Here’s another hypothesis, this one for the conspiracy-minded. Last year, Advertising Age obtained a Google document that listed some of its largest advertisers, including AT&T, eBay and yes, J. C. Penney. The company, this document said, spent $2.46 million a month on paid Google search ads — the kind you see next to organic results.

Is it possible that Google was willing to countenance an extensive black-hat campaign because it helped one of its larger advertisers? It’s the sort of question that European Union officials are now studying in an investigation of possible antitrust abuses by Google.

Investigators have been asking advertisers in Europe questions like this: “Please explain whether and, if yes, to what extent your advertising spending with Google has ever had an influence on your ranking in Google’s natural search.” And: “Has Google ever mentioned to you that increasing your advertising spending could improve your ranking in Google’s natural search?”

Asked if Penney received any breaks because of the money it has spent on ads, Mr. Cutts said, “I’ll give a categorical denial.” He then made an impassioned case for Google’s commitment to separating the money side of the business from the search side. The former has zero influence on the latter, he said.

“If you asked me for the names of five people in advertising engineering, I don’t think I could give you the names,” he said. “There is a very long history at Google of saying ‘We are not going to worry about short-term revenue.’ ” He added: “We rely on the trust of our users. We realize the responsibility that we have to our users.”

He noted, too, that before The Times presented evidence of the paid links to JCPenney.com, Google had just begun to roll out an algorithm change that had a negative effect on Penney’s search results. (The tweak affected “how we trust links,” Mr. Cutts said, declining to elaborate.)

True, JCPenney.com’s showing in Google searches had declined slightly by Feb. 8, as the algorithm change began to take effect. In “comforter sets,” Penney went from No. 1 to No. 7. In “sweater dresses,” from No. 1 to No. 10.

But the real damage to Penney’s results began when Google started that “manual action.” The decline can be charted: On Feb. 1, the average Penney position for 59 search terms was 1.3.

On Feb. 8, when the algorithm was changing, it was 4.

By Feb. 10, it was 52.

MR. CUTTS said he did not plan to write about Penney’s situation, as he did with BMW in 2006. Rarely, he explained, does he single out a company publicly, because Google’s goal is to preserve the integrity of results, not to embarrass people.

“But just because we don’t talk about it,” he said, “doesn’t mean we won’t take strong action.”
