Even with the first Android device set to launch in a matter of days, Google (NSDQ: GOOG) still has the iPhone and the inherent opportunities it presents high on its mind. The company has been meeting with ad agencies recently to show off different ways to integrate advertising into searches conducted on the phone, AdWeek reports. Google is working to give advertisers the ability to integrate iPhone ad groups into their regular search campaign. The idea is to give ad agencies an opportunity to create iPhone-specific ads that might draw in more interest than ads simply repurposed from online ads created primarily for PCs. For example, companies could place ads that wold allow users to click to call. If implemented, this would be the first time Google has allowed advertisers to make messages specific to mobile searches, however advertisers already have the option of running mobile-specific campaigns on WAP sites.
