Google's plans are to monitor the movements of the cursor, such as when a user hovers over a certain ad or link to read a tooltip, and then provide relevant search results, and ads, based on that behaviour (sic). It means that it does not require users to actually click a link to know that they were interested in it
Very interesting idea. A lot can be learned by monitoring this behavior including stats like
"Hovered and passed" "Hovered and clicked" "Clicked with no hover"
Hope they share, it would help developing ad, title and blurb copy.
The patent also notes that hovering over a OneBox result might be a signal to Google that there's value in presenting that particular OneBox within the results.
The patent was filed a couple of years before Google implemented Universal Search, but if they were to use this kind of mouse pointer tracking, it's possible that it could be used for all kinds of vertical results interleavened within web results as well.
I guess it is a little spooky, but not really. I know in other areas Google has done some pretty spooky and outright stupid stuff.
One thing I have always loved about them and continue to praise them for is their search results. More specifically the relevance of their results to me.
Most tricks they employ to make results more relevant I am for as long as it isn't recording things I have an expectation of privacy on. I don't think of my mouse over and mouse placement as something I would expect to be private.
