Google announced a couple of new targeting options for mobile advertisers today: WiFi targeting, and targeting by mobile operating system version.

“To reach users when you know they’ll have a high speed connection, you’ll now be able to target your campaigns to mobile users specifically on a WiFi connection,” says Google Mobile Ads product manager Morgan Hallmon. “If you’re currently targeting users on specific mobile carriers, you can now target users on WiFi connections too, and expand your reach. This is also useful if your campaign or landing page has high bandwidth content, like videos that you’d like mobile users to access.”

“You can already target mobile users by their operating system platform,” adds Hallmon. “For example, you can specify whether you would like to reach Android, iOS or WebOS devices with your ads. We’re now giving you even more granular targeting options if your application or service is only applicable to particular platform versions, such as ‘iOS version 4.0 and above’.”

The new targeting options can be found under Campaign Settings.
