Interviewing a purveyor of black-hat services face-to-face was a considerable undertaking. They are a low-profile bunch. But a link-selling specialist named Mark Stevens — who says he had nothing to do with the Penney link effort — agreed to chat. He did so on the condition that his company not be named, a precaution he justified by recounting what happened when the company apparently angered Google a few months ago.
“It was my fault,” Mr. Stevens said. “I posted a job opening on a Stanford Engineering alumni mailing list, and mentioned the name of our company and a brief description of what we do. I think some Google employees saw it.”
In a matter of days, the company could not be found in a Google search.
“Literally, you typed the name of the company into the search box and we did not turn up. Anywhere. You’d find us if you knew our Web address. But in terms of search, we just disappeared.”
The company now operates under a new name and with a profile that is low even in the building where it claims to have an office. The landlord at the building, a gleaming, glassy midrise next to Route 101 in Redwood City, Calif., said she had never heard of the company.
