Google’s been speeding things up lately, as you’ll know if you’ve turned on Google Instant for your searches. (See Google’s Instant Search: An Alphabet Book.)
Now Google’s rolling out Instant Preview, which, as the name suggests, lets you get a preview of the site itself. I’m not one of the lucky rolloutees yet, but Google, ever solicitous, has a Google Labs site that will let you play with the new feature. You’ll know when it arrives in your neighbourhood, because a small magnifying glass icon will a appear beside each of your results.
A click on it brings up a small popup window containing the relevant site. Once you’ve called up any preview, you can simply put your cursor on any of the other search results to cause its preview to appear. Neat.
You can read more about it on the Google Official Blog.
