Hello,
We are trying to calculate the click-through rate of some page Modules. So, the CTR should be = # Module Clicks / # Module impressions.
To capture the Module impressions, we pass the list of page Modules into s.list and fire the Module impression event (event39):
s.events="event39"
s.list3="Mod1,Mod2,Mod3" - the list of Module IDs of all Modules displayed on a particular page
Then, when a user clicks on any particular Module, we pass the Module's name and Module click event (event24):
s.events="event24"
s.list3="Mod2"
Unfortunately, the Module Clicks captured by event24 are getting allocated to every list value fired on the first call - "Mod1,Mod2,Mod3" rather than to a single value fired in the second call - s.list3="Mod2". As a result, the # of clicks per each module is getting substantially inflated.
We tried to change the expiration term of the list variable, but it didn't make sense:
- If we expire s.list3 on event39 (Module Impression event), none of subsequent Module click events (event24) would be allocated to the proper Module names
- If we expire s.list3 on event24 (Module Click event), the number of Module impression will be inflated in case nobody clicked on the Module and the user proceeded to another page with a new set of s.list values
- IF we expire s.list3 on the Page View, it wouldn’t help either since if would allocate the clicks events to all impression-based s.list values
I would greatly appreciate if anyone could point the flaws of our implementation.
PS. - this approach was described by Adam Greco in his “The Adobe SiteCatalyst Handbook. An Insider’s Guide’ , pages 283-285.
Thanks!!!!!
