Google, in an effort to help small business ensure they have an effective mobile website, has launched "GoMo".  This website (http://www.howtogomo.com) lets users learn about why having a quality mobile site is important, test how your site looks in its mobile version, and find resources to help if your mobile site isn't quite up to par.

I really like the option to see how your current site looks in mobile.  From the homepage, click "See How Your Current Site Looks in Mobile", then "Test Your Site".  Enter the URL of your dealership website to see how mobile users will see it.  After answering a couple of questions about what you see, you'll get a report card of sorts that focuses on four potential mobile website hangups: Loading Speed, Images, Text, and Navigation.

The DealerOn auto dealer website I tested scored a 4 out of 4.  According to the site, the site I tested showed:

Loading Speed:  0.404 seconds.  The recommended loading time is 5 seconds.

Images: Images appeared properly

Text: Text is visible without pinching or zooming on the phone screen

Navigation: All links and buttons are thumb friendly

Check your dealership website to see how well it scores.  If you're not getting a Pass in each category, you need to talk to your mobile website provider to find out what can be done.
