When your Openr link is clicked (in social, or email for example) the content you shared will load along with your Openr - that’s called a viewer, and the person who clicked is the viewer. At this point, the content that you shared (the Content URL) loads within the viewer’s actual browser which means it will show up in the analytics of the content owner and they will be able to see the viewer details like normal - including their IP address and other attributed information (like the browser used). So if it’s your content you’ll see all that info, or if you’ve shared third party content they will be able to see the traffic as normal.
In terms of referral data, since Openr triggers the load of the content (Content URL) the referral will be recorded as an Openr link (http://openr.co/AABBCC) in the analytics system of that content - irrelevant of where the link was shared and clicked on. i.e. if you’ve shared the link in Twitter the analytics will not know the visitor (viewer) came from Twitter, it will be recorded as Openr. But don’t forget, if you’re sharing your own content as the Content URL, you’ll have all the tracking in Openr Analytics telling you where the views and clicks came from under Referrals and Regional stats..
From an SEO perspective, the weight of the link shared is split between Openr and the Content URL (since it is included into Openr link) and of course, no one (except Google) knows how this weight is shared. There is a lot written about the impact of URL shorteners (like bitly etc) on SEO weighting, and it seems the general view is it has little or no impact hence we believe that there is no difference to the Content URL website if it is linked directly or through Openr system.
