Depending on how your bookmarks are shown, the actual search results may not even make it into the first left third of the page - a setup that is guaranteed to have lower CTR by design.
This is such an important observation, and goes directly to one of the earlier posts by Tedster in this whole discussion, when he referenced these screenshots [siliconangle.com]. I just don't think we can overestimate the damage this new layout is doing to our traffic. Yes, there are also of course significant changes in the SERPs, but when you are pushed down on a page because so much other stuff is now inserted at the top, that in-and-of-itself goes a LONG way in explaining why visitor numbers have fallen off a cliff -- and the other things going on (as discussed here) make it even worse.
