Clickstream data is not widely known about. In short it’s the analysis of users clicking on websites. We’ve started exploring this and the clickstream we’re using is based on users clicking on particular search results. In short, if you do a search on Trip and click on documents number 2, 4 and 9 you’re effectively telling us that, for your intention, they’re connected. In isolation it’s arguably meaningless, but over thousands of searches you start to see structure. I’ve blogged about this previously (here, here and here) but now we’ve got more results.
Below is the largest continuous graph/map of connected documents – over 10,000 long (click on image to expand).
