Realtor.com operator Move Inc. reported first quarter revenue was up 14 percent from a year ago to $54.2 million — the biggest quarterly year-over-year growth in more than six years today. Average monthly unique users grew 10 percent, to more than 28 million, and mobile app users grew by more than 60 percent, accounting for nearly half of all listing detail pages viewed in the quarter. While consumer advertising revenue was up 7 percent, to $42.1 million, revenue from software and services jumped 46 percent, to $12.1 million. Last October, Move acquired lead-generation company Relocation.com for $11.5 million, a move that followed on the heels of the acquisition of lead-generation and management firm TigerLead Solutions LLC for $22 million. Move said today that during the first quarter, TigerLead “outperformed expectations by adding more new customers than in any prior quarter and achieved higher growth rates than planned.” Earlier today, Move disclosed that it had acquired Doorsteps operator ABC Holdings LLC. Move started off the year by purchasing a housing-trends newsletter produced by eFrogPond Inc. Source: Move Inc.
