Reading my twitter feed this morning I found this little gem posted by @MichaelHalbrook, a consultant at Adobe, back in July on the Adobe Omniture Blog. It is a very nice overview of one of the most asked questions any one that supports Adobe Omniture Insight gets, what is “Small Elements”. It is a very good read with a lot of good information.

Unfortunately a denormal dimension isn’t “always capable of showing you the real top elements”. When you have well over 5 million unique items and thousands added daily there isn’t enough ways to filter things down to just 1024 items, but fortunately we have Segment Exports or even a full Visual Transform to pull out all the uniqueness. That data could then be stored in a warehouse so that you can get at the “Long Tail”.
