Do you have a business that would appeal to travelers or business people on the move? You should consider advertising through Google’s mobile phone advertising model. You can actually run your PPC ads in front of mobile users and there are two ways to do it. You can have your click-throughs land on your mobile website or you can make your ads pay per call.

To make the first option work you actually need a website that is geared toward mobile users. You can actually take your existing site and modify it for that use. Then start running your advertising.

For the second option, you don’t even need a website. You just need a phone. And you can run mobile ads that allow clickers to call you directly from the mobile phone. Google has that capable, but so do a few other service providers such as Superpages, which pioneered the capability.

Mobile advertising is a new and effective way to reach a specific target audience that might be in your scope.

This is the best article I’ve seen on Microsoft’s desire to own Yahoo yet. The reason I think it’s significant, and relevant, is because it addresses the need to acquire additional search traffic in two key areas: Local and Mobile.

In case you aren’t paying attention, local and mobile search are two of the fastest growing areas of search right now. Online advertising depends a great deal on the growth of these two key areas. In fact, if it weren’t for search then online advertising would not even be an industry. Advertisers are there to capture the search market. After all, that’s where the people are.

The author points out, correctly, that search and advertising go hand in hand. To dominate one, you must dominate the other. The reason Google is the leading advertising provider online right now is because Google owns the search market. Microsoft knows this. That’s why an acquisition of a large property like Yahoo is so important to them.

The fact is, and I think most people watching the search industry right now know this, if Microsoft does not acquire Yahoo then any chance that it ever had to compete with Google in the area of search or advertising will be gone. But I like the article for another reason as well. The author compares the local and mobile search products of Google, Yahoo, and Microsoft in order to show how they fare right now. It’s the two areas of search that have no real dominant player - there is still a competitive playing field. And it’s growing, which means that future success in online search and advertising will depend a lot on these two key growing areas. Maybe Microsoft is thinking about that and maybe that’s why Yahoo is so attractive to them. And maybe Yahoo knows it and that’s why they are playing coy. The question now is, now what?
