The Dirty Little Secrets of Search | Long term, gaming Google doesn't help you.

Does the collective wisdom of the Web really say that Penney has the most essential site when it comes to dresses? And bedding? And area rugs? And dozens of other words and phrases?

The New York Times asked an expert in online search, Doug Pierce of Blue Fountain Media in New York, to study this question, as well as Penney’s astoundingly strong search-term performance in recent months. What he found suggests that the digital age’s most mundane act, the Google search, often represents layer upon layer of intrigue. And the intrigue starts in the sprawling, subterranean world of “black hat” optimization, the dark art of raising the profile of a Web site with methods that Google considers tantamount to cheating.

Despite the cowboy outlaw connotations, black-hat services are not illegal, but trafficking in them risks the wrath of Google. The company draws a pretty thick line between techniques it considers deceptive and “white hat” approaches, which are offered by hundreds of consulting firms and are legitimate ways to increase a site’s visibility. Penney’s results were derived from methods on the wrong side of that line, says Mr. Pierce. He described the optimization as the most ambitious attempt to game Google’s search results that he has ever seen.
