Don’t be surprised if you go to your Google Analytics and try to quickly check in on your search traffic and possibly start freaking out that Google dropped the feature.
They didn’t drop the organic search results or remove it, they just restructured it.
Google said on Google+ that they’ve “restructured” it to make it “easier” for users to use. They even placed this warning at the top of the acquisition reports to warn users (which doesn’t seem to be doing the job).
Google wrote on Google+ why they made the change:
It shouldn’t take you too long to pick up on the changes and get where you need to get to today.
