Hi Tracey, In my dissertation I have developed a number of approaches to map data flows between social media platforms and other platforms and websites, see: Helmond, Anne. “The Web as Platform: Data Flows in Social Media.” Ph.D. University of Amsterdam, 2015. http://dare.uva.nl/record/1/485895 In developing methods these for mapping data flows I have been greatly indebted to the work of Greg Elmer and Ganaele Langlois (and Fenwick McKelvey) whose two articles on this topic I can highly recommend: Langlois G, McKelvey F, Elmer G, et al. (2009) Mapping Commercial Web 2.0 Worlds: Towards a New Critical Ontogenesis. *Fibreculture* (14). Available from: http://fourteen.fibreculturejournal.org/fcj-095-mapping-commercial-web-2-0-w... Elmer G and Langlois G (2013) Networked campaigns: Traffic tags and cross platform analysis on the web. *Information Polity* 18(1): 43–56.
