How Google Instant Changes the SEO Landscape

Google Instant launched. It is a new always-on search experience where Google tries to complete your keyword search by predicting what keyword you are searching for. As you type more letters the search results change.
Not seeing it yet? You can probably turn it on here (though in some countries you may also need to be logged into a Google account). In time Google intends to make the is a default feature turned on for almost everyone (other than those with slow ISPs and older web browsers). And if you don’t like it, the feature is easy to turn off at the right of the search box, but to turn it off it uses a cookie. If you clear cookies the feature turns right back on.

Here is an image using Google’s browser size tool, showing that when Google includes 4 AdWords ads only 50% of web browsers get to see the full 2nd organic listing, while only 20% get to see the full 4th organic listing.
