Acknowledgments in google scholar citations Is it acceptable to add articles under my profile in "google scholar citation" in which i was acknowledged for my real contribution rather than being a co-author?
Acceptable I'm not sure, but it really doesn't sound like a good idea.

The point of Google Scholar is to collect in one place the information on papers in which you are an author. If the paper in question was prominent enough in your profile to attract my attention, I would assume that something suspicious is going on, and there is no way for me to tell whose fault it is. Overall, it doesn't send the kind of signal you would probably want to send.
