Google Instant is a new search enhancement that shows results as users type. Google's key technical insight was that people type slowly, but read quickly, typically taking 300 milliseconds between keystrokes, but only 30 milliseconds (a tenth of the time!) to glance at another part of the page.
The most obvious change is that users should get to the right content much faster than before because they don’t have to finish typing a full search term, or even press “search.” Another shift is that seeing results as one types helps people formulate a better search term by providing instant feedback. Users can adapt their searches on the fly until the results match exactly what they want.
Google Instant can save 2 seconds to 5 seconds per search, Google estimates. The new algorithms also will make smarter predications about what any user might be looking for.
