Social Network Advertising on the Up-and-Up

Great news today coming out of eMarketer regarding SNS (Social Networking Services) and ad spend. According to the report, Social Network Marketing: Ad Spending and Usage, “social network ad spending is expected to grow by 81%, to $2.2 billion in 2008 from $1.2 billion this year” and “spending [in the US] is projected to rise to $1.6 million in 2008, from $920 million in 2007.”

A large portion of the spend is coming from deals between the two largest SNS properties: Microsoft/Facebook and Google/MySpace.

I’d be interested to see what details and best practices are mentioned for targeted ad spend on SNS within the report. Neither I or famed SNS researcher, danah boyd, have seen relevant evidence to track eyeballs into actions.
