In November 2010, Google launched instant previews for the search results. The concept behind this feature was not new and many called Google a copycat for launching the feature.

Either way, the feature has stuck, and it still works in the search results.

Google has recently been testing these instant previews in the AdWords ads. Matt McGee reported at Search Engine Land that these instant previews give searchers a chance to view the ad’s landing page prior to clicking on the ad.

It is unclear if and when Google will launch it.

I have to assume that clicking on the preview feature does not cost the advertiser any money.

Personally, I’d like to see this feature added to the ads.
