Web Analytics - some interesting observations

I just downloaded a pdf entitled: 25 Real Stories of Better Results through Web Analytics, from the NetIQ site. Though it is obviously trying to promote Web Trends and its new WebTrends 7 product, it does have some interesting insights into how web analytics can help flagging websites. Though some of the functionality can be found from current statistics packages, other advanced features would have to be acquired through purchasing this product, entry level prices start at $495.

Here's one such story:

"We used to send a hint of the Tip Of The Week to our partners on Fridays, with a click-through rate of 23%. The landing page contains a full text of the Tip and a mini-survey checking how valuable, innovative and applicable the Tip is to the reader, providing us with useful input. Last September, after viewing our reports, we found that Mondays have more intense traffic than Fridays. We started sending the Tips on Mondays and almost doubled the click-through rate to 44%!"
