According to the Wall Street Journal’s CIO Journal blog, Facebook’s head of analytics believes there is value in knowing where users’ cursors go and in which parts of the screen they hover at any given moment.
Facebook wants to know things, like “did your cursor hover over that ad… and was the newsfeed in a viewable area,” explains Mr. Analytics, who used to work at Zynga, the company responsible for many of those obnoxious game requests you ignore.
The website is currently testing this cursor tracking, not to see if it’s possible, but to see if it yields any useful data.
“We probably will know in a couple of months,” says Analyticus Prime, admitting that there is such a thing useless information. “Instead of a warehouse of data, you can end up with a junkyard of data.”
