By now, you may be curious about what Marchex does. The company owns a few contextual pay-per-click marketing outfits, including IndustryBrains and Enhance Interactive. However, the part of Marchex that appeals to me most is the direct-navigation business.
Even though direct navigation made up just a third of the company's revenues, that part of the company's business has the most potential. Of the roughly 200,000 domain names Marchex owns, 74,000 happen to be ZIP code-dot-com (and in some cases dot-net) domains that cover 96% of the country's five-digit postal codes. There's not a whole lot of content there, but if you click on, say, 90210.com, you will be treated to basic information and a ton of ads from Yahoo! (Nasdaq: YHOO - News). Every interested click on a Yahoo! sponsor's text ad results in Marchex receiving the lion's share of the ad revenue.
