The mobile online advertising revolution has begun. Google announced they are displaying AdWords text and image ads on results pages through their mobile portal. The ads will appear on iPhones, G1s and other mobile devices with full HTML browsing capabilities.
Advertisers will now have the option to include their regular AdWords ads in mobile results, without the need to reformat anything. The ads do have character limits, however. Conveniently, the mobile ads also come with separate performance reporting.
For advertisers, this means that you can now run ads targeted specifically at the mobile consumer. That's good news. But if you want to create a specific, mobile call-to-action you must ensure your pages render properly through a mobile device. That can be a bit more challenging. However, in your account you can make sure all ads point to a desktop landing page.
That brings up another interesting note. As an AdWords advertiser, you are automatically enrolled to display your ads on iPhones, G1s and other devices. Some may want to opt out of this - the mobile space (and the mobile surfer) might not be the best avenue for your advertising spend. You will need to change the setting in your account to opt out.
In the grand scheme of things, everything points to a mobile advertising revolution - forcing advertisers and businesses to think beyond the desktop, ready or not.
