The company has contacted a number of agencies about a brief to handle online communications to candidates and potential advertisers. A tender has been issued asking agencies how they would run the business from London.
The company is thought to be drawing up a longlist of around eight agencies.
The brief is separate from the business won by Arc Integrated in November for Monster's online advertising and e-mail newsletter. Arc pitched with its sister agency Leo Burnett, which won the advertising account.
Monster is also reviewing its media planning and buying business, currently handled by ZenithOptimedia.
Monster spent £2 million on ads last year, according to Nielsen Media Research, but is planning a heavyweight campaign for later this year.
Online recruitment has grown tenfold since 1999 and is now worth almost £100 million, according to the World Advertising Council. Research from the Internet Advertising Bureau last month revealed that online recruitment, along with automotive advertising, contributed to a 62.4 per cent rise in online classified advertising in 2005, to £262.2 million.
