Measures of (Social-Media) Success

A modest tracking dashboard

PostRank provides detailed information on tweets, stumbles, Diggs and FriendFeed all in one place. It's suited to blogs and websites with a lot of content. Under its free plan, you can track and compare your sites and your competition — up to five sites in all — to get the full picture of your social engagement. You can also track your static and offsite content (PDFs, YouTube videos, SlideShare content) for up to 10 sites.
