In the auto business the Internet has become the primary means through which dealers market their businesses. Consumers use the Internet to research vehicles, dealers, and prices before ever stepping into a dealership. The amount of information buyers can obtain from search engine queries is exponential and gives them an advantage when it comes time to buy. As online consumer networks continue to grow so too does the need for car dealer search engine marketing? SEM enables dealers to drive better quality and greater quantities of online traffic to their sites, resulting in greater visibility, higher conversion ratios, and increased profits. As with all good things SEM comes with a downside. Due to the vast nature and complexity of the Internet, search engine marketing is extremely difficult, multifaceted, and expansive. Therefore, the best way for car dealers to achieve their online marketing goals is by employing trained online marketing professionals.
