Three Steps to Dumping Autotrader
1) drop to the lowest Autotrader program; be sure your dealer merch page is full and fresh, and that all of your vehicles are accurately commented and appropriately priced
2) set up your classifieds posting with smartpillars, set up database farming through polk and imn or outsell, and be sure your feed is going to every free site and all your calls are tracked
3) fully SEO your home page(s), cut Autotrader and replace with intelligent PPC (like dealer.com's dominator)
