Via Reuters, Marchex Inc. is introducing 100,000 websites featuring local services. Sites such as denverautorepair.com and newyorkdoctors.com are just a few of the properties where Marchex will provide users with access to more than 15 million of its nationwide business listings.

Marchex has existing partnerships with AT&T Inc. and is affiliated currently with YellowPages.com, through which they sell advertising that appears on the Marchex local online advertising network.

Marchex hopes to capitalize on organic search traffic but the competition is sure to be tight. If they can manage to secure sufficient traffic, Marchex will definitely be a place to spend a few advertising dollars in the future. WM will keep you posted on their progress.
