News Release Details

SEATTLE, WA - October 1, 2008

Among national advertisers there is significant interest in local online advertising, according to a new study conducted by Sterling Market Intelligence and commissioned by Marchex, Inc., a local search and advertising company. Nearly half of the national advertisers surveyed are currently pursuing local online advertising, and more than 40% are dedicating at least a quarter of their online marketing budget to local targeting. However, their utilization of local online advertising is impeded by confusion about the best tactics and traffic sources to use, and how to effectively measure the results and return on investment (ROI).

"The data shows that national advertisers clearly understand the Internet drives in-store sales and they've begun to integrate local into their marketing mix," said Greg Sterling, Principal of Sterling Market Intelligence. "However, they're all over the map in terms of traffic sources and success metrics; there's a general absence of consistent tactics and understanding of best practices for local."

Key insights from the study include:

• Almost half of survey respondents report that at least 25% of their in-store sales were driven by online marketing
• More than half of respondents are using different messaging or tactics for different geographic or local markets
• Only 10% of respondents are targeting down to the DMA, city or ZIP code level

In a free Webinar titled "Local Online Advertising: Strategies and Tactics Every Company Should Know," scheduled to take place today at 11:00 a.m. PDT through Search Marketing Now (http://searchmarketingnow.com/webcasts/wc081001), Sterling will discuss his findings as well as present case study data reflecting success stories. Afterwards, Ed O'Keefe, VP of Performance Marketplaces at Marchex, will provide best practices and data-driven tactics that advertisers can use to succeed in online local advertising.

"National advertisers are clearly trying to leverage local online advertising to increase local leads and drive sales, but this study shows they're having a tough time figuring out what's working," said O'Keefe. "The good news is that there are techniques and products available, such as business profile pages and call-tracking, to help advertisers drive local leads online and track effectiveness of their local online advertising efforts."

Best practices O'Keefe will cover in the Webinar include

• The importance of diversifying traffic sources beyond paid search and how to manage them
• How to use landing pages to drive leads to specific locations and markets
• How to track and analyze all consumer actions - including calls, emails, form submissions, map prints and coupons - resulting from local online advertising efforts including to determine results and ROI
• How to most effectively tailor ads to local markets and use local call tracking numbers to measure and help generate more calls
