Google Instant Previews allows you to see what’s on a website right from a Google Search results page. All you have to do is simply click the little magnifying glass icon next to a result and an overlay will appear to the right of the link, showing you what’s on the page.
Information from Google
With Google Instant you get results as fast as you type, but your search doesn’t stop there. Once you get results back, you choose a site to visit based on the information in each result—like the title, a snippet of text and the URL. Over time we’ve made steady improvements toour search results and snippets to help you pick a great page. Now we’re making a leap to image-based snapshots—a new kind of visual search result we call “Instant Previews” which makes it even faster to choose the right result.
Instant Previews provides a graphic overview of a search result and highlights the most relevant sections, making finding the right page as quick and easy as flipping through a magazine. To use it, click once on the magnifying glass next to the title of any search result and a visual overview of the page will appear on the right. From there, hover your cursor over any other result to see a preview. For those of you who’ve recently stopped using your mouse to search, now you can navigate to a result, hit the right arrow key to see the preview, and hit the down arrow key to keep browsing.
Happy Googling, Happy Previewing
