Mother pitched against VCCP, Bartle Bogle Hegarty, DDB, Adam & Eve and Fallon. The review was overseen by Match.com's marketing director, Karl Gregory.
The online dating site's ad account had previously been held by Hanft Raboy and Partners.
Gregory joined the company in February and is aiming for the brand to move toward a 'mature' positioning in 2010.
The dating company initially began speaking with agencies about the advertising account in July, although the company at the time said no agencies had been formally invited to pitch.
Last month, Jason Stockwood, who had been managing director of Match.com left the business after three years at the helm.
Match.com spent about £6m on advertising in the UK across TV, outdoor and radio last year, according to Nielsen.
Gregory said:‘The new campaign will work hard to engage people with the category on an emotional level. Love is, after all, the essence of our brand.'
