The new campaign will drive traffic to the website, where a promotion gives anyone requesting an online quote the chance to win one of two MG cars.
Customers who use the site to buy insurance will also get a 5% discount.
Liz Penighetti, senior marketing executive at Churchill Insurance, said: "We have set ourselves ambitionous growth targets for digital media, but with our innovative service and the direct marketing experience of AWA3D we are convinced we can achieve our goals."
Churchill Insurance is famous for its "give a dog a phone" advertising campaign, featuring the voices of Vic Reeves and Bob Mortimer. Last week, it was bought by the Royal Bank of Scotland in a 拢1.1bn cash deal.
AWA3D was launched by media agency Anderson Weinrib & Associates earlier this year.
