Santa Monica-based Demand Media, the online publishing business run by Richard Rosenblatt, announced its first quarter 2012 results yesterday, and also raised its fiscal 2012 financial guidance. The firm said it had total revenues of $86.2M, an increase of 8 percent from the similar quarter last year. The firm was helped significantly in the quarter by growth in the firm's registrar business, which grew 17 percent year to year. Demand Media said it now expects full year 2012 revenues to be between $361.0M to $367.0M. Demand Media also acknowledged that changes to the search engine algorithms at Google have significantly impacted its content business, particularly at its eHow property: Demand said its RPM for its owned and operated content sites dropped by 20 percent from year to year, due to those search engine changes. The company did not address the rumors that it had recently turned down an offer to go private.
