Google has apparently begun testing full page previews in its search results.

Both Blogstorm and TheNextWeb have captured screenshots of the new feature, which allows you to view a miniature version of a page before you click on it. If you have the preview tool enabled, simply hold your mouse over a link to see it in action. Google even highlights sections of the page where the text you've searched for is mentioned.

The company has displayed a renewed interest in improving its core search product lately, having rolled out Google Instant, a feature that pulls up search results as you type, just last month. Google has released further improvements to the product since then, including keyboard navigation.

We're not yet sure whether Google is merely testing full page previews or rolling it out to all users. We've reached out to the company for further information and will update this post when we have it.

Update (2:53 p.m. ET): "At any given time we are running between 50-200 search experiments," a Google spokesperson said in an e-mail to Mashable.
