Google Search
Google Instant, an enhancement that displays suggested results while the user types, was introduced in the United States starting on September 8, 2010. One concern is that people might select one of the suggested results instead of finishing their request, and that such a practice could cause bias toward familiar businesses or other search terms. Pornographic or otherwise offensive search terms are excluded from the suggested results. The instant feature appears only on the basic Google site and not specialized iGoogle pages. Google expects Google Instant to save users 2 to 5 seconds in every search, which they say will be collectively 11 million seconds per hour. Search engine marketing pundits speculated that Google Instant would have a great impact on local and paid search.
