Were my visits down? Were they up? Do I see duplicate transaction records? Do the dollar amounts I see match complementary records from finance?<BR/><BR/>The reason to ask these questions isn't that the analyst is an idiot. It's that online measurements systems generate data a lot of data on visitors, and there are so many ways for that data to be wrong...and so few indicators that data is wrong OTHER than abnormal volumes or conversion rates, or customer pathing.<BR/><BR/>Also, there may be some obvious reason why my site conversion rate would spike - from statistical noise to external factors..arrival of that "economic boost" check...some free press...or maybe that free trial offer on the homepage. Most of these factors can be accounted for...but they should be considered when reviewing the way.<BR/><BR/>And I'd make sure I understood the why - or had a plausible explanation for it - before I ran to the VPs with it.Unknownhttps://www.blogger.com/profile/08659348302720417457noreply@blogger.com
