Google has introduced Instant Previews, a new search feature that displays a preview of each search result.
Typically, the title, URL and the text description in each search result help users determine which results are best for them. With Instant Previews, the same goal with a visual representation of each page will help users even more to determine which results are best for them.
With Instant Previews, if you click on the magnifying glass on any result, a zoomed-out snapshot of the page appears to the right of the result. Orange highlights indicate where the relevant content on this page is, and text call outs show search terms in context.
Instant Previews allow users to know what to expect when they click on that result.
