CAMBRIDGE, Mass.--ATG (Art Technology Group, Inc., NASDAQ: ARTG), the leading e-commerce platform and optimization services provider, today announced that Equipment Trader, the largest online classified advertising marketplace for equipment buyers and sellers, has introduced enhanced calling capabilities for its advertisers based on ATG’s eStara Click to Call service.

“EquipmentTraderOnline.com has just re-launched with improved lead generation and dealer inventory management tools,” said Nick Petsos, brand manager of Equipment Trader. “eStara Click to Call is a key feature in the Web site redesign that proactively and intelligently engages consumers at strategic points throughout the sales process.”

Equipment Trader allows both dealers and independent owners to easily access more than 1 million active equipment buyers each month who are interested in researching and purchasing new and used equipment online. With the Web serving as an extension of the brand, delivering a positive online experience can make the difference between a browser and a buyer. Click to Call creates a continuity of experience for consumers as they transition from the Web to the phone from any directory listing for immediate contact with the seller.

A division of the classified advertising, publishing and web and data services company, Dominion Enterprises, Equipment Trader has implemented eStara Click to Call to give shoppers the opportunity to immediately speak to a dealer with a click of a mouse. In turn, dealers receive real-time information about the buyers, including data detailing at which point during the transaction the buyer decided to make the call. This information gives dealers insights into a potential customer’s needs, prompting a more hands-on conversation.

“Media companies like Dominion Enterprises are looking to differentiate themselves in a highly competitive cross channel industry,” said Shari Solis, vice president, media at eStara. “eStara Click to Call delivers real-time personalized service to increase conversions, reduce site abandonment, collapse call handling times and make the online experience more relevant for potential equipment buyers.”
