The
activity percentages are more meaningful and accurate than the traffic. Actions on NamePros are essentially all performed by real people (99.99%?) thanks to years of tech development, whereas visits include
all sorts of robots (e.g., crawlers). As
we mentioned, moderators don't have access to Google Analytics, but the data is
not comparable in the way you want, anyway.
Here's a simplified way to think about it: do you want the domain name with 1000 visits and 0 clicks, or the domain with 10 visits and 5 clicks, if you're purely interested in domain monetization? The latter.
Alexa.com is not necessarily less accurate either, for
the reasons we mentioned and because Alexa tries to approximate the
true value, whereas Google Analytics only reports what it sees and does not try to account for the significant amount of traffic that it doesn't see (e.g., due to being blocked by a browser/extension, which again, is not consistent over time and therefore cannot simply be ignored or factored out of the equation).
We hope that helps.
