The IMEC Lab (Internet Marketing Experimental Cooperative) is a group of web marketers dedicated to uncovering knowledge about how search & social platforms like Google, Facebook, Twitter operate. We pursue confirmation of hypotheses by quitely performing live tests on the web, and sharing the results publicly once experiments have ended.
IMEC Lab is run by Rand Fishkin of Moz. For details, visit the blog post: http://moz.com/rand/imec-lab/
