Site Speed: the speed of your site was one of the biggest factors to ranking. For a dealer, have you gone through and made sure your images are compressed and sized properly? Your images should be around 150 kb. One of the biggest factors to site speed slowdown is large image size.
One of the other major factors for ranking in voice search is the idea of " Simple, easy-to-read content may help with voice search SEO". You need to be presenting content on your website that provides simple answers to the shoppers questions. If you want to increase traffic for your service department, you don't want content around certified service, but content that answers the 5 most important reasons someone should get their oil changed at a dealership.
