3. Why adCenter What’s Working for our Clients “The ROAS comparison for June for our biggest client, expressed as revenue per ad dollar spent, is $2.85 for AdWords, $5.53 for Yahoo, and $8.13 for Microsoft adCenter. Needless to say, we’re going to increase our investment in Microsoft adCenter right away.” — David Szetela, President & CEO, Clix Marketing, www.clixmarketing.com “The efficiency gained from Microsoft adCenter allowed Move.com to be more aggressive with its acquisition strategy, resulting in more conversions across the entire campaign.” — Frank Lee, VP, Account Management & Partner Relations, The Search Agency “The campaign has been an overwhelming success. We have seen conversion rates up to two times as high as other major search engines, including Google, all at lower bid prices. At this point, we want to spend as much money with Microsoft adCenter as we can because it simply works as well or better than anything else out there. -- David Rodnitzky, Senior Director of Marketing Adteractive “MSN achieved an excellent rate of return on the amount we spent. Register.com looks forward to growing our paid search campaign with MSN as the engine expands.” -- Craig Cooperman, Director, Advertising & Partner Marketing at Register.com.
