Over the weekend Rob Ousbey noticed that Google was testing updating the results shown while you are typing.
So as you type your search query into Google and the auto suggest fills out suggested search phrases so Google actually changes live the results shown. Pretty cool. But also pretty distracting.
There is a suggestion that this could be heavy on bandwidth but I think more of an issue would be over how quickly the results change depending on how quickly you type. Would they be able to keep up or would your typing, auto suggest and live changing results (and sponsored results) all lead to a somewhat confused set of results?
Also, do we need to now optimise for multiple variations of word as they are constructed? So for cheap flights think about the following options: c ch che chea cheap cheap f cheap fl cheap fli cheap flig cheap fligh cheap flight cheap flights?
Whether this is rolled out as a permanent option even for power searchers remains to be seen but an interesting development for Google and one we will be watching.
