For the last days i'm seeing the same thing. I see a 300% increase in impressions, but no significant increase or decrease in clicks ...so traffic remains the same.

Deeper inspection shows that the site (which I believe was hit by both Panda & Penguin), is now ranking at the bottom of page 1 and on Page 2 for some low-volume keywords. That explains the increase of impressions while traffic remains about the same... at least for me.
