We're running a Facebook news feed ad that is pointing at our homepage. Facebook says that for yesterday there were 47 website clicks. Google analytics shows 15 total visitors from facebook with 3 of them landing on the homepage. I understand that there is likely going to be some discrepancy with users accidentally clicking and clicking back before the page loads, but this seems a little insane. I tested the ad using a page that pulls the Analytics cookie data using php and it is working properly so I don't understand what's happening. The url isn't tagged with utm parameters, which is going to be fixed.  Anyone experience this or have any insight as to what could be this issue? Is this click fraud? Edit: For more clarification I was checking on my completely unfiltered google analytics profile/view.
