The US Justice Department is preparing to sue Google as soon as next month, according to people familiar with the matter, capping years of work to build a case that the Alphabet Inc. unit illegally dominates the digital advertising market.

Lawyers with the DOJ’s antitrust division are questioning publishers in another round of interviews to refresh facts and glean additional details for the complaint, said three people familiar with the conversations who asked not to be named discussing an ongoing investigation.
