Today, we announced the launch of Google Instant, an innovative new Google.com interface that creates an interactive search experience for users by predicting their query as they type and instantly showing updated results.
This new interface applies to both search results and related ads. Therefore, we expect increased user engagement with our search services, including ads.
For a complete update on changes to the users' search experience, please visit the Official Google Blog. For details on how this may affect advertisers, visit the Inside AdWords Blog.
