Advertisers who have already signed up include Vodafone, gaming publisher Electronic Arts, Rank Xerox and the Greek Ministry of Culture.
Justin Farnan, sales director of Metro UK, said: "This is a commonsense agreement providing a great opportunity for clients to tap into a hard-to-reach and highly valuable audience across Europe."
Metro says that it gives advertisers the chance to reach a combined daily audience of 10.4m "urbanites" aged between 16 and 44. Metro International has newspapers in France, Spain, Italy, Sweden, the Netherlands, Hungary, the Czech Republic, Poland, Finland, Denmark and Greece, while Metro UK publishes six editions including London, Manchester and Newcastle.
Lawson Muncaster, vice-president of global ad sales at Metro International, said: "We have been successful in attracting prominent European advertisers because we deliver a highly desirable, young 'urbanite' audience across Europe every day and because, like Metro UK, we are committed to constructing advertising solutions that go beyond traditional newspaper print options."
