AS we become increasingly dependent on the Internet, we need to be increasingly concerned about how it is regulated. The Federal Communications Commission has proposed “network neutrality” rules, which would prohibit Internet service providers from discriminating against or charging premiums for certain services or applications on the Web. The commission is correct that ensuring equal access to the infrastructure of the Internet is vital, but it errs in directing its regulations only at service providers like AT&T and Comcast.

Today, search engines like Google, Yahoo and Microsoft’s new Bing have become the Internet’s gatekeepers, and the crucial role they play in directing users to Web sites means they are now as essential a component of its infrastructure as the physical network itself. The F.C.C. needs to look beyond network neutrality and include “search neutrality”: the principle that search engines should have no editorial policies other than that their results be comprehensive, impartial and based solely on relevance.

The need for search neutrality is particularly pressing because so much market power lies in the hands of one company: Google. With 71 percent of the United States search market (and 90 percent in Britain), Google’s dominance of both search and search advertising gives it overwhelming control. Google’s revenues exceeded $21 billion last year, but this pales next to the hundreds of billions of dollars of other companies’ revenues that Google controls indirectly through its search results and sponsored links.

One way that Google exploits this control is by imposing covert “penalties” that can strike legitimate and useful Web sites, removing them entirely from its search results or placing them so far down the rankings that they will in all likelihood never be found. For three years, my company’s vertical search and price-comparison site, Foundem, was effectively “disappeared” from the Internet in this way.
