Nearly 30% of traffic comes from a mobile device¹ – is your website optimized for those shoppers?  In this blog post on Auto Dealer People, Ali Amirrezvani shares some great tools for seeing what your website looks like on a mobile device:

GoMo: GoMo was launched by Google in November to help businesses optimize their website for mobile.  Take a look at how your site looks currently on a mobile device using the GoMoMeter, get recommendations for improving it and check out great examples from other businesses.

iPhone4 Simulator: Just as the name implies, iPhone 4 Simulator simulates what your site looks like on an iPhone 4.  The tool is similar to the GoMoMeter but is exclusively for iPhone and illustrates how your site looks in both profile and landscape format.
