Sharp drop off in conversion rate in Google Analytics
I am seeing sharp drop offs (.99% in May vs. .10% in June) in Google Analytics conversion rate for three of my client's goals, and all three drop offs happen on the same day, that day being May 26th. The goals are all destination goals, all of them are set up as funnels, and required is checked no on all three as well.
I am trying to understand what would cause something like this as major changes to the design of the pages did not occur as far as I am aware. We had recommended that the client 301 all of their non-secure pages to the corresponding secure versions around that time. Would 301 redirects of that sort have anything to do with it?
