How to Target Only Desktop in Adwords Express Platform[ Edited ]
Re: How to Target Only Desktop in Adwords Express Platform
In AdWords Express, it's not possible to choose only one of the available ad delivery options. The program automatically serves ads on all devices.
For what it's worth, AdWords Express does eventually shift your ad serving to the platform(s) that work best for your ads.
