Instant results instantly
“Google Instant went live for the USA and a number of other countries last week to an energetic response from the SEO and tech blogosphere. How impressions reported in Google Webmaster tools and Adwords, and the death of the long tail query was discussed at lenght. Briefly, Google Instant shows the user the results of the search Google thinks they are doing based on what they type as they type it. Google Instant is not available for Australian users yet, but can be tested here: http://www.google.com/webhp?sclient=psy.”
