Have Content Ready: Google recommends having 10-20 posts on your Google+ business page before you really start promoting it. Recent posts is one of the things they use to judge the quality of your page, so having it full of content once people start visiting it will help.
Promote Your Page: Add a Google+ button everywhere you promote your other social media accounts. Allow your website visitors to +1 your inventory and dealership from your site.
Incorporate your +1’s into AdWords: Google will pull your +1 count into your AdWords campaigns if you link them. Within your AdWords account, click the Ad Extensions tab. Select “Social Extensions” from the “View” menu, and enter the URL to your Google+ page. Talk to your dealer website provider or PPC vendor to get more information.
Make sure your dealership’s Google+ page is optimized and ready for the combination of Google Places into Google Plus Local.
