Answers to questions such as how and where ads will run on mobile devices and how landing pages will be served can all be answered on Google’s new Adwords support page. Pages that are not mobile device friendly will not be available for mobile Adwords:
Each ad’s eligibility will be determined by its landing page and only ads with landing pages that can be adapted for viewing on mobile browsers will be shown. You can monitor each ad’s performance via a special performance tracking page within your account called “Performance Data: Search Ads on Google Mobile Search.”
To see how their landing pages will display on mobile phones, advertisers can visit http://google.com/gwt/n. Simply enter the URL for a preview.
Additionally, advertisers who do use Adwords can opt-out of the Google Mobile Adwords program if they like:
You can opt out your eligible search ads from running on Google Mobile Search pages at any time. On the Campaign Summary page, select the link that says ‘View performance data for these ads’ from within the alert message or below the table that contains your campaigns. On the bottom of the page that reads “Performance Data: Search Ads on Google Mobile Search,” click on the link that says ‘Yes, opt me out’ to stop running your search ads.
This is a great way to test and experiment with your ads on the mobile platform, but how many people will take advantage of this free service?
