It has seen revenue increase by 20% to £47.0m and its interim dividend increased by 40% to 7.0p per ordinary share.
Ed Williams, managing director of Rightmove, says its iPhone, iPad and mobile applications have proved a success.
He says: “People are now home hunting wherever they are, not just at home or work. People thinking of selling their home know it remains a challenging housing market, so they increasingly expect their estate agent to make sure that their property is advertised as prominently on Rightmove as possible.
“Continuing to grow revenue and profits in the current housing market is the result of the importance of Rightmove to home hunters and property advertisers alike and a tribute to all the efforts of our people.”
