News Release Details

SEATTLE - Mar. 8, 2010

Marchex, Inc. (NASDAQ: MCHX), a leading performance marketing company, today announced that Leigh McMillan, SVP and GM for Marchex Call Analytics, will lead a Webinar titled, "Call Tracking: Great Way to Boost Conversions" on March 23, 2010 at 11 a.m. PT. Sponsored by AdvertisingAge, the event is free and open to the public.

While tracking online activities through Web analytics has become an integral part of most marketing programs, using call analytics to capture online-to-offline conversion is often overlooked. Yet having the ability to measure the source of a phone call can dramatically increase the overall ROI of a campaign—as well as clearly display a campaign's true performance.

In addition to discussing how marketers can use call analytics to capture offline conversions and improve overall conversion rates, McMillan will answer the following questions:

• Who should use call analytics?
• What kind of data is valuable to track?
• What are the keys to success for a call analytics program?
• What should you look for in a call analytics provider?

Stacy Williams, president and founder of Prominent Placement, will also share detailed case studies to illustrate how call analytics has impacted her agency, as well as her clients' campaigns. Prominent Placement is a full-service Atlanta-based SEM firm.
