Google is moving away from the traditional HTML based results to a more robust AJAX based application for delivering ‘real’ time search results. Marissa Mayer noted that Google has already made approximately 500 changes to search ranking and user interface (UI) in 2010.
It takes a user on average 9 seconds to enter a search query followed by a few hundred milliseconds on Google’s Servers to render a search result. The user then averages about 15 seconds looking at the results. Google Instant claims to save user 2-5 seconds per query, which in turn will save 11 aggregate hours per second.
Google will display characters in black that they have typed followed by shifting grey predicted characters as the user continues to type. Why even keep the search button at this point? Well it forces Google to search for exactly what you’ve typed, without predicting how you’ll finish that search.
Instant will begin rolling out to Google domains in the US, UK, France, Germany, Italy, Spain and Russia who use the following browsers: Chrome v5/6, Firefox v3, Safari v5 for Mac and Internet Explorer v8.
