Relevance is a search engine's holy grail. People want results that are closely connected to their queries.

The number of small businesses in the United States totals about 25 million. Because most of these have a local trading territory, relatively few advertise online. Online advertising reaches the masses of the Internet world, whether they are local or not.

Traditional local media are adding local search capabilities to their sites so they can share in the local search traffic and ad revenues in the local markets they serve.

In direct navigation, users type exactly what they are looking for in the browser's web address field. This could be the exact domain name or web address. Millions of people do this, emphasizing the need for on- and off-line marketing and branding.

Traditional horizontal search engines cannot always identify the target audience, niche or vertical industry of a page or site. Vertical search engines address this issue by the nature of their design. They identify sites according to more specific criteria and sometimes even by human input.

I ended up buying business.com for $150,000 because I wanted to make it a magazine. It would have been a 'Time'-type magazine: how to do business on the Internet. And I was offered a lot of money for that domain. I played two buyers against each other.

Direct navigation traffic is by far the most highly targeted form of web traffic available.
