Hi Charlie,
Thanks for writing in and sorry that some of your campaign data is looking off.
We aren't having any general issues with traffic data at this time, so I am going to give you a run down of how to double-check your organic traffic in Google Analytics so you can see exactly the data we pull from the Analytics profile.
Log in to GA and select the profile that the campaign is connected to
Click 'Traffic Sources' in the left navigation
Click 'Sources' in that sub-menu
Click 'Search' in that sub-menu
Click 'Organic' in that sub-menu (after clicking organic the graph & data refreshes)
Click the down arrow next to the date range in the top right corner (expands a date picker)
From the Date Range dropdown select '1/21' to '1/27' (for example) and click 'Apply' (graph & data refreshes)
If you are seeing traffic in that data once you follow the list above, please send us a screenshot so we can look into why we aren't pulling the data in on your account.
As for the duplicate content, our engineers recently made an update to the crawler that made the check for duplicate content more accurate and it seems that your campaign has been affected by this change. I checked a number of the pages that we are listing through the similar page checker here: http://www.webconfs.com/similar-page-checker.php and all of the pages that I checked that our crawler is reporting as duplicates and it looks like all of those pages are showing as 100% similar in that tools, so it does seem we are accurately reporting your duplicate content pages.
I hope this helps. Please let me know if you have any other questions.
