Google Instant - impact of Search Engine Optimization(SEO), Web Rankings and Website Designs

Google announces Google Instant search, available now for desktop, mobile

The Google Instant service has been activated, Google no longer waits for you to hit Enter while searching and starts updating its results page Instantly as you type. Google describes it as a fundamental shift in search.

What does this mean? Google now controls the popularity of keywords words more, people will stop typing their own keywords so websites that are not being judicial on their titles, meta tags etc might loose traffic. It also means that keywords and titles accross sites are going to be very similar as most will now 'copy-paste' what google auto suggests.
