Google Instant is an enhancement to the Google Search that shows results as you type. With Google Instant users will be getting instant & faster search results. The thinking behind Google Instant is that the research shows that people type slowly and scan fast, so while the users are typing they can scan the results shown and choose the most appropriate out of that.

google_instant

The most obvious change is that users get to the right content much faster than before because one don’t have to finish typing your full search term, or even press “search.” This has been there in various search engines and many others are using this from a long time.

The benefits to this is that the users get instant, faster and more accurate search results. This will certainly help users in searching and most of all choosing the right keyword to get appropriate results.

Rajesh Jain is known as the man who almost single handedly brought on the dotcom boom to India after selling off his Internet venture, IndiaWorld.com, to Satyam for Rs 499 crore in 1999. He is, in effect, the first dotcom multi-millionaire that India produced.

Here is the full interview…
