The Hermansen brothers

Dave Hermansen did not own a bird or a cage when he bought bird-cage.com, an online store, for $1,800 three years ago. He simply saw a Web site that was “very, very poorly done,” and begged the owners to sell it to him. He then redesigned the site, added advertising and drove up traffic. Last December, he sold it for $173,000.

Hermansen, 30, is among the latest wave of entrepreneurs who, like the day traders and real estate investors before them, are looking to make a lot of money without much effort.

They use little more than home computers and free software to buy Web sites that appeal to a small and specific niche. Then they fix up the sites with hopes of reselling them for far more than they paid…

While there is no data on how many people flip Web sites, the number of sites sold on eBay has doubled over the last three months, the company said. At SitePoint’s marketplace, a similar forum where users can auction off Web sites, sales have quadrupled in the last year.

Instead of selling goods and services, analysts said most flippers are looking into the easiest way to make a quick profit, by tapping into specialized advertising.
