Robin Good: Thanks to Jason Keath and Caleb Gray who have put together this excellent collection of over 100 Facebook advertising case studies and to their specific documentation.
For each one you can find a short, one paragraph description of the campaign, an outline of the results obtained and a direct link to the official case study.
Very useful. 8/10.
