Applying success events in search engine report
When looking at the search engine reports for organic and paid traffic, if I apply a success event metric, e.g. registrations, what exactly does this figure tell me?
How is it calculated? And what do the "Unspecified" line mean in this reports? As I understood it, it is similar to the "Nones" in other reports, which means that I should neglect it. But I did a test registration and I believe that it subsumed my registration under "unspecified" instead of the respective search engine. How's that possible?
The thing is that in the search engine reports if I sum the figures for the natural search engninges and those of the paid search engines, these added totals are not the same as the totals below the line in each report.
