"Drs. Daniel Pauly, director of the Fisheries Centre at UBC and Stergiou (of Aristotle University in Greece), compared WoS and Google Scholar using 114 papers from 11 disciplines from 1925 to 2004. With papers published pre-1990, they found that citation counts were more or less proportional. When Thomson ISI revealed that a paper was cited 10 times as often as another in the same field, Google Scholar usually found the same 10-1 ratio. Surprisingly, for post-1990 papers, the actual number of citations was almost the same."

Another study that reaches some of the same conclusions: http://arxiv.org/abs/cs.IR/0504036

They seem to be popping up like dandelions in the fields ;-) (Please read my post on ALL possible options to get to a PDF: http://digicmb.blogspot.nl/2017/03/how-to-get-pdf-infographic.html ) Here is a first glance of what they do. For testing i used this article: http://dx.doi.org/10.1016/j.cub.2016.10.008 (not free or open access) Kopernio (previously Canary Haz ( http://kopernio.com) Note this is a .com extension. This new company has been founded just 8 months ago. The Kopernio extension was released just in March 2017. Currently the Kopernio button is in alpha-testing and so far it seems free. The previous name appeared to be a tribute to the #ICANHAZPDF movement (requesting pdf's via Twitter with this hashtag). ...
