Google is testing a new feature that marries its Instant Previews with AdWords. The test gives searchers a chance to see the ad’s landing page without clicking on the ad.

When Instant Previews launched in November, Danny Sullivan reported that Google was planning this:
Ads, by the way, will also get an Instant Preview feature in the future, Google told me. There’s no set timeline for this, however.
