Google experiments with a new feature that previews full-page search results when you mouse over them. “I started to get a highlighted-box mouse-over effect along with that magnifying glass icon on most of my search result entries. Clicking on it toggles a preview image with some text highlighted as well. The image preview differs slightly depending on where the aforementioned text appears on the page.”
According to Altoft, Google highlights certain sections of the page preview in orange and expands the text to provide a snippet of information. These highlighted snippets aren’t always the same as the snippet in the search results, he adds.
Surprisingly, Google also started showing multiple results from the same site without indenting the results.
The feature seems to be inspired by Ask.com’s Binoculars, but it’s a little more clever because it highlights relevant snippets, so you can quickly find them when you visit the page.
