Wulff has denied that she has ever worked as a prostitute.
However, Google said that the auto-generated text reflects what others are already searching for online, the BBC reports.
Wulff has spent over two years fighting allegations she was once employed as an escort, a German newspaper noted.
“Her lawyers have already issued 34 successful cease-and-desist orders, including one against a prominent German television personality this weekend,” the paper said.
The same paper said a defamation suit was launched against Google last week.
Head of PR for Google Germany, Kay Oberbeck, said the site''s search terms were "algorithmically generated" and "include the popularity of the entered search terms".
"All terms that appear have been previously entered by Google users," he added in a statement.
