Its certainly a big change, and there are a number of fundamental changes.
- Results change as you type. This isn’t necessarily on each word, but certainly as each default suggest change happens
- I understand impressions will only be triggered once users have settled on a result for a particular period of time. This is TBC (as written before launch)
- This is not available on mobile – however there are plans to release soon
- This is rolling out to users on US, UK, France, Germany, Italy, Spain and Russia who are browsing on Chrome v5/6, Firefox v3, Safari v5 for Mac and Internet Explorer v8
- 15 new technologies contribute to Google Instant functionality. One of these would be the Ajax result functionality
- Google reckon this could save between 2 and 5 seconds per search
According to Google
Google Instant is a new search enhancement that shows results as you type. We are pushing the limits of our technology and infrastructure to help you get better search results, faster. Our 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. This means that you can scan a results page while you type.
I’ll be honest I didn’t realise this was as bigger problem as it now appears, and from a personal perspective, we will see whether this stays activated or turned off as with many other Google features….
