Facebook Adds "Social Context" Metric For Advertisers

Yesterday, Facebook began displaying a new metric for advertisers called “Social Context”, which “tells you the percentage of your ad’s impressions where the viewer saw at least one friend who liked your Page, event, application, or ad.” It’s a valuable metric, however based on our tests, the correlation between a high “social context” and high click through rates are strong, yet not perfect. For example, we were able to find ad campaigns which had very low social context, but extremely high click through rates due to effective targeting.
