambien” - you need to worry where the search engines will draw the line. I’m sure all of them want to be able to pop up the succinct answer to the user without linking out, but they probably can’t do that effectively now. So how long until you suddenly see your mobile traffic drop off because they mined your data?
