On the planning tab above I keep an active list of great resources for anyone that needs to additional information to justify a new marketing or social media program or for general research purposes. I have made some new updates to the list that I think are pretty interesting:

SOCIAL MEDIA ROI RESOURCES

• Dell’s $3million on Twitter and other Twitter ROI Examples: Great specific examples on Twitter ROI from Dell, Cisco, Pandora – focus on sales and customer support (Read Write Web June 2009)
• Using Cost Per Click For Social Media ROI: Interesting model to calculate some hard numbers for your project – take a hard look at this one! (The Page Wonders, June 2009)

GENERAL SOCIAL MEDIA STATS

• Twitter Just a Blip So Far: Great data from Harris Interactive on Twitter adoption and usage by gender and age (5/2009)
• Women and Social Media Study: Incredibly detailed study on all social media activity of women across all ages – great data on attitudes and motivations.  (BlogHer / Compass April 2009)
• Pew Internet Project Data Memo: Great data on social networking usage by age category (1/2009)
• General Social Media Stats: Nice, clear compilation of stats across blogosphere, Twitter, google and more (Adam Singer, 1/2009)

Again, these are just the recent updates – for the whole list please go to the Planning tab.
